为了考察演化的争当少数者博弈模型的经纪人分布在二维网格上时经纪人策略的可能分布图案,将演化的争当少数者博弈模型(EMG)建立在41x41的二维正方形网格上,考虑了单向网络和双向网络两种情况。数值模拟结果表明:无论是单向还是双向网络,节点的连接度(对于双向网络,指出度)以中等数值居多,经纪人的策略分布和连接网络结构经过演化都达到了有秩序有规律的稳态分布结构。单向的时候,一些节点组成了分块的社团类似结构,但是不会出现孤立点,度分布也比较均匀;双向的时候,社团结构并不明显,但是也会出现小的社团甚至孤立点,度分布区域大一些,但也还算是均匀。
In order to investigate possible distribution pattern of strategies of agents in EMG model distributed on a two-dimensional lattice, we put an evolutionary minority game model on 41x41 two dimensional square lattice network.We consider two situations which include unidirectional network and bidirectional network. Simulation results show no matter unidirectional or bidirectional network, the connectivity degree of nodes (for bidirectional network, it means out degree) is predominant at medium numbers. The distribution of agents' strategies and structure of network reach orderly or regular stable distribution structure after evolution. When network is unidirectional, some nodes form bulked community like structure, but there is no isolated node, degree distribution is relatively even. When network is bidirectional, there is no apparent community like structure, but there are some small communities or even isolated node, degree distribution region is somewhat larger, but still be fairly even.
