This is the original LAIS project from 2008/2009. It is a transparently multithreaded 2D agent-based simulator based on RepastJ.

We have picked up the available code and models from that time and made them public under the GPLv3 license in 2013. The code and models are partially working as this is probably not the last stable release of the time. Improvements are welcome.

You can grab the source code and models from

If you use any of the code or models please use one of the following references where applicable:
