Research On The Influence Of Individual Diversity On The Evolution Of Cooperation Based On Prisoner's Dilemma Game

According to Darwin's theory of "It is not the strongest of the species that survive,but the one most responsive to change",selfish individuals focus on maximizing their own interests in order to adapt to natural selection.Since betrayal behavior can often lead to higher personal gains than cooperative behavior,the result of rational choices aimed at maximizing personal interests is often betrayal behavior.While in fact,cooperative behavior is ubiquitous in nature and in human society.In recent years,understanding the emergence and maintenance of cooperation becomes an interesting issue and has attracted much attention from the researchers across different fields ranging from sociology to ecology,economics,and physics.In order to understand the evolution of cooperative behavior,researchers proposal many mechanisms to promote the evolution of cooperation.In this paper,we study the influence of individual heterogeneity on the evolution of cooperative behavior in the Prisoner's Dilemma game model on square lattice network,regular random networks(RRNs)and Erdos-Renyi networks(ERNs).Previous research has shown that strategy persistence and heterogeneous teaching ability both can support cooperation.In this paper,we study the influence of the heterogeneity of teaching ability and strategy persistence on cooperative evolution in the prisoner's dilemma game model.Further,we consider the impact of these two factors on system evolution under different correlation modes.The simulation results show that,compared to negative correlation,positive correlation between strategy persistence and teaching ability can greatly enhance cooperation and result in a much higher cooperation level.Furthermore,we show that the finding is robust with respect to reduced teaching ability ?,initial cooperator fraction f0,amplitude of noise K and underlying network topology.
