The Repast Suite Makes Modeling Easier, Faster, and More Reliable The Repast Suite is a family of advanced, free, and open source agent-based modeling and simulation platforms that have collectively been under continuous development for over 10 years: More information on Repast, as well as free downloads, can be found at: http://repast.sourceforge.net/ Repast Simphony 2.0 Beta, released on 12/3/2010, is a richly interactive and easy to learn Java-based modeling system that is designed for use on workstations and small computing clusters. Repast for High Performance Computing 1.0.1 Beta, released on 12/16/2010, is a lean and expert-focused C++-based modeling system that is designed for use on large computing clusters and supercomputers.

The Repast Suite’s New ReLogo System Combines Logo’s Time-Tested Simplicity with Repast’s Proven Power Logo: Is a widely used K-12 programming language; It was introduced in 1967; and It has been refined in over 100 variations. Logo models are developed by having turtles interact with one another and with patches. The Repast Suite offers the core Logo constructs: Turtles are the mobile agents. Patches are the fixed agents. Links connect turtles to form networks. The Observer provides overall management. The Repast Suite offers other mix-and-match options too: Repast S components can also be written using flowcharts, Java, and Groovy or imported from NetLogo Repast HPC components can be written in C++.

Using Repast Simphony is Easy Create a model: Use ReLogo, flowcharts, Groovy, or Java; or Import from NetLogo. Run your model. Activate the R wizard. Analyze your results with R! Java Flow Chart ReLogo Groovy
