    Customization Guidelines

    This section contains general guidelines on how the functionality of EAGO can be extended for specific use cases. Many functions in EAGO are extensible, so examples are not provided for every possible case, but some important functions are covered. If there is a use case you do not see provided here, but would like to see, please contact Robert Gottlieb.

    1) Creating an Extension

    Extensibility in EAGO is based on the ExtensionType. To create customized functions, the recommended method is to create a new structure, as follows:

    using EAGO
+
+struct MyNewStruct <: EAGO.ExtensionType end

    To let EAGO know that you would like to use this extension (and any functions you overload), when you create the JuMP model, declare your new type in the subsolver_block field of the Optimizer as follows:

    using JuMP
+
+factory = () -> EAGO.Optimizer(SubSolvers(; t = MyNewStruct() ))
+model = Model(factory)

    The key point to note here is that the new structure is set to SubSolvers.t, which is the field that holds any user-defined extension type. Now, when EAGO calls any of its functions, it will check to see if a custom function for this new extension has been created. If so, it will use the new one; if not, it will use the default version of that function.

    2) Preprocessing

    In EAGO's branch-and-bound routine, preprocessing is performed prior to solving the lower and upper problems. By default, linear and quadratic contractor methods are performed, followed by interval constraint propagation, then optimization-based bounds tightening. An important outcome of EAGO's default preprocessing is that the _preprocess_feasibility field of the GlobalOptimizer is set to true, unless the subproblem at the current node has been proven infeasible. Therefore, to bypass preprocessing for your own problem, you must, at a minimum, set this field to true. For example:

    import EAGO: preprocess!
+function EAGO.preprocess!(t::MyNewStruct, x::EAGO.GlobalOptimizer)
+    x._preprocess_feasibility = true
+end

    The user-defined preprocessing step can be as simple or complex as desired, but if _preprocess_feasibility is not set to true, EAGO will assume each node is infeasible.

    3) Lower Problem

    By default, EAGO applies Kelley's cutting-plane algorithm [1] to solve the lower-problem. This can be overloaded using the same syntax as for the other functions. Necessary changes to the GlobalOptimizer that occur within the lower problem are changing the _lower_objective_value and _lower_feasibility fields. If the _lower_objective_value field is not changed, branch-and-bound will not update the lower bound. If _lower_feasibility is not set to true, the node will be discarded as infeasible. A minimum functional (though not useful) lower problem extension is as follows:

    import EAGO: lower_problem!
+function EAGO.lower_problem!(t::MyNewStruct, x::EAGO.GlobalOptimizer)
+    x._lower_objective_value = -Inf
+    x._lower_feasibility = true
+end

    Any arbitrarily complex lower problem can be substituted here in place of EAGO's default method, as long as these fields are updated. Note also that, although there is a separate upper problem function, if the lower problem is being replaced by an algorithm that also calculates an upper objective value, the necessary fields to update in upper_problem! can simply be updated here, and the upper_problem! can be overloaded by a function that does nothing.

    4) Upper Problem

    By default, the upper-bounding problem is run on every node up to depth upper_bounding_depth, and is triggered with a probability of 0.5^(depth - upper_bounding_depth) afterwards for continuous problems. For integer problems, this approach is used in addition to running on every node up to depth upper_bounding_depth + cont_depth, with another trigger of probability 0.5^(depth - upper_bounding_depth - cont_depth). The upper_bounding_depth and cont_depth are fields of EAGOParameters and can be changed from their default values when the JuMP model is created, or at any time afterwards. If any of these trigger conditions are met, the default EAGO upper problem runs a local NLP solve.

    The important fields to update in the upper_problem! are the _upper_objective_value and _upper_feasibility fields. If _upper_objective_value is not updated, the upper bound in the branch-and-bound algorithm will not update and the problem will not converge. If _upper_feasibility is not set to true, then any changes made to _upper_objective_value will not be updated for each node and the problem will not converge. A minimum functional (though not useful) upper problem extension is as follows:

    import EAGO: upper_problem!
+function upper_problem!(t::MyNewStruct, x::EAGO.GlobalOptimizer)
+    x._upper_objective_value = Inf
+    x._upper_feasibility = true
+end

    This example upper problem will set the upper bound on the objective value to Inf for each node. Given that no useful information is provided here, we could also have set x_upper_feasibility to false (or equivalently, remove the line where we set it to true), and the global upper bound would never be updated.

    Note that if the _upper_objective_value is changed elsewhere, such as in the definition for the lower_problem!, the _upper_feasibility flag must be set to true. If this is not done, the change to the _upper_objective_value will be discarded.

    5) Convergence Check

    By default, EAGO checks to see if the lower and upper bounds have converged to within either the absolute or relative tolerance. This method of checking convergence may not be desired if, for example, only the absolute tolerance is relevant, and you want to ensure that the program does not end prematurely due to a relative tolerance limit being reached. The fields to check are _lower_objective_value and _upper_objective_value for the best-identified global lower and upper bounds, respectively. This function should return true if the lower and upper bounds have converged, and false otherwise. An example of how to specify that the convergence check only use the absolute tolerance is as follows:

    import EAGO: convergence_check
+function EAGO.convergence_check(t::MyNewStruct, x::EAGO.GlobalOptimizer)
+    gap = (x._upper_objective_value - x._lower_objective_value)
+    return (gap <= x._parameters.absolute_tolerance)
+end

    6) Postprocessing

    Postprocessing is the final step before a node is branched on. By default, EAGO performs duality-based bounds tightening [2] up to an iteration limit set by dbbt_depth in the EAGOParameters field. The important field to update in postprocessing is _postprocess_feasibility, which must be set to true for EAGO to branch on any given node. The minimum working postprocessing function is therefore:

    import EAGO: postprocess!
+function EAGO.postprocess!(t::MyNewStruct, x::EAGO.GlobalOptimizer)
+    x._postprocess_feasibility = true
+end

    If _postprocess_feasibility is not set to true, no nodes will be branched on.

    7) Termination Check

    This is the check that occurs on each iteration of the branch-and-bound algorithm that determines whether the algorithm continues or not. By default, several conditions are checked for such as the satisfaction of absolute or relative tolerances, solution infeasibility, or other specified limits. This function returns true if any of the stopping conditions have been met, and branch-and-bound should stop, and false otherwise. The important fields to update are _end_state, which takes values of EAGO.GlobalEndState, _termination_status_code, which takes values of MOI.TerminationStatusCode, and _result_status_code, which takes values of MOI.ResultStatusCode. Combined, these fields provide information about the branch-and-bound completion status and result feasibility.

    As an example, suppose we have updated the convergence_check function to only check for absolute tolerance, and based on our knowledge of the problem, this is the only condition we care about, and we know the solution will be optimal. We could then overload the termination_check function as follows:

    import EAGO: termination_check
+function EAGO.termination_check(t::MyNewStruct, x::EAGO.GlobalOptimizer)
+    flag = EAGO.convergence_check(t, x)
+    if flag
+        x._end_state = EAGO.GS_OPTIMAL
+        x._termination_status_code = MathOptInterface.OPTIMAL
+        x._result_status_code = MathOptInterface.FEASIBLE_POINT
+    end
+    return flag
+end

    EAGO.lower_problem! — Method

+)
+

    Constructs a relaxation of the MINLP on node y and solves it using the default EAGO relaxation scheme. By default, EAGO applies Kelley's algorithm (from Kelley Jr., J.E.: The cutting-plane method for solving convex programs. J. Soc. Ind. Appl. Math. 8(4), 703 to 712 (1960)) while cut_condition(m) returns true then activates the integrality constraints of the relaxed problems and solves the resulting MILP relaxation. results are stored to the _lower_solution, _lower_termination_status, _lower_primal_status, _lower_dual_status, _lower_objective_value, and _lower_feasibility. Further, lower and upper variable duals are stored _lower_lvd and _lower_uvd, respectively, for use in duality based bound tightening. If relaxation-based bounds are weaker or cutting-planes are numerically poorly ill-posed, then interval bounds are used instead. If the problem is dual feasible but the primal status is ambiguous the dual objective value is used for the lower bound to avoid numerical issues.

    source
    EAGO.optimize_hook! — Method
    optimize_hook!(t::ExtensionType, m::Optimizer)

    Provide a hook for extensions to EAGO.

    The user-defined extension of optimize_hook! is used in EAGO's overloading of MOI.optimize! (see EAGO.jl/src/eago_optimizer/optimize/optimize.jl). Without the optimize_hook! specified, EAGO will run initial_parse!, parse_classify_problem!, and then optimize! using the parsed problem type. The user-specified optimize_hook! should thus take the new extension and Optimizer as inputs and will execute when the user writes optimize!(model).

    Example

    Here, optimize_hook! is used to bypass EAGO's problem parsing and treat every problem using its branch-and-bound routine. This is done in this example by telling EAGO to treat the problem as a mixed integer nonconvex problem, which normally dispatches to branch-and-bound.

    struct MyNewExtension <: EAGO.ExtensionType end
+import EAGO: optimize_hook!
+function EAGO.optimize_hook!(t::MyNewExtension, m::Optimizer)
+    initial_parse!(m)
+    optimize!(EAGO.MINCVX(), m)
+end

    The same functionality could be accomplished by setting the EAGOParameter field force_global_solve to be true.

