Evolution of Cooperation in a One-shot Prisonerís Dilemma Based on Recognition of Trustworthy and Untrustworthy Agents

Marco Janssen
September 16, 2008

Abstract: Marco Janssen discusses an agent based model which explores the conditions under which agents will cooperate in one-shot two-player Prisonerís Dilemma games if they are able to withdraw from playing the game and can learn to recognize the trustworthiness of their opponents. When the agents display a number of symbols and they learn which symbols are important to estimate the trustworthiness of others, agents will evolve who cooperate in games in line with experimental observations. These results are robust to significant levels of mutations and errors made by the players.
