Effects of vision field on evolution of cooperation among mobile agents

Abstract

We introduce the heterogeneous vision radius which follows powerlaw distribution into the evolutionary prisoner's dilemma game among mobile agents to study the evolution of cooperation. It is found that the cooperation level of the system presents remarkable differences when vision radius follows power-law distribution with different exponents. The cooperative agents can survive in such a system provided that the heterogeneity of vision radius is moderate and the temptation of defection is not too high. This work may be beneficial to understand cooperative behavior in biological and social systems consisted of mobile agents. © 2011 Springer-Verlag Berlin Heidelberg.
