Effects of network topology on strategy distributions in a IPD — •Robert Mach and Frank Schweitzer — D-MTEC, ETH Center, CH-8092 Zurich

Agents are assumed to interact repeatedly in an iterated Prisoner’s Dilemma (IPD) game. The agents are endowed with a one-step memory and thus can play one of 8 different strategies. The interaction is locally restricted by a network topology, where each agent represents one node. The agents try to increase their individual payoff by adopting the strategy of their most successful partner at the end of each generation. This adaptation process leads to strategy distribution, that crucially depends on the network topology.