    • SOCP: Second-order cone program; sent to optimize_conic.jl
    • MINCVX: Mixed-integer nonconvex; sent to optimize_nonconvex.jl

    If the force_global_solve parameter is set to true, parse_classify_problem! will set the problem type to MINCVX to pass the problem to optimize_nonconvex.jl.

    Advanced-Use Example 2

    This example is also provided here as a Jupyter Notebook.

    An $\alpha$BB Example for a QCQP.

    In this example, we will demonstrate the use of a user-defined lower-bounding problem that uses $\alpha$BB convex relaxations. In this example, we wish to solve the nonconvex quadratically constrained quadratic program (QCQP):

    \[\begin{aligned} +& \min_{\mathbf x \in \mathbb{IR}^{2}} \frac{1}{2} \mathbf x^{\rm T} \mathbf Q_{f} \mathbf x + \mathbf c_{f}^{\rm T} \mathbf x \\ +{\rm s.t.} \; \; & g_{1}(\mathbf x) = \frac{1}{2} \mathbf x^{\rm T} \mathbf Q_{g_{1}}\mathbf x + \mathbf c_{g_{1}}^{\rm T} \mathbf x \leq 0 \\ +& g_{2}(\mathbf x) = \frac{1}{2} \mathbf x^{\rm T} \mathbf Q_{g_{2}} \mathbf x + \mathbf c_{g_{2}}^{\rm T} \mathbf x \leq 0 \\ +\end{aligned}\]

    with $\mathbf Q_i\in\mathbb R^{2\times 2}$ not positive semidefinite for any $i$.

    using JuMP, EAGO, Ipopt, LinearAlgebra

    Custom Function Definitions

    For convenience, we'll define the following function that returns all the problem data $\mathbf Q_i$ and $\mathbf c_i$.

    function QCQP_setup()
+
+    Qf = [3.0, 3/2; 3/2, -5.0]
+    cf = [3.0; 2.0]
+
+    Qg1 = [-2.0, 5.0; 5.0, -2.0]
+    cg1 = [1.0; 3.0]
+
+    Qg2 = [-6.0, 3.0; 3.0, 2.0]
+    cg2 = [2.0; 1.0]
+    
+    return Qf, cf, Qg1, cg1, Qg2, cg2
+end

    The next function we'll define will take as input data for a particular quadratic function and the interval bounds on the decision variables, and construct an $\alpha$BB convex relaxation of that function. Since we're solving a QCQP, we'll use the eigvals function to directly compute the eigenvalues of the input $\mathbf Q_i$ matrix.

    function αBB_relax(Q::Matrix{T}, c::Vector{T}, xL::Vector{T}, xU::Vector{T}, x::Real...) where {T<:Float64}
+    α = max(0.0, -minimum(eigvals(Q))/2)
+    y = [x[1]; x[2]]
+    cv = 1/2*y'*Q*y + c'*y + α*(xL - y)'*(xU - y)
+    return cv
+end

    Redefine the Lower-Bounding Problem

    The following code first defines our EAGO extension (custom version) struct and then it redefines the lower-bounding problem as our own version. That is, when we call this customized version of EAGO to solve the problem, it'll deploy this version of the lower-bounding problem instead of the default version. 

    import EAGO: Optimizer, GlobalOptimizer
+
+struct αBB_Convex <: EAGO.ExtensionType end
+import EAGO: lower_problem!
+function EAGO.lower_problem!(t::αBB_Convex, opt::GlobalOptimizer)

+    xL = n.lower_variable_bounds[1:2]
+    xU = n.upper_variable_bounds[1:2]
+    # Get the problem data

+    pstatus = MOI.get(mL, MOI.PrimalStatus())
+
+    solution = JuMP.value.(x)
+    # Interpret status codes for branch-and-bound
+    if EAGO.local_problem_status(tstatus, pstatus) == EAGO.LRS_FEASIBLE
+        opt._lower_objective_value = JuMP.objective_value(mL) 
+        opt._lower_solution[1:length(solution)] = solution
+        opt._lower_feasibility = true

+    else
+        opt._lower_feasibility = false
+        opt._lower_objective_value = -Inf
+        opt._cut_add_flag = false
+    end
+    return
+end
    Note

    By default, EAGO solves the epigraph reformulation of your original problem, which increases the original problem dimensionality by +1 with the introduction of an auxiliary variable. When defining custom routines (such as the lower-bounding problem here) that are intended to work nicely with default EAGO routines (such as preprocessing), the user must account for the new dimensionality of the problem. In the code above, we wish to access the information of the specific B&B node and define an optimization problem based on that information. However, in this example, the node has information for 3 variables (the original 2 plus 1 for the auxiliary variable appended to the original variable vector) as $(x_{1}, x_{2}, \eta)$. The lower-bounding problem was defined to optimize the relaxed problem with respect to the original 2 decision variables. When storing the results of this subproblem to the current B&B node, it is important to take care to store the information at the appropriate indices and not inadvertently redefine the problem dimensionality (i.e., by simply storing the optimization solution as the lower_solution of the current node). For problems that are defined to only branch on a subset of the original variables, the optimizer has a member _sol_to_branch_map that carries the mapping between the indices of the original variables to those of the variables being branched on. Visit our quasiconvex example to see how this is done.

    (Optional) Turn Off Processing Routines

    Turn off preprocessing routines if you don't want to use them as defined in EAGO. 

    import EAGO: preprocess!
+function EAGO.preprocess!(t::αBB_Convex, x::GlobalOptimizer)
+    x._preprocess_feasibility = true
+    return
+end

    Turn off postprocessing routines if you don't want to use them as defined in EAGO. 

    import EAGO: postprocess!
+function EAGO.postprocess!(t::αBB_Convex, x::GlobalOptimizer)
+    x._postprocess_feasibility = true
+    return
+end

    Construct the JuMP Model and Optimize

    Now, we'll tell EAGO to use our custom/extended solver, set up the main JuMP model, and solve it with our custom solver. 

    factory = () -> EAGO.Optimizer(SubSolvers(; t = αBB_Convex() ))
+m = JuMP.Model(optimizer_with_attributes(factory,
+                                "relative_tolerance" => 1e-3,
+                                "verbosity" => 1,
+                                "output_iterations" => 1, 
+                                "branch_variable" => Bool[true; true],
+                                ))
+Qf, cf, Qg1, cg1, Qg2, cg2 = QCQP_setup()   # Get QCQP data
+xL = [-3.0; -5.0]                           # Lower bounds on x
+xU = [1.0; 2.0]                             # Upper bounds on x
+@variable(m, xL[i] <= x[i=1:2] <= xU[i])
+
+# Define objective and constraints
+@objective(m, Min, 1/2*x'*Qf*x + cf'*x)
+@constraint(m, 1/2*x'*Qg1*x + cg1'*x <= 0.0)
+@constraint(m, 1/2*x'*Qg2*x + cg2'*x <= 0.0)
+
+# Solve the problem
+@time optimize!(m)

    Retrieve Results

    We then recover the objective value, the solution values, and termination status codes using standard JuMP syntax.

    println("x1* = ", JuMP.value(x[1]), " x2* = ",
+         JuMP.value(x[2])," f* = ",JuMP.objective_value(m))
+TermStatus = JuMP.termination_status(m)
+PrimStatus = JuMP.primal_status(m)
+println("Algorithm terminated with a status of $TermStatus and result code of $PrimStatus")

    Solving an ANN to Optimality in EAGO

    In [1, 2], a surrogate artificial neural network (ANN) model of bioreactor productivity was constructed by fitting results from computationally expensive computational fluid dynamics (CFD) simulations. The authors then optimized this surrogate model to obtain ideal processing conditions. The optimization problem is given by:

    \[\begin{aligned} +\max_{\mathbf x \in X} B_{2} + \sum_{r = 1}^{3} W_{2,r} \frac{2}{1 + \exp (-2y_{r} + B_{1,r})} \; \; {\rm where} \; \; y_{r} = \sum_{i = 1}^{8} W_{1,ir} x_{i} +\end{aligned}\]

    Input Parameters

    In the first block, we input parameters values supplied in the paper for $W_1$, $W_2$, $B_1$, and $B_2$ into Julia as simple array objects. We also input bounds for the variables which are used to scale the values obtained from optimization from $[-1, 1]$ back into the design values.

    Construct the JuMP Model and Optimize

    We now formulate the problem using standard JuMP [3] syntax and optimize it. Note that we are using the @NLexpression macro to handle the summation term to keep the code visually simple, but this could be placed directly in the @NLobjective macro instead.

    # Model construction
+model = Model(optimizer_with_attributes(EAGO.Optimizer, "absolute_tolerance" => 0.001))
+@variable(model, -1.0 <= x[i=1:8] <= 1.0)
+@NLexpression(model, y[r=1:3], sum(W1[r,i]*x[i] for i in 1:8))
+@NLobjective(model, Max, B2 + sum(W2[r]*(2.0/(1 + exp(-2.0*y[r] + B1[r]))) for r=1:3))
+
+# Solve the model
+optimize!(model)

    Retrieve Results

    We then recover the objective value, the solution values, and termination status codes using standard JuMP syntax. The optimal value and solution values are then rescaled using the variable bounds to obtain their physical interpretations.

