The files are free to download and use non-commercially, but remain the copyright (2011) of their authors. Anyone interested in producing modified versions of them or using them for commercial purposes should request permission from one of the authors. The files vary in their ease of use and robustness. Use of the files is at your own risk.

The files are categorised by book chapter. They were developed either for NetLogo (version 4.1.3) or for Excel/VBA (version 2003/XP).
