摘要
根据现实生活中经纪人交往能力不同这一现象,提出并研究了一个无标度网络上的少数者博弈模型.在该模型中,将经纪人放在无标度网络中,每个节点代表一个经纪人,经纪人交往能力的大小就用节点的度来表示.引入了可调参数α,讨论了不同可调参数α下的系统方差,结果显示α存在一个最佳值αc.当α=cα时系统方差较小,说明这时系统的表现较好,系统资源得到更好的利用.并且讨论了当α=cα时,去一方人数的标准偏差同记忆容量m的函数关系,发现在记忆容量m较小时得到的结果比原始的MG模型要好.
Agents have different communication capabilities in real life. To study this phenomena, a minority game on scale-free network is proposed. In this model, agents are set in scale-free networks, a node denotes an agent. The agent′s communication capability is expressed by the node′s degree. A tunable parameter a is introduced, the system′s SD is discussed in different parameter α, simulations shows that there is an optimal tunable parameter αc. When α=αc, the system′s standard deviation is smaller, which shows that the system behaves better in the whole, and the result of the model is better than the origin MG model for small m from the viewpoint of SD.