    # Access calculated values
+fval = JuMP.objective_value(model)
+xsol = JuMP.value.(x)
+status_term = JuMP.termination_status(model)
+status_prim = JuMP.primal_status(model)
+println("EAGO terminated with a status of $status_term and a result code of $status_prim.")
+println("The optimal value is: $(round(fval, digits=5)).")
+println("The solution found is $(round.(xsol, digits=3)).")
+println(" ")
+
+# Rescale values back to physical space
+rescaled_fval = ((fval + 1.0)/2.0)*0.07
+rescaled_xsol = ((xsol .+ 1.0)./2.0).*(xUBD - xLBD) .+ xLBD
+println("Rescaled optimal value and solution values:")
+println("The rescaled optimal value is: $(round(rescaled_fval, digits=4))")
+println("The rescaled solution is $(round.(rescaled_xsol, digits=3)).")

    Using EAGO's Basic Optimizer With User-Defined Subroutines

    In this section, we construct an optimizer that uses EAGO's basic NLP solution routine with user-defined lower and upper-bounding problems. The Optimizer structure supplies a number of parameters and stored structures that advanced users may find useful for constructing specialized solution routines.

    In this example, we'll forgo extensive integration into the Optimizer and simply replace the lower and upper-bounding problems to construct a B&B routine that solves the following problem to global optimality using bounds obtained from interval arithmetic:

    \[\begin{aligned} +& \min_{\mathbf x \in X} \; \; \sin(x_{1}) x_{2}^{2} - \cos(x_{3}) / x_{4} \\ +& X = [-10, 10] \times [-1, 1] \times [-10, 10] \times [2, 20]. +\end{aligned}\]

    We begin by importing EAGO, IntervalArithmetic [1], and JuMP [2].

    using EAGO, IntervalArithmetic, JuMP

    We now define the IntervalExt struct as a subtype of the ExtensionType.

    struct IntervalExt <: EAGO.ExtensionType end

    Define a Custom Lower-Bounding Problem

    A valid lower bound is obtained from the lower bound of the natural interval extension using the IntervalArithmetic.jl [1] package. The LowerProblem is dispatched using the new IntervalExt structure and the GlobalOptimizer structure, computes the bound using interval arithmetic, and stores the results to the appropriate field of the GlobalOptimizer. Note that the problem is unconstrained on the domain so we can assume it is always feasible. Further, since the interval bound is constrained along the entire domain associated with a node, no additional cuts will be beneficial and thus we've disabled them using the _cut_add_flag field.

    import EAGO: lower_problem!
+function lower_problem!(t::IntervalExt, x::EAGO.GlobalOptimizer)
+    # Retrieve bounds at current node
+    n = x._current_node
+    lower = n.lower_variable_bounds
+    upper = n.upper_variable_bounds
+    
+    # Define X for the node and compute the interval extension
+    x_value = Interval.(lower, upper)
+    F = sin(x_value[1])*x_value[2]^2 - cos(x_value[3])/x_value[4]
+    x._lower_objective_value = F.lo
+    x._lower_solution = IntervalArithmetic.mid.(x_value)
+    x._lower_feasibility = true
+    x._cut_add_flag = false
+    
+    return
+end

    Define a Custom Upper-Bounding Problem

    Since the problem is unconstrained, any feasible point represents a valid upper bound. Thus, if we arbitrarily evaluate the function at the midpoint, we obtain a valid upper bound. This function constructs an upper bound in this manner then stores the results to the appropriate field of the GlobalOptimizer.

    import EAGO.upper_problem!
+function EAGO.upper_problem!(t::IntervalExt, x::EAGO.GlobalOptimizer)
+    # Retrieve bounds at current node
+    n = x._current_node
+    lower = n.lower_variable_bounds
+    upper = n.upper_variable_bounds
+    
+    # Compute midpoint value and evaluate at that point
+    x_value = 0.5*(upper + lower)
+    f_val = sin(x_value[1])*x_value[2]^2-cos(x_value[3])/x_value[4]
+    x._upper_objective_value = f_val
+    x._upper_solution = x_value
+    x._upper_feasibility = true
+    
+    return
+end

    Disable Unnecessary Routines

    It is entirely possible to disable domain reduction by manipulating keyword arguments supplied to the optimizer. However, for simplicity's sake we'll simply overload the default preprocessing and postprocessing methods and indicate that there are no conditions under which EAGO should cut the node.

    import EAGO: preprocess!, postprocess!, cut_condition
+function EAGO.preprocess!(t::IntervalExt, x::EAGO.GlobalOptimizer)
+    x._preprocess_feasibility = true
+    return
+end
+function EAGO.postprocess!(t::IntervalExt, x::EAGO.GlobalOptimizer)
+    x._postprocess_feasibility = true
+    return
+end
+EAGO.cut_condition(t::IntervalExt, x::EAGO.GlobalOptimizer) = false

    Construct the JuMP Model and Optimize

    We now add our optimizer to a JuMP [2] model, provide variable bounds, and optimize.

    # Create a factory that specifies the interval extension in EAGO's SubSolver
+factory = () -> EAGO.Optimizer(SubSolvers(; t = IntervalExt()))
+
+# Create a JuMP model using the factory, and with the absolute tolerance set by keyword argument
+m = Model(optimizer_with_attributes(factory,
+                    "absolute_tolerance" => 0.001
+        ))
+
+# Add variables, bounds, and the objective function
+x_L = [-10.0, -1.0, -10.0, 2.0]
+x_U = [10.0, 1.0, 10.0, 20.0]
+@variable(m, x_L[i] <= x[i=1:4] <= x_U[i])
+@NLobjective(m, Min, sin(x[1])*x[2]^2 - cos(x[3])/x[4])
+
+# Perform the optimization
+optimize!(m)

    Retrieve Results

    The objective value, solution, termination status, and primal status can then be accessed via the standard JuMP interface.

    fval = JuMP.objective_value(m)
+xsol = JuMP.value.(x)
+status_term = JuMP.termination_status(m)
+status_prim = JuMP.primal_status(m)
+
+println("EAGO terminated with a status of $status_term and a result code of $status_prim")
+println("The optimal value is: $(round(fval, digits=3)), the solution found is $(round.(xsol, digits=4)).")

    Advice for More Advanced Constructions

    The default lower_problem! and upper_problem! should be used as templates for error handling and retrieving information from MOI models.

    Essentially all of EAGO's subroutines stored to a field in the Optimizer structure can be reset as user-defined functions.

    Customizing EAGO to Solve a Quasiconvex Problem

    In this example, we'll adapt EAGO to implement the bisection-based algorithm used to solve a quasiconvex optimization problem presented in [1]:

    \[\begin{aligned} +f^{*} = & \min_{\mathbf y \in Y} f(\mathbf y) \\ +{\rm s.t.} \; \; & \sum_{i = 1}^{5} i \cdot y_{i} - 5 = 0 \\ +& \sum_{i = 1}^{5} y_{i}^{2} - 0.5 \pi \leq 0 \\ +& -\bigg(\frac{1}{2} y_{1}^{2} + \frac{1}{2} y_{2}^{2} + 2 y_{1} y_{2} + 4 y_{1} y_{3} + 2 y_{2} y_{3} \bigg) \leq 0 \\ +& -y_{1}^{2} - 6 y_{1} y_{2} - 2 y_{2}^{2} + \cos (y_{1}) + \pi \leq 0 \\ +& Y = [0, 5]^{5} +\end{aligned}\]

    where

    \[\begin{aligned} +f(\mathbf y) = -\frac{\ln ((5 + y_{1})^{2} + \sum_{i = 1}^{5} y_{i})}{1 + \sum_{i = 1}^{5} y_{i}^{2}}. +\end{aligned}\]

    Interval analysis shows that the objective value is bounded by the interval $F$ such that $f^{*} \in F = [f^{L}, f^{U}] = [-5, 0]$. Introducing an auxiliary variable $t \in T = F$ allows the problem to be formulated as:

    \[\begin{aligned} +t^{*} = & \min_{\mathbf y \in Y, t \in T} t \\ +{\rm s.t.} \; \; & (24) - (27) \\ +& f(\mathbf y) - t \leq 0 \\ +& Y = [0,5]^{2}, \; \; T = [-5,0]. +\end{aligned}\]

    Let $\phi_{\tau}(\mathbf y) = f(\mathbf y) - \tau$ such that $\tau = (t^{L} + t^{U})/2$. We solve for $\mathbf y$ subject to constraints $(24) - (27)$ where $\phi_{\tau} (\mathbf y) \leq 0$. If this is feasible, $t^{*} \in [t^{L},\tau]$, else $t^{*} \in [τ, t^{U}]$. The interval containing $t^{*}$ is kept and the other is fathomed. This manner of bisection is repeated until an interval containing a feasible solution with a width of at most $\epsilon$ is located [2].

