How to build the network of contacts : selecting the cooperative partners

Abstract

We address the problem of finding the correct agents to interact with from a general standpoint. We take the payout obtained by agents in any game with dilemma as an input to our model. Its output is a probability distribution used in the partner selection that increasingly favours cooperative agents. Our approach contrasts with others designed for specific games without concerns of generality. We show both theoretically and experimentally that the major factor affecting cooperators selecting only themselves is the agents' strategies. This result does not depend on game nature or the initial probability distribution.
