Cooperation of improved HK networks based on prisoner dilemma game

To model the cooperative behavior under the realistic world, we put forward a high-clustering network model with the property of adjustable power-law, and analyze the evolution of the prisoner dilemma game on this improved HK network model. Using simulation experiments, we investigate the effect of high clustering property of this network on the cooperative behavior. Extensive simulations indicate that a high value of the clustering coefficient may greatly contribute to the emergence of cooperative behavior. We also find that with the increase in the temptation parameter, the level of cooperation will decrease, but the variation range is not wide. Altogether, this evolutionary game model can promote the emergence of cooperative phenomenon by resisting the spread of the betrayal strategy.