    Customizing EAGO's Script

    First, the preprocessing step, upper problem, and postprocessing routines are short-circuited as only a single optimization problem needs to be solved at each iteration.

    using MathOptInterface, EAGO, JuMP
+import EAGO: Optimizer, GlobalOptimizer
+
+struct QuasiConvex <: EAGO.ExtensionType end
+import EAGO: preprocess!, upper_problem!, postprocess!
+function EAGO.preprocess!(t::QuasiConvex, x::GlobalOptimizer)
+    x._preprocess_feasibility = true
+end
+function EAGO.upper_problem!(t::QuasiConvex, x::GlobalOptimizer)
+    x._upper_feasibility = true
+end
+function EAGO.postprocess!(t::QuasiConvex, x::GlobalOptimizer)
+    x._postprocess_feasibility = true
+end

    Next, we specify that only an absolute tolerance should be checked for convergence and termination.

    import EAGO: convergence_check, termination_check
+function EAGO.convergence_check(t::QuasiConvex, x::GlobalOptimizer)
+    gap = (x._upper_objective_value - x._lower_objective_value)
+    return (gap <= x._parameters.absolute_tolerance)
+end
+function EAGO.termination_check(t::QuasiConvex, x::GlobalOptimizer)
+    flag = EAGO.convergence_check(t, x)
+    if flag
+        x._end_state = EAGO.GS_OPTIMAL
+        x._termination_status_code = MathOptInterface.OPTIMAL
+        x._result_status_code = MathOptInterface.FEASIBLE_POINT
+    end
+    return flag
+end

    We then indicate that only the sixth variable, representing $t$, should be branched on. Since we will apply our knowledge about which $t^{*}$ should be kept in the lower problem definition, we also short-circuit the EAGO.repeat_check function here to tell EAGO not to branch this node, but instead to repeatedly evaluate it.

    import EAGO: repeat_check
+branch_variable = [i == 6 for i=1:6]
+EAGO.repeat_check(t::QuasiConvex, x::GlobalOptimizer) = true

    In the lower problem, we then specify that the problem is to be solved locally for a fixed $t$ value. The objective value is then updated and the problem is contracted in order to discard the region which is known to not contain the optimal value.

    import EAGO: lower_problem!
+function EAGO.lower_problem!(t::QuasiConvex, x::GlobalOptimizer)
+    y = x._current_node
+    indx = x._sol_to_branch_map[6]
+    lower = y.lower_variable_bounds[indx]
+    upper = y.upper_variable_bounds[indx]
+    midy = (lower + upper)/2.0
+    y.lower_variable_bounds[indx] = midy
+    y.upper_variable_bounds[indx] = midy
+    EAGO.solve_local_nlp!(x)
+    feas = x._upper_feasibility
+    y.lower_variable_bounds[indx] = feas ? lower : midy
+    y.upper_variable_bounds[indx] = feas ? midy : upper
+    x._lower_objective_value = y.lower_variable_bounds[indx]
+    x._upper_objective_value = y.upper_variable_bounds[indx]
+    x._lower_feasibility = true
+    return
+end

    We now define the optimizer factory to extend the core EAGO optimizer for this special problem. The SubSolvers constructor is used to set the extension type (t), as well as the relaxed optimizer (r) and upper-bounding optimizer (u), if necessary. In this case, we will use the default solvers and only set the extension type.

    factory = () -> Optimizer(SubSolvers(; t = QuasiConvex()))

    Construct the JuMP Model and Optimize

    We now build the JuMP [3] model representing this problem, solve it, and retrieve the solution.

    opt = optimizer_with_attributes(factory, 
+                                "absolute_tolerance" => 1E-8, 
+                                "branch_variable" => branch_variable,
+                                "iteration_limit" => 1000)
+m = Model(opt)
+@variable(m, ((i<6) ? 0.0 : -5.0) <= y[i=1:6] <= ((i<6) ? 5.0 : 0.0))
+@constraint(m, sum(i*y[i] for i=1:5) - 5.0 == 0.0)
+@constraint(m, sum(y[i]^2 for i=1:5) - 0.5*pi^2 <= 0.0)
+@expression(m, expr1, 2.0*y[1]*y[2] + 4.0*y[1]*y[3] + 2.0*y[2]*y[3])
+@constraint(m, -(0.5*y[1]^2 + 0.5*y[2]^2 + y[3]^2 + expr1) <= 0.0)
+@NLexpression(m, expr2, log((5.0 + y[1])^2 + sum(y[i] for i=1:5)))
+@NLconstraint(m, -y[1]^2 - 6.0*y[1]*y[2] - 2.0*y[2]^2 + cos(y[1]) + pi <= 0.0)
+@NLconstraint(m, -expr2/(1.0 + sum(y[i]^2 for i=1:5)) - y[6] <= 0.0)
+@objective(m, Min, y[6])
+
+JuMP.optimize!(m)

    Retrieve Results

    We then recover the solution values and the objective value using standard JuMP syntax.

    solution = JuMP.value.(y[1:5])
+global_obj_value = JuMP.value.(y[6])
+print("Global solution at y*=$solution with a value of f*=$global_obj_value")

    If you would like to contribute, contact us.

    Overview

    EAGO is a global and robust optimization platform based on McCormick relaxations. It contains the first widely accessible global optimization routine based on generalized McCormick relaxations. With the exception of calls to local solvers and linear algebra routines, EAGO is written entirely in native Julia. The solver is flexibly arranged so the end user can easily customize low-level routines.

    Installing EAGO

    EAGO is a registered Julia package and it can be installed using the Julia package manager. From the Julia REPL, type ] to enter the Package manager (Pkg) mode and run the following command:

    pkg> add EAGO

    Currently, EAGO is compatible with version 1.12 of JuMP. This allows a replication of some of the internal features shared by EAGO and JuMP's automatic differentiation scheme, e.g., generation of Wengert Tapes, passing evaluators between JuMP and EAGO, etc.

    pkg> add JuMP

    EAGO v0.8.1 is the current tagged version and requires Julia 1.6+ for full functionality (however Julia 1.0+ versions support partial functionality). Use with version 1.8 is recommended as the majority of in-house testing has occurred using this version of Julia. The user is directed to the High-Performance Configuration for instructions on how to install a high performance version of EAGO (rather than the basic entirely open-source version). If any issues are encountered when loading EAGO (or when using it), please submit an issue using the GitHub issue tracker.

    EAGO - Easy Advanced Global Optimization

    EAGO is an open-source development environment for robust and global optimization in Julia. See the full README for more information.

    PSOR LabCurrent VersionBuild StatusDocumentation
    Build Status codecov

    EAGO is a deterministic global optimizer designed to address a wide variety of optimization problems, emphasizing nonlinear programs (NLPs), by propagating McCormick relaxations along the factorable structure of each expression in the NLP. Most operators supported by modern automatic differentiation (AD) packages are supported by EAGO and a number utilities for sanitizing native Julia code and generating relaxations on a wide variety of user-defined functions have been included. Currently, EAGO supports problems that have a priori variable bounds defined and have differentiable constraints. That is, problems should be specified in the generic form below:

    $

    \begin{align} f^{\} = & \min{\mathbf y \in Y \subset \mathbb R^{n{y}}} f(\mathbf y) \ +{\rm s.t.} \;\; & \mathbf h(\mathbf y) = \mathbf 0 \ +& \mathbf g(\mathbf y) \leq \mathbf 0 \ +& Y = [\mathbf y^{\mathbf L}, \mathbf y^{\mathbf U}] \in \mathbb{IR}^{n} \ +& \qquad \mathbf y^{\mathbf L}, \mathbf y^{\mathbf U} \in \mathbb R^{n} \end{align*} $

    For each nonlinear term, EAGO makes use of factorable representations to construct bounds and relaxations. In the case of $f(x) = x (x - 5) \sin(x)$, a list is generated and rules for constructing McCormick relaxations are used to formulate relaxations in the original decision space, $X$ [1]:

    • \[v_{1} = x\]

    • \[v_{2} = v_{1} - 5\]

    • \[v_{3} = \sin(v_{1})\]

    • \[v_{4} = v_{1} v_{2}\]

    • \[v_{5} = v_{4} v_{3}\]

    • \[f(x) = v_{5}\]

    <p align="center"> <img src="https://github.com/PSORLab/EAGO.jl/blob/master/docs/src/mccormick/Figure_1.png" width="60%" height="60%">

    Either these original relaxations, differentiable McCormick relaxations [2], or affine relaxations thereof can be used to construct relaxations of optimization problems useful in branch and bound routines for global optimization. Utilities are included to combine these with algorithms for relaxing implicit functions [3] and forward-reverse propagation of McCormick arithmetic [4].

    \begin{align} & \max{\mathbf x \in X} 0.063 x{4} x{7} - 5.04 x{1} - 0.035 x{2} - 10 x{3} - 3.36 x{2} \ +{\rm s.t.} \;\; & x{1} (1.12 + 0.13167 x{8} - 0.00667 x{8}^{2}) + x{4} = 0 \ +& -0.001 x{4} x{9} x{6} / (98 - x{6}) + x{3} = 0 \ +& -(1.098 x{8} - 0.038 x{8}^{2}) - 0.325 x{6} + x{7} = 0 \ +& -(x{2} + x{5}) / x{1} + x{8} = 0 \ +& -x{1} + 1.22 x{4} - x{5} = 0 \ +& x{9} + 0.222 x{10} - 35.82 = 0 \ +& -3.0 x{7} + x_{10} + 133.0 = 0 \ +& X = [10, 2000] \times [0, 16000] \times [0, 120] \times [0, 5000] \ +& \qquad \times [0, 2000] \times [85, 93] \times [90,9 5] \times [3, 12] \times [1.2, 4] \times [145, 162] \end{align} $

    This model can be formulated in Julia as:

    using JuMP, EAGO
+
+# Build model using EAGO's optimizer
+m = Model(EAGO.Optimizer)
+
+# Define bounded variables
+xL = [10.0; 0.0; 0.0; 0.0; 0.0; 85.0; 90.0; 3.0; 1.2; 145.0]

+
+# Define linear constraints

+@constraint(m, e7, -3.0*x[7] + x[10] == -133.0)
+
+# Define nonlinear objective
+@NLobjective(m, Max, 0.063*x[4]*x[7] - 5.04*x[1] - 0.035*x[2] - 10*x[3] - 3.36*x[5])

    Documentation

    EAGO has numerous features: a solver accessible from JuMP/MathOptInterface (MOI), domain reduction routines, McCormick relaxations, and specialized nonconvex semi-infinite program solvers. A full description of all features can be found on the documentation website. A series of example have been provided in the documentation and in the form of Jupyter Notebooks in the separate EAGO-notebooks repository.

