一种网络演化MG模型研究

A research on network evolutionary MG model

将少数者博弈模型作为描述经纪人竞争的动力学模型,并考虑了现实中存在的经纪人学习模仿机制,研究了经纪人在小世界网络下的通过学习和模仿自组织形成群落的现象,同时进行了仿真实验.分析了回报比率β和重连概率p与经纪人群落演化的关系,得出了在不同参数下群落规模分布的规律,以及模型系统方差变化的规律,为更好地研究社会经济系统中的涌现现象提供了一种新的方法.

Based on the analysis of MG(minority game) model and small-world model,this paper introduces a new kind of MG model in which the agents are placed on a small-world network and allowed them to imitate the most successful neighbor′s strategy.The information is not free for imitators.They have to pay their incoming to the imitated agents at the rate.The paper shows the result of simulation and analyzes the size distribution of the domain formed during the imitation of the model with different parameters.When β...
