We examine opinion dynamics in multi-agent games. Each agent forms an opinion describing its preferences among multiple available strategies and exchanges its opinion with other agents. We explain how the model allows the agents to make rational and reciprocal decisions on strategy selection, both of which are key features observed in human decision making. Using bifurcation analysis, we establish how the agents switch between rational and reciprocal decision making, and we use the results to explain how cooperation emerges in the prisoner's dilemma. Using numerical examples, we illustrate the results of the bifurcation analysis and identify important aspects of rational and reciprocal decision making.

游戏中意见动态的理性与互惠

我们研究了多代理游戏中的意见动态。每个代理形成一个意见,描述其在多种可用策略中的偏好,并与其他代理交换意见。我们解释了该模型如何允许代理对策略选择做出理性和互惠的决策,这两者都是人类决策中观察到的关键特征。使用分叉分析,我们确定了代理如何在理性决策和互惠决策之间切换,并使用结果来解释合作如何在囚徒困境中出现。我们使用数值例子说明了分岔分析的结果,并确定了理性和互惠决策的重要方面。