    A Cautionary Note on Global Optimization

    As a global optimization platform, EAGO's solvers can be used to find solutions of general nonconvex problems with a guaranteed certificate of optimality. However, global solvers suffer from the curse of dimensionality and therefore their performance is outstripped by convex/local solvers. For users interested in large-scale applications, be warned that problems generally larger than a few variables may prove challenging for certain types of global optimization problems.

    Currently Supported Operators

    The operators currently supported are listed below. The operators with a check box have been subject to a large degree of scrutiny and have been implemented for both forward and reverse McCormick relaxations (Wechsung2015). Each McCormick object is associated with a parameter T <: RelaxTag which is either NS for nonsmooth relaxations (Mitsos2009, Scott2011), MV for multivariate relaxations (Tsoukalas2014, Najman2017), or Diff for differentiable relaxations (Khan2016, Khan2018, Khan2019). Conversion between NS, MV, and Diff relax tags is not currently supported. Convex and concave envelopes are used to compute relaxations of univariate functions.

    Univariate McCormick Operators

    Arbitrarily differentiable relaxations can be constructed for the following operators:

    • Inverse (inv)
    • Logarithms (log, log2, log10)
    • Exponential Functions (exp, exp2, exp10)
    • Square Root (sqrt)
    • Absolute Value (abs)

    Both nonsmooth and Whitney-1 (once differentiable) relaxations are supported for the following operators:

    • Step Functions (step, sign)
    • Trigonometric Functions (sin, cos, tan)
    • Inverse Trigonometric Functions (asin, acos, atan)
    • Hyperbolic Functions (sinh, cosh, tanh)
    • Inverse Hyperbolic Functions (asinh, acosh, atanh)
    • Common Activation Functions (relu, leaky_relu, param_relu, sigmoid, bisigmoid, softsign, softplus, maxtanh, pentanh, gelu, elu, selu, swish)
    • Special Functions (erf)

    Bivariate McCormick Operators

    The following bivariate operators are supported for two MC objects. Both nonsmooth and Whitney-1 (once differentiable) relaxations are supported.

    • Multiplication (*)
    • Division (/)

    Arbitrarily differentiable relaxations can be constructed for the following operators:

    • Addition (+)
    • Subtraction (-)
    • Minimization (min)
    • Maximization (max)

    Common Subexpressions

    The following functions can be used in place of common subexpressions encountered in optimization and will result in improved performance (in each case, the standard McCormick composition rules are often more expansive).

    McCormick.xexpax — Function

    expax

    The expax function is defined as expax(x, a) = x*exp(a*x).

    Form defined in Najman, Jaromił, Dominik Bongartz, and Alexander Mitsos. "Relaxations of thermodynamic property and costing models in process engineering." Computers & Chemical Engineering 130 (2019): 106571.

    McCormick.arh — Function

    arh

    The arrhenius function arh is defined as arh(x) = exp(-k/x).

    McCormick.xlogx — Function

    xlogx

    The function xlogx is defined as xlogx(x) = x*log(x).

    McCormick.mm — Function
    mm(X,v,K) = v*X / (X + K)

    A Michaelis-Menten rate function.

    Bound Setting Functions

    The following functions are used to specify that known bounds on a subexpression exist and that the relaxation/interval bounds propagated should make use of this information. The utility functions can be helpful in avoiding domain violations that arise due to the overly expansive nature of composite relaxations. Improper use of these functions may lead to cases in which the resulting relaxations are empty, so the user is encouraged to use discretion.

    McCormick.positive — Function

    positive(x::MC)

    Sets the lower interval bound and the convex relaxation of x to a value of at least McCormick.MC_DOMAIN_TOL. (Sub)gradients are adjusted appropriately.

    McCormick.negative — Function

    negative(x::MC)

    Sets the upper interval bound and the concave relaxation of x to a value of at most -McCormick.MC_DOMAIN_TOL. (Sub)gradients are adjusted appropriately.

    McCormick.lower_bnd — Function

    lower_bnd(x::MC, lb::Float64)

    Sets the lower interval bound and the convex relaxation of x to a value of at least lb. (Sub)gradients are adjusted appropriately.

    McCormick.upper_bnd — Function

    upper_bnd(x::MC, ub)

    Sets the upper interval bound and the concave relaxation of x to a value of at most ub. (Sub)gradients are adjusted appropriately.

    McCormick.bnd — Function

    bnd(x::MC, lb, ub)

    Sets the lower interval bound and the convex relaxation of x to a value of at least lb. Sets the upper interval bound and the concave relaxation of x to a value of at most ub. (Sub)gradients are adjusted appropriately.

    McCormick.param_relu — Function

    param_relu

    The parametric Rectified Linear Unit activation function param_relu(x, α) = (max(x, αx) with α in [0,1].

    McCormick.maxtanh — Function

    Overview

    EAGO provides a library of McCormick relaxations in native Julia code. The EAGO optimizer supports relaxing functions using nonsmooth McCormick relaxations (Mitsos2009, Scott2011), smooth McCormick relaxations (Khan2016, Khan2018, Khan2019), and multi-variant McCormick relaxations (Tsoukalas2014; a variant of subgradient-based interval refinement (Najman2017)). For functions with arbitrarily differentiable relaxations, the differentiable constant μ can be modified by adjusting a constant value in the package. Additionally, validated and nonvalidated interval bounds are supported via IntervalArithmetic.jl which is reexported. The basic McCormick operator and reverse McCormick operator (Wechsung2015) libraries are included in two dependent subpackages which can loaded and used independently:

    NaN Numerics

    When a relaxation is computed at an undefined point or over an unbounded domain, the resulting relaxation is defined as "not a number" (NaN) rather than throwing an error. This allows algorithms to check for these cases without resorting to try-catch statements. Moreover, when the interval domain is extensive enough to cause a domain violation, an x::MC structure is returned that satisfies isnan(x) === true.

    If we instead use the constructor xMC = MC{1,Diff}(x,Intv,1) in the above code and re-plot,  we arrive at the following graph. Note that these relaxations are differentiable, but not as tight as the nonsmooth relaxations.

    This can readily be extended to multivariate functions, for example, f(x,y) = (4 - 2.1x^2 + (x^4)/6)x^2 + xy + (-4 + 4y^2)y^2:
    using McCormick
+Iv = fMC.Intv            # Retrieve interval bounds of f(x) on Intv

    EAGO's Branch and Bound Routine

    This component is meant to provide a flexible framework for implementing spatial branch-and-bound based optimization routines in Julia. All components of the branch-and-bound routine can be customized by the individual user: lower bounding problem, upper bounding problem.

By default, EAGO applies Kelley's algorithm (from Kelley Jr., J.E.:  The cutting-plane method for solving convex programs. J. Soc. Ind. Appl. Math. 8(4),  703 to 712 (1960)) while cut_condition(m) returns true then activates the integrality constraints of the relaxed problems and solves the resulting MILP relaxation. results are stored to the _lower_solution, _lower_termination_status, _lower_primal_status, _lower_dual_status, _lower_objective_value, and _lower_feasibility. Further, lower and upper variable duals are stored _lower_lvd and _lower_uvd, respectively, for use in duality based bound tightening.

    optimize_hook!(t::ExtensionType, m::Optimizer)

    Provide a hook for extensions to EAGO.

    The user-defined extension of optimize_hook! is used in EAGO's overloading of MOI.optimize! (see EAGO.jl/src/eago_optimizer/optimize/optimize.jl). Without the optimize_hook! specified, EAGO will run initial_parse!, parse_classify_problem!, and then optimize! using the parsed problem type. The user-specified optimize_hook! should thus take the new extension and Optimizer as inputs and will execute when the user writes optimize!(model).

    Example

    Here, optimize_hook! is used to bypass EAGO's problem parsing and treat every problem using its branch-and-bound routine. This is done in this example by telling EAGO to treat the problem as a mixed integer nonconvex problem, which normally dispatches to branch-and-bound.

    struct MyNewExtension <: EAGO.ExtensionType end
+import EAGO: optimize_hook!
+function EAGO.optimize_hook!(t::MyNewExtension, m::Optimizer)
+    initial_parse!(m)
+    optimize!(EAGO.MINCVX(), m)
+end

    The same functionality could be accomplished by setting the EAGOParameter field force_global_solve to be true.

