摘要
基于现实生活中的惩罚思想,结合记忆效应将惩罚机制引入个体收益,提出二维网格上的囚徒困境博弈模型。仿真结果表明与原始囚徒困境模型相比,惩罚机制极大促进了合作水平的涌现和维持。随着惩罚力度的增大或者记忆长度的缩短,合作水平得到明显提高,而且在适度的噪声环境下,合作阈值在一定程度上有利于合作行为的演化。
Based on real-life punishment ideas and combining with the memory effect,this paper puts punishment mechanism into individual income and proposes prisoner ＇s dilemma game model of twodimensional grid. The results show that comparing with the original model of the prisoner＇s dilemma,punishment mechanism greatly contributes to the emergence and maintenance of the level of cooperation.As punishment increasing or memory length shortened,the level of cooperation will be significantly improved,and under the moderate noise environment,cooperation threshold is propitious to the evolution of cooperative behaviors in a certain extent.
