 About SyDEVS
 ------------
 
-This library provides a framework for implementing complex systems analysis and simulation code in a modular/hierarchical fashion. The framework combines three modeling paradigms: [discrete event simulation](https://en.wikipedia.org/wiki/Discrete_event_simulation), [agent-based modeling](https://en.wikipedia.org/wiki/Agent-based_model), and [dataflow programming](https://en.wikipedia.org/wiki/Dataflow_programming). The discrete event simulation aspect is based on [DEVS](https://en.wikipedia.org/wiki/DEVS), a well-regarded modeling formalism involving two types of models that correspond with the library's ***atomic*** and ***composite*** nodes. The library also includes ***collection*** nodes, which extend DEVS with agent-based modeling capabilities, and ***function*** nodes, which simply compute outputs from inputs. The atomic, composite, collection, and function nodes can communicate through flow ports as part of a dataflow programming network. With the exception of function nodes, they can also communicate in a DEVS-like fashion through message ports.

 In addition to supporting multiple modeling paradigms, the SyDEVS library provides comprehensive and reusable Modern C++ implementations of multidimensional arrays, Standard International (SI) units, a multiscale time representation, and other technical computing elements.