    High-Performance Configuration

    LP Solver Selection

    By default, EAGO uses GLPK for solving linear subproblems introduced. Using a commercial linear solver is highly recommended such as Gurobi, CPLEX, or XPRESS is highly recommended. Both Gurobi and CPLEX are free for academics and installation information can be found on the Gurobi website and the IBM website, respectively.

    A non-default LP solver can then be selected by the user via a series of keyword argument inputs as illustrated in the code snippet below. The relaxed_optimizer contains an instance optimizer with valid relaxations that are made at the root node and is updated with affine relaxations in place.

    # Create opt EAGO Optimizer with Gurobi as a lower subsolver
-subsolver_config = SubSolvers(relaxed_optimizer = Gurobi.Optimizer(OutputFlag=0))
-eago_factory = () -> EAGO.Optimizer(subsolvers = subsolver_config)
-m = Model(eago_factory)

    Rounding Mode

    The IntervalArithmetic.jl package supports a number of different directed rounding modes. The default directed rounding mode is :tight. It is recommended that the user specify that :accurate directed rounding mode be used as it may results in a significant performance improvement. Setting a rounding mode can requires the redefinition of a number of functions. As a result, this should only be done at the top-level by the user (rather than by using keyword arguments). To set the rounding mode to :accurate using the following syntax when loading the EAGO package initially:

    EAGO Specific Functions and Operators

    EAGO supports a number of functions and operators that for which specialized relaxation routines are available. These can be registered and added to a JuMP model using the function

    EAGO.register_eago_operators! — Method

    registereagooperators!

    Registers all nonstandard nonlinear terms available in EAGO in a JuMP. Uses of these is generally preferable in EAGO as the relaxations EAGO will generate will usually be tighter (speeding up convergence time). Note that this will work can be used by other nonlinear solvers (Ipopt for instance).

    Extending EAGO

    Functionality has been included that allows for extension's to EAGO's optimizer to readily be defined. This can be done in two ways first defining a new structure which is a subtype of EAGO.ExtensionType and overloading methods associated with this new structure. An instance of this new structure is provided to the EAGO.Optimizer using the ext_type keyword. This results in EAGO now dispatch to the new methods rather than the generally defined methods for the parent type. For a complete example, the reader is directed to the interval bounding example and quasiconvex example. Alternatively, the user can overload the optimize_hook! for this subtype which will entirely circumvent the default global solution routine. Additional information can be stored in the ext field of EAGO. In order to allow for compatibility between packages the user is encouraged to append their extension name to the start of each variable name (e.g. newext_newdata).

    EAGO Specific Functions and Operators

    EAGO supports a number of functions and operators that for which specialized relaxation routines are available. These can be registered and added to a JuMP model using the function:

    EAGO.register_eago_operators! — Method

    registereagooperators!

    Registers all nonstandard nonlinear terms available in EAGO in a JuMP. Uses of these is generally preferable in EAGO as the relaxations EAGO will generate will usually be tighter (speeding up convergence time). Note that this will work can be used by other nonlinear solvers (Ipopt for instance).

    Extending EAGO

    Functionality has been included that allows for extensions to EAGO's Optimizer to be readily defined. This can be done in two ways first defining a new structure which is a subtype of ExtensionType and overloading methods associated with this new structure. An instance of this new structure is provided to the Optimizer using the ext_type keyword. This results in EAGO now dispatch to the new methods rather than the generally defined methods for the parent type. For a complete example, the reader is directed to the interval bounding example and the quasiconvex example. Alternatively, the user can overload the optimize_hook! for this subtype which will entirely circumvent the default global solution routine. Additional information can be stored in the ext field of the Optimizer. In order to allow for compatibility between packages the user is encouraged to append their extension name to the start of each variable name (e.g. newext_newdata).

    Advanced-Use Example 2

    This example is also provided here as a Jupyter Notebook.

    An $\alpha$BB Example for a QCQP.

    In this example, we will demonstrate the use of a user-defined lower-bounding problem that uses $\alpha$BB convex relaxations. In this example, we wish to solve the nonconvex quadratically constrained quadratic program (QCQP):

    \[\begin{aligned} -&\min_{\mathbf x\in\mathbb R^2}\frac{1}{2}\mathbf x^{\rm T}\mathbf Q_f\mathbf x+\mathbf c_f^{\rm T}\mathbf x\\ -{\rm s.t.}\;\;&g_1(\mathbf x)=\frac{1}{2}\mathbf x^{\rm T}\mathbf Q_{g_1}\mathbf x+\mathbf c_{g_1}^{\rm T}\mathbf x\le 0\\ -&g_2(\mathbf x)=\frac{1}{2}\mathbf x^{\rm T}\mathbf Q_{g_2}\mathbf x+\mathbf c_{g_2}^{\rm T}\mathbf x\le 0\\ -\end{aligned}\]

    with $\mathbf Q_i\in\mathbb R^{2\times 2}$ not positive semidefinite for any $i$.

    using JuMP, EAGO, Ipopt, LinearAlgebra

    Custom Function Definitions

    For convenience, we'll define the following function that returns all the problem data $\mathbf Q_i$ and $\mathbf c_i$.

    function QCQP_setup()
-
-    Qf = [3. 3/2.;3/2. -5.]
-    cf = [3.;2.]
-
-    Qg1 = [-2. 5.;5. -2.]
-    cg1 = [1.;3.]
-
-    Qg2 = [-6. 3.;3. 2.]
-    cg2 = [2.;1.]
-    
-    return Qf,cf,Qg1,cg1,Qg2,cg2
-end

    The next function we'll define will take as input data for a particular quadratic function and the interval bounds on the decision variables, and construct an $\alpha$BB convex relaxation of that function. Since we're solving a QCQP, we'll use the eigvals function to directly compute the eigenvalues of the input $\mathbf Q_i$ matrix.

    function αBB_relax(Q::Matrix{T}, c::Vector{T}, xL::Vector{T}, xU::Vector{T}, x::Real...) where {T<:Float64}
-    α = max(0,-minimum(eigvals(Q))/2)
-    y = [x[1];x[2]]
-    cv = 1/2*y'*Q*y+c'*y+α*(xL-y)'*(xU-y)
-    return cv
-end

    Redefine the Lower-Bounding Problem

    The following code first defines our EAGO extension (custom version) struct and then it redefines the lower-bounding problem as our own version. That is, when we call this customized version of EAGO to solve the problem, it'll deploy this version of the lower-bounding problem instead of the default version. 

    import EAGO: Optimizer, GlobalOptimizer

-struct αBB_Convex <: EAGO.ExtensionType end
-import EAGO: lower_problem!
-function EAGO.lower_problem!(t::αBB_Convex, opt::GlobalOptimizer)

-    # Get bounds on active node for calculating relaxations
-    xL = n.lower_variable_bounds[1:2]
-    xU = n.upper_variable_bounds[1:2]
-    # Get the problem data

-    g1cv(x...) = αBB_relax(Qg1,cg1,xL,xU,x...)
-    g2cv(x...) = αBB_relax(Qg2,cg2,xL,xU,x...)

-    @NLconstraint(mL,g1cv(x[1],x[2])<=0.)
-    @NLconstraint(mL,g2cv(x[1],x[2])<=0.)
-    
-    # Solve the relaxed problem

-    tstatus = MOI.get(mL, MOI.TerminationStatus())
-    pstatus = MOI.get(mL, MOI.PrimalStatus())
-
-    solution = JuMP.value.(x)
-    # Interpret status codes for branch-and-bound
-    if EAGO.local_problem_status(tstatus, pstatus) == EAGO.LRS_FEASIBLE
-        opt._lower_objective_value = JuMP.objective_value(mL) 
-        opt._lower_solution[1:length(solution)] = solution
-        opt._lower_feasibility = true
-        opt._cut_add_flag = false
-    else
-        opt._lower_feasibility = false
-        opt._lower_objective_value = -Inf
-        opt._cut_add_flag = false
-    end
-    return
-end
    Note

    By default, EAGO solves the epigraph reformulation of your original problem, which increases the original problem dimensionality by +1 with the introduction of an auxiliary variable. When defining custom routines (such as the lower-bounding problem here) that are intended to work nicely with default EAGO routines (such as preprocessing), the user must account for the new dimensionality of the problem. In the code above, we wish to access the information of the specific B&B node and define an optimization problem based on that information. However, in this example, the node has information for 3 variables (the original 2 plus 1 for the auxiliary variable appended to the original variable vector) as $(x_1,x_2,\eta)$. The lower-bounding problem was defined to optimize the relaxed problem with respect to the original 2 decision variables. When storing the results of this subproblem to the current B&B node, it is important to take care to store the information at the appropriate indices and not inadvertently redefine the problem dimensionality (i.e., by simply storing the optimization solution as the lower_solution of the current node). For problems that are defined to only branch on a subset of the original variables, the optimizer has a member _sol_to_branch_map that carries the mapping between the indices of the original variables to those of the variables being branched on. See the Advanced-Use Example 1 to see how this is done.

