We formulate a theory of agent-based models in which agents compete to be in a winning group. The agents may be part of a network or not, and the winning group may be a minority group or not. An important feature of the present formalism is its focus on the dynamical pattern of strategy rankings, and its careful treatment of the strategy ties which arise during the system's temporal evolution. We apply it to the minority game with connected populations. Expressions for the mean success rate among the agents and for the mean success rate for agents with k neighbors are derived. We also use the theory to estimate the value of connectivity p above which the binary-agent-resource system with high resource levels makes the transition into the high-connectivity state.
我们构建了一种基于主体的模型理论,其中主体竞争以加入获胜群体。主体可能是网络的一部分,也可能不是,获胜群体可能是少数群体,也可能不是。当前形式主义的一个重要特征是其对策略排名动态模式的关注,以及对系统时间演化过程中出现的策略平局的谨慎处理。我们将其应用于具有连通群体的少数者博弈。推导了主体间平均成功率以及具有k个邻居的主体的平均成功率的表达式。我们还运用该理论来估计连通性p的值,高于此值时,具有高资源水平的二元主体 - 资源系统会转变为高连通性状态。
