From the developer:
Agents is a tool for simulating dynamics of selfish users in traffic networks like the Internet. Classical Game Theory has been extensively used to analyse the Internet. However, this analysis is limited to static properties of such models, e.g. equilibria, the price of anarchy, etc. We are interested in dynamical properties. Therefore we apply methods from Evolutionary Game Theory to networks.
