This web page is an appendix to the paper Two evolutionary games: collective action and prisoner's dilemma, presented at the III CMSRA (Third International Workshop: Computational Models of Scientific Reasoning and Applications), in Buenos Aires, September 2003. The paper was published in the Proceedings of the Workshop.

Abstract: The paper presents two agent based models that simulate the evolution of cooperation. The multi-agent systems were built as computer applications and the agents, instead of rationality, have propensities to feel emotions. The interplay between the agents' personalities and the situation where they are found determine what emotions arouse and, thus partially determine their behavior.

The main purpose of this appendix is to make some files available:

The executable (for Windows) and the source code (Delphi): twogames.tar.gz or twogames.zip

Results of the simulations (SPSS and Excel formats): summary.zip

Detailed Results of the Simulations (SPSS format): They are too big to be here: 29 MB (compacted with WinZip).