    (Optional) Turn Off Processing Routines

    Turn off preprocessing routines if you don't want to use them as defined in EAGO. 

    import EAGO: preprocess!
-function EAGO.preprocess!(t::αBB_Convex, x::GlobalOptimizer)
-    x._preprocess_feasibility = true
-    return
-end

    Turn off postprocessing routines if you don't want to use them as defined in EAGO. 

    import EAGO: postprocess!
-function EAGO.postprocess!(t::αBB_Convex, x::GlobalOptimizer)
-    x._postprocess_feasibility = true
-    return
-end

    Construct the JuMP Model and Optimize

    Now, we'll tell EAGO to use our custom/extended solver, set up the main JuMP model, and solve it with our custom solver. 

    factory = () -> EAGO.Optimizer(SubSolvers(; t=αBB_Convex() ))
-m = JuMP.Model(optimizer_with_attributes(factory,
-                                "relative_tolerance" => 1e-3,
-                                "verbosity" => 1,
-                                "output_iterations" => 1, 
-                                "branch_variable" => Bool[true; true],
-                                ))
-Qf,cf,Qg1,cg1,Qg2,cg2=QCQP_setup()  # Get QCQP data
-xL = [-3.;-5.]                      # Lower bounds on x
-xU = [1.; 2]                        # Upper bounds on x
-@variable(m, xL[i] <= x[i=1:2] <= xU[i])
-
-# Define objective and constraints
-@objective(m,Min,1/2*x'*Qf*x+cf'*x)
-@constraint(m,1/2*x'*Qg1*x+cg1'*x<=0.)
-@constraint(m,1/2*x'*Qg2*x+cg2'*x<=0.)
-
-# Solve the problem
-@time optimize!(m)

    Retrieve Results

    We then recover the objective value, the solution value, and termination status codes using standard JuMP syntax.

    println("x1* = ", JuMP.value(x[1]), " x2* = ",
-         JuMP.value(x[2])," f* = ",JuMP.objective_value(m))
-TermStatus = JuMP.termination_status(m)
-PrimStatus = JuMP.primal_status(m)
-println("Algorithm terminated with a status of $TermStatus and result code of $PrimStatus")

    Solving an ANN to Optimality in EAGO

    In [1,2], a surrogate artificial neural network (ANN) model of bioreactor productivity was constructed by fitting results from computationally expensive computational fluid dynamics (CFD) simulations. The authors then optimized this surrogate model to obtain ideal processing conditions. The optimization problem is given by:

    \[\begin{aligned} -\max_{\mathbf x \in X} B_{2} + \sum_{r = 1}^{3} W_{2,r} \frac{2}{1 + \exp (-2y_{r} + B_{1,r})} \;\; \text{where} \;\; y_{r} = \sum_{i = 1}^{8} W_{1,ir} x_{i} -\end{aligned}\]

    Input Parameters

    In the first block, we input parameters values supplied in the paper for $W_1$, $W_2$, $B_1$, and $B_2$ into Julia as simple array objects. We also input bounds for the variables which are used to scale the values obtained from optimization from $[-1, 1]$ back into the design values.

    Construct the JuMP Model and Optimize

    We now formulate the problem using standard JuMP [3] syntax and optimize it. Note that we are forming an NLexpression object to handle the summation term to keep the code visually simple, but this could be placed directly in the JuMP @NLobjective expression instead.

    # Model construction
-model = Model(optimizer_with_attributes(EAGO.Optimizer, "absolute_tolerance" => 0.001))
-@variable(model, -1.0 <= x[i=1:8] <= 1.0)
-@NLexpression(model, y[r=1:3], sum(W1[r,i]*x[i] for i in 1:8))
-@NLobjective(model, Max, B2 + sum(W2[r]*(2/(1+exp(-2*y[r]+B1[r]))) for r=1:3))
-
-# Solve the model
-optimize!(model)

    Retrieve Results

    We then recover the objective value, the solution value, and termination status codes using standard JuMP syntax. The optimal value and solution values are then rescaled using the variable bounds to obtain their physical interpretations.

    # Access calculated values
-fval = JuMP.objective_value(model)
-xsol = JuMP.value.(x)
-status_term = JuMP.termination_status(model)
-status_prim = JuMP.primal_status(model)
-println("EAGO terminated with a status of $status_term and a result code of $status_prim.")
-println("The optimal value is: $(round(fval,digits=5)).")
-println("The solution found is $(round.(xsol,digits=3)).")
-println("")
-
-# Rescale values back to physical space
-rescaled_fval = ((fval+1)/2)*0.07
-rescaled_xsol = ((xsol.+1.0)./2).*(xUBD-xLBD).+xLBD

-println("The rescaled optimal value is: $(round(rescaled_fval,digits=4))")

    Customization Guidelines

    This section contains general guidelines on how the functionality of EAGO can be extended for specific use cases. Many functions in EAGO are extensible, so examples are not provided for every possible case, but some important functions are covered. If there is a use case you do not see provided here, but would like to see, please contact Robert Gottlieb.

    1) Creating an Extension

    Extensibility in EAGO is based on the EAGO.ExtensionType type. To create customized functions, the recommended method is to create a new structure, as follows:

    using EAGO
-
-struct MyNewStruct <: EAGO.ExtensionType end

    To let EAGO know that you would like to use this extension (and any functions you overload), when you create the JuMP model, declare your new type in the SubSolvers field of EAGO's optimizer as follows:

    using JuMP
-
-factory = () -> EAGO.Optimizer(SubSolvers(; t = MyNewStruct() ))
-model = Model(factory)

    The key point to note here is that the new structure is set to SubSolvers.t, which is the field that holds any user-defined extension type. Now, when EAGO calls any of its functions, it will check to see if a custom function for this new extension has been created. If so, it will use the new one; if not, it will use the default version of that function.

    2) Preprocessing

    In EAGO's branch-and-bound routine, preprocessing is performed prior to solving the lower and upper problems. By default, linear and quadratic contractor methods are performed, followed by interval constraint propagation, then optimization-based bounds tightening. An important outcome of EAGO's default preprocessing is that the _preprocess_feasibility field of the EAGO.GlobalOptimizer is set to true, unless the subproblem at the current node has been proven infeasible. Therefore, to bypass preprocessing for your own problem, you must, at a minimum, set this field to true. For example:

    import EAGO: preprocess!
-function EAGO.preprocess!(t::MyNewStruct, x::EAGO.GlobalOptimizer)
-    x._preprocess_feasibility = true
-end

    The user-defined preprocessing step can be as simple or complex as desired, but if _preprocess_feasibility is not set to true, EAGO will assume each node is infeasible.

    3) Lower Problem

    By default, EAGO applies Kelley's cutting-plane algorithm [1] to solve the lower bounding problem. This can be overloaded using the same syntax as for the other functions. Necessary changes to the EAGO.GlobalOptimizer that occur within the lower problem are changing the _lower_objective_value and _lower_feasibility fields. If the _lower_objective_value field is not changed, branch-and-bound will not update the lower bound. If _lower_feasibility is not set to true, the node will be discarded as infeasible. A minimum functional (though not useful) lower problem extension is as follows:

    import EAGO: lower_problem!
-function EAGO.lower_problem!(t::MyNewStruct, x::EAGO.GlobalOptimizer)
-    x._lower_objective_value = -Inf
-    x._lower_feasibility = true
-end

    Any arbitrarily complex lower problem can be substituted here in place of EAGO's default method, as long as these fields are updated. Note also that, although there is a separate upper problem function, if the lower problem is being replaced by an algorithm that also calculates an upper objective value, the necessary fields to update in upper_problem! can simply be updated here, and the upper_problem! can be overloaded by a function that does nothing.

    4) Upper Problem

    By default, the upper bounding problem is run on every node up to depth upper_bounding_depth, and is triggered with a probability of 0.5^(depth - upper_bounding_depth) afterwards for continuous problems. For integer problems, this approach is used in addition to running on every node up to depth upper_bounding_depth + cont_depth, with another trigger of probability 0.5^(depth - upper_bounding_depth - cont_depth). The upper_bounding_depth and cont_depth are fields of GlobalOptimizer._parameters and can be changed from their default values when the JuMP model is created, or at any time afterwards. If any of these trigger conditions are met, the default EAGO upper problem runs a local NLP solve.

    The important fields to update in the upper_problem! are the _upper_objective_value and _upper_feasibility fields. If _upper_objective_value is not updated, the upper bound in the branch-and-bound algorithm will not update and the problem will not converge. If _upper_feasibility is not set to true, then any changes made to _upper_objective_value will not be updated for each node and the problem will not converge. A minimum functional (though not useful) upper problem extension is as follows:

    import EAGO: upper_problem!
-function upper_problem!(t::MyNewStruct, x::EAGO.GlobalOptimizer)
-    x._upper_objective_value = Inf
-    x._upper_feasibility = true
-end

    This example upper problem will set the upper bound on the objective value to Inf for each node. Given that no useful information is provided here, we could also have set x_upper_feasibility to false (or equivalently, remove the line where we set it to true), and the global upper bound would never be updated.

    Note that if the _upper_objective_value is changed elsewhere, such as in the definition for the lower_problem!, the _upper_feasibility flag must be set to true. If this is not done, the change to the _upper_objective_value will be discarded.

