摘要

动态环境在进化游戏系统中塑造了多种动态。本文将资源的空间异质性引入囚徒困境博弈模型,探讨具有环境反馈的协同进化博弈动力学。资源的可得性显著影响周围个体的生存竞争力。个人的策略和他们可以使用的资源之间的反馈导致了被称为“公地的振荡悲剧”的振荡动态。研究结果表明,在具有环境异质性的系统中,当个体策略对资源更新速率的影响很大时,个体可以达到一种平衡状态,从而避免振荡悲剧的发生。与在混合良好的结构中得到的数值结果相比,在利用方格的模拟中出现了自组织的聚类模式,进一步增强了系统的稳定性。我们详细讨论了关键现象,证明上述过渡在各种系统参数中都是鲁棒的,包括合作者在恢复环境中的强度、合作者的初始分布、系统大小和结构以及噪声。

Coevolutionary game dynamics with localized environmental resource feedback.

Dynamic environments shape diverse dynamics in evolutionary game systems. We introduce spatial heterogeneity of resources into the prisoner's dilemma game model to explore coevolutionary game dynamics with environmental feedback. The availability of resources significantly affects the survival competitiveness of surrounding individuals. Feedback between individuals' strategies and the resources they can use leads to the oscillating dynamic known as the "oscillatory tragedy of the commons." Our findings indicate that when the influence of individuals' strategies on the update rate of resources is significantly high in systems characterized by environmental heterogeneity, they can attain an equilibrium state that avoids the oscillatory tragedy. In contrast to the numerical results obtained in well-mixed structures, self-organized clustered patterns emerge in simulations utilizing square lattices, further enhancing the stability of the system. We discuss critical phenomena in detail, demonstrating that the aforementioned transition is robust across various system parameters, including the strength of cooperators in restoring the environment, initial distributions of cooperators, system size and structures, and noise.
