The Influence Of Reputation On The Evolution Of Cooperation In Spatial Networks

Cooperation is widespread in human social groups,and exists in large and small organizations,from family organizations to national organizations.Cooperation means that individuals give play to their subjective initiative and make the benefits of the group greater than the benefits of the individual by complementing each other's advantages.Therefore,how cooperation comes into being and how to promote cooperation has been widely concerned by scholars.Evolutionary game can simulate well the issue that the individual cooperation,give prominence to the individual is to choose the ambivalence of cooperation or non-cooperation,on the other hand,the cooperation is a prerequisite for at least two people,in the big social system,individual always exists in large and small organization framework,space network is the basic organization structure provides a framework for simulation.Therefore,evolutionary game on spatial network can be used as theoretical support to study the evolution of cooperation.There are various realistic factors influencing the evolution of cooperation,and this paper focuses on the influence of reputation on the evolution of cooperation.Reputation is accumulated from past behaviors,so it can serve as an important criterion for our future decisions and a perspective to solve social dilemmas.In this paper,the relevant background and theoretical basis are described in detail.On this basis,the influence of reputation on the evolution of cooperation is explored from two different perspectives.The first Angle is the study of heterogeneity reputation is how to influence the evolution of cooperation,here,mainly from two dimensions to explore the reputation of the heterogeneity,the first dimension is by controlling the network for high reputation of the individual ratios of the effects of reputation for cooperation,found that the high reputation of individuals when network of high worsened the situation of network in full cooperation,The second dimension is to divide individuals in the network into those who pay more attention to reputation and those who pay less attention to reputation through the intensity of their attention to reputation in the decision-making process.On this basis,the proportion of individuals who pay less attention to reputation and those who pay more attention to reputation is adjusted.The results show that when the intensity of social dilemma is different,the individuals with low reputation concern can adjust the intensity of reputation concern or the proportion of individuals with high reputation concern in the network is higher,the cooperation between individuals in the network will be better.The second Angle is to take explicit punishment and implicit punishment for individuals with low reputation.It is found that appropriately increasing punishment under these two kinds of punishment is more conducive to the emergence of cooperation,and through the comparison of these two punishment mechanisms,it is found that compared with implicit punishment,adopting explicit punishment is more conducive to the cooperation between individuals in the network.
