摘　　要：研究了加权小世界网络上的演化少数者博弈模型.在该模型中引入回报机制,当经纪人通过模仿获益后,模仿者必须向被模仿者支付一定的报酬.模拟发现在某报酬下系统方差达到最小,表明此时系统的表现较好,系统资源得到更好的利用.而且随着d值的减小,系统的方差增大.This paper focuses on the system performance in an evolutionary minority game.The return mechanism has been used in this model.When the agents benefit through imitation,the imitators must pay compensation to the imitated agents.Simulation results show that system variance reaches its minimum in a certain compensation,which shows that the system behaves better in the whole.And the system variance increases with reducing d,which shows that smaller d is harmful to system.

关 键 词：演化少数者博弈 加权小世界网络 模仿
