Evolutionary Game On Networks And The Behavior Experiment Of Asymmetric Wealth

Cooperative behaviors are ubiquitous,such as cooperation between countries and symbiosis between organisms.Individual development cannot be separated from cooperative behaviors.Development cannot be separated from cooperative behaviors.The exploration of human cooperative behavior has always been an important mission for scientists.Especially the study of cooperative behavior from the perspective of complex network provides a new perspective and method for the study of cooperative behavior evolution.Based on the basic theory of evolutionary game,this paper explores the evolution of cooperative behavior from the perspectives of simulation and behavioral experiment under the framework of complex network.This paper is divided into three parts to explore and analyze the different evolution characteristics of cooperative behavior.In the first part,this paper constructs a homogeneous grid network and conducts Monte Carlo simulation based on the public goods game.Numerical simulation results show that the neutral reward greatly improves the cooperation in the system,and can maintain this high level of cooperation.Through numerical analysis,we find that there is an indirect relationship between the promotion effect of neutral reward on cooperation and the reward factor.Larger reward factors reinforce the effect of network reciprocity,so the cooperation in the network is significantly increased.In the second part,Monte Carlo simulation of public goods game is carried out on the independent network,and asymmetric updating mechanism is introduced into the simulation model.Numerical simulation results show that the cooperation of the system is significantly reduced.The main reason for the decrease of cooperation is that the location synergy on the independent network is destroyed by asymmetric update mechanism.In the third part,the author analyzes and expounds the person behavioral economics experiment based on the prisoner's dilemma model.Traditional experiments require that the initial wealth of both sides of the game must be symmetric.In this experiment,the experimental population is divided into two types.One type of individuals has a higher initial wealth,and the other type of individuals has a lower initial wealth.Only different types of individuals can play games with each other.Through asymmetric distribution of initial wealth,the influence of unfair initial environment on cooperative behavior is revealed.It objectively reflects people's different manifestations of unfair treatment under different adverse circumstances.At the same time,this experiment reveals that the initial inequality does not affect the final wealth gap of the system.
