The Recursive Porous Agent Simulation Toolkit (Repast) is a widely used free and open-source, cross-platform, agent-based modeling and simulation toolkit. Repast has multiple implementations in several languages and built-in adaptive features, such as genetic algorithms and regression.
Repast was originally developed by David Sallach, Nick Collier, Tom Howe, Michael North and others at the University of Chicago.
Features variety of agents and examples fully object oriented fully concurrent discrete event scheduler built-in simulation results logging and graphing tools allows users to dynamically access and modify agents and model at run time libraries for genetic algorithms, neural networks, etc. built-in systems dynamics modeling social network modeling tools integrated geographical information systems (GIS) support implemented in Java, C#, etc. supports Java, C#, Managed C++, Visual Basic.Net, Managed Lisp, Managed Prolog, and Python scripting, etc. is available on virtually all modern computing platforms
