Randomness enhances cooperation: a resonance type phenomenon in evolutionary games

Abstract

We investigate the effect of randomness in both relationships and decisions on the evolution of cooperation. Simulation results show, in such randomness' presence, the system evolves to a more frequency cooperation state than in its absence. Specifically, there is an optimal amount of randomness, which can induce the highest level of cooperation. The mechanism of randomness promoting cooperation resembles a coherence-resonance-like fashion, which could be of particular interest in evolutionary game dynamics in economic, biological and social systems.
