Repast
Encyclopedia
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