    5) Convergence Check

    By default, EAGO checks to see if the lower and upper bounds have converged to within either the absolute or relative tolerance. This method of checking convergence may not be desired if, for example, only the absolute tolerance is relevant, and you want to ensure that the program does not end prematurely due to a relative tolerance limit being reached. The fields to check are _lower_objective_value and _upper_objective_value for the best-identified global lower and upper bounds, respectively. This function should return true if the lower and upper bounds have converged, and false otherwise. An example of how to specify that the convergence check only use the absolute tolerance is as follows:

    import EAGO: convergence_check
-function EAGO.convergence_check(t::MyNewStruct, x::EAGO.GlobalOptimizer)
-    gap = (x._upper_objective_value - x._lower_objective_value)
-    return (gap <= x._parameters.absolute_tolerance)
-end

    6) Postprocessing

    Postprocessing is the final step before a node is branched on. By default, EAGO performs duality-based bounds tightening[2] up to an iteration limit set by dbbt_depth in the GlobalOptimizer._parameters field. The important field to update in postprocessing is _postprocess_feasibility, which must be set to true for EAGO to branch on any given node. The minimum working postprocessing function is therefore:

    import EAGO: postprocess!
-function EAGO.postprocess!(t::MyNewStruct, x::EAGO.GlobalOptimizer)
-    x._postprocess_feasibility = true
-end

    If _postprocess_feasibility is not set to true, no nodes will be branched on.

    7) Termination Check

    This is the check that occurs on each iteration of the branch-and-bound algorithm that determines whether the algorithm continues or not. By default, several conditions are checked for such as the satisfaction of absolute or relative tolerances, solution infeasibility, or other specified limits. This function returns true if any of the stopping conditions have been met, and branch-and-bound should stop, and false otherwise. The important fields to update are _end_state, which takes values of EAGO.GlobalEndState, _termination_status_code, which takes values of MathOptInterface.TerminationStatusCode, and _result_status_code, which takes values of MathOptInterface.ResultStatusCode. Combined, these fields provide information about the branch-and-bound completion status and result feasibility.

    As an example, suppose we have updated the convergence_check function to only check for absolute tolerance, and based on our knowledge of the problem, this is the only condition we care about, and we know the solution will be optimal. We could then overload the termination_check function as follows:

    import EAGO: termination_check
-function EAGO.termination_check(t::MyNewStruct, x::EAGO.GlobalOptimizer)
-    flag = EAGO.convergence_check(t, x)
-    if flag
-        x._end_state = EAGO.GS_OPTIMAL
-        x._termination_status_code = MathOptInterface.OPTIMAL
-        x._result_status_code = MathOptInterface.FEASIBLE_POINT
-    end
-    return flag
-end

    Quick Start

    EAGO is a global optimizer primarily meant to be used with the JuMP algebraic modeling language. Typical use will involve installing EAGO and JuMP, creating a problem using JuMP syntax, and passing the problem to the EAGO optimizer.

    Customization

    EAGO is designed to be easily extensible. Some of the examples that follow include use cases where the standard EAGO functionality is overloaded and readily incorporated into the main optimization routine. Information on how to extend the main branch-and-bound functions (including lower and upper bounding routines) can be found in the Customization Guidelines section.

    Examples

    The following pages in this section include several representative examples of how EAGO can be used. Additional (and in some cases, shortened) examples can be found in the EAGO-notebooks repository. Examples and instructional pages in this section include:

    Advanced-Use Example 1

    This example still needs to be updated. This example is also provided here as a Jupyter Notebook.

    Customizing EAGO to Solve a Quasiconvex Problem

    In this example, we'll adapt EAGO to implement the bisection-based algorithm used to solve a quasiconvex optimization problem presented in [1]:

    Equation 1

    where:

    Equation 2

    Interval analysis shows that the objective value is bounded by the interval F such that $f^*∈ F = [f^L, f^U] = [-5, 0]$. Introducing an auxiliary variable $t∈ T = F$ allows the problem to be formulated as:

    Equation 3

    Let $ϕ_τ(y) = f(y) - τ$ such that $\tau = (t^L + t^U)/2$. We solve for $y$ subject to constraints (24)-(27) where $ϕ_τ (y) ≤ 0$. If this is feasible, $t^*∈ [t^L,τ]$, else $t^*∈ [τ, t^U]$. The interval containing $t^*$ is kept and the other is fathomed. This manner of bisection is repeated until an interval containing a feasible solution with a width of at most ϵ is located [2].

    EAGO Implementation

    In the first block, we input parameters values supplied in the paper for $W_1$, $W_2$, $B_1$, and $B_2$ into Julia as simple array objects. We also input bounds for the variables which are used to scale the values obtained from optimization from [-1, 1] back into the design values.

    using JuMP, EAGO
-
-# Weights associated with the hidden layer
-W1 = [ 0.54  -1.97  0.09  -2.14  1.01  -0.58  0.45  0.26;
-     -0.81  -0.74  0.63  -1.60 -0.56  -1.05  1.23  0.93;
-     -0.11  -0.38 -1.19   0.43  1.21   2.78 -0.06  0.40]

-W2 = [-0.91 0.11 0.52]
-
-# Bias associated with the hidden layer
-B1 = [-2.698 0.012 2.926]
-
-# Bias associated with the output layer
-B2 = -0.46

-# Variable bounds (Used to scale variables after optimization)
-xLBD = [0.623, 0.093, 0.259, 6.56, 1114,  0.013, 0.127, 0.004]
-xUBD = [5.89,  0.5,   1.0,   90,   25000, 0.149, 0.889, 0.049];

    Construct the JuMP Model and Optimize

    We now formulate the problem using standard JuMP [3] syntax and optimize it. Note that we are forming an NLexpression object to handle the summation term to keep the code visually simple, but this could be placed directly in the JuMP @NLobjective expression instead.

    # Model construction
-model = Model(optimizer_with_attributes(EAGO.Optimizer, "absolute_tolerance" => 0.001))
-@variable(model, -1.0 <= x[i=1:8] <= 1.0)
-@NLexpression(model, y[r=1:3], sum(W1[r,i]*x[i] for i in 1:8))
-@NLobjective(model, Max, B2 + sum(W2[r]*(2/(1+exp(-2*y[r]+B1[r]))) for r=1:3))
-
-# Solve the model
-optimize!(model)

    Retrieve Results

    We then recover the objective value, the solution value, and termination status codes using standard JuMP syntax. The optimal value and solution values are then rescaled using the variable bounds to obtain their physical interpretations.

    # Access calculated values
-fval = JuMP.objective_value(model)
-xsol = JuMP.value.(x)
-status_term = JuMP.termination_status(model)
-status_prim = JuMP.primal_status(model)
-println("EAGO terminated with a status of $status_term and a result code of $status_prim.")
-println("The optimal value is: $(round(fval,digits=5)).")
-println("The solution found is $(round.(xsol,digits=3)).")
-println("")
-
-# Rescale values back to physical space
-rescaled_fval = ((fval+1)/2)*0.07
-rescaled_xsol = ((xsol.+1.0)./2).*(xUBD-xLBD).+xLBD
-println("Rescaled optimal value and solution values:")
-println("The rescaled optimal value is: $(round(rescaled_fval,digits=4))")
-println("The rescaled solution is $(round.(rescaled_xsol,digits=3)).")

In the code above, we wish to access the information of the specific B&B node and define an optimization problem based on that information. However, in this example, the node has information for 3 variables (the original 2 plus 1 for the auxiliary variable appended to the original variable vector) as (x_1x_2eta). The lower-bounding problem was defined to optimize the relaxed problem with respect to the original 2 decision variables. When storing the results of this subproblem to the current B&B node, it is important to take care to store the information at the appropriate indices and not inadvertently redefine the problem dimensionality (i.e., by simply storing the optimization solution as the lower_solution of the current node). For problems that are defined to only branch on a subset of the original variables, the optimizer has a member _sol_to_branch_map that carries the mapping between the indices of the original variables to those of the variables being branched on.

In the code above, we wish to access the information of the specific B&B node and define an optimization problem based on that information. However, in this example, the node has information for 3 variables (the original 2 plus 1 for the auxiliary variable appended to the original variable vector) as (x_1 x_2 eta). The lower-bounding problem was defined to optimize the relaxed problem with respect to the original 2 decision variables. When storing the results of this subproblem to the current B&B node, it is important to take care to store the information at the appropriate indices and not inadvertently redefine the problem dimensionality (i.e., by simply storing the optimization solution as the lower_solution of the current node). For problems that are defined to only branch on a subset of the original variables, the optimizer has a member _sol_to_branch_map that carries the mapping between the indices of the original variables to those of the variables being branched on.

    Solving Semi-Infinite Programs

    Using EAGO to Solve a Semi-Infinite Program (SIP)

    Semi-infinite programming remains an active area of research. In general, the solutions of SIPs with nonconvex semi-infinite constraints of the following form are extremely challenging:

    SipProbForm

    EAGO implements three different algorithms detailed in [1,2] to determine a globally optimal solution to problems of the above form. This is accomplished using the sip_solve function which returns the optimal value, the solution, and a boolean feasibility flag. To illustrate the use of this function, a simple example is presented here which solves the problem:

    EAGO implements three different algorithms detailed in [1, 2] to determine a globally optimal solution to problems of the above form. This is accomplished using the sip_solve function which returns the optimal value, the solution, and a boolean feasibility flag.
