New test function to the code base
The eight-dimensional function from Dette and Pepelyshev (2010)1 is a test function used in the context of metamodeling (specifically, design of computer experiments to construct metamodels). The function reads as follows:
where$\boldsymbol{x} = \{ x_1, \ldots, x_8 \}$ is the vector of input variables modeled as an independent uniform random variable in $[0, 1]^8$ . The function is highly curved with respect to some input variables and less so with respect to some others.
