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 (North et al. 2006) 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 (North et al. 2007)
• 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
