研究随机博弈变化规则对合作行为进化的影响,揭示不同博弈类型对合作进化的影响差异。

摘要:

持续变化的环境在合作行为进化中起着关键作用。先前研究表明,不同博弈之间的转换,作为行为与环境之间的反馈,能显著促进合作行为。然而,定量分析局限于同质群体,而自然中的群体往往更复杂且高度异质。本文提供了在随机博弈中支持合作进化的分析方法,适用于任意空间异质性和收益结构。我们强调,博弈变化的规则和频率对进化结果有出人意料的多样性影响,这取决于所面临的社交困境。虽然随机博弈在捐赠博弈中有利于合作进化,但公共物品博弈和雪 drift 博弈则并非如此。因此,我们的框架和模型结果为长期存在的谜团提供了更细致的见解。

英文摘要:

Continuously changing environments have a paramount role in the evolution of cooperative behavior. Previous works have shown that the transitions among different games, as the feedback between behaviors and environments, can promote cooperative behavior significantly. Quantitative analysis, however, is limited to homogeneous populations, while realistic populations in nature are often more complex and highly heterogeneous. We hereby provide an analytical treatment of when the evolution of cooperation can be supported in stochastic games, applying to arbitrary spatial heterogeneity and payoff structure. We highlight that the rule and frequency of game changes can have surprisingly diverse effects on evolutionary outcomes, depending on the governing social dilemmas. While stochastic games favor the evolution of cooperation in donation games, this is not the case for public goods games and snowdrift games. Hence, our framework and model results offer a more subtle insight into the long-standing enigma.
