空间协同进化可选囚徒困境博弈中的循环优势
Cyclic Dominance in the Spatial Coevolutionary Optional Prisoner's Dilemma Game
摘要：
本文研究了在一个共同进化的空间模型中，博弈策略和代理之间的链接自适应地随着时间的推移而演变的循环优势的情况。选择性囚徒困境（Optional Prisoner's Dilemma，OPD）博弈。OPD是传统囚徒困境的扩展版本，玩家有第三个选择放弃玩游戏。我们采用了基于代理的模拟方法，并使用蒙特卡罗方法进行协同进化规则的OPD。此外，还研究了打破循环优势的必要条件。这项工作突出表明，循环优势是维持生物多样性的关键。此外，我们还讨论了空间协同进化模型在维持循环优势在不利条件下的重要性。
英文摘要：
This paper studies scenarios of cyclic dominance in a coevolutionary spatial model in which game strategies and links between agents adaptively evolve over time. The Optional Prisoner's Dilemma (OPD) game is employed. The OPD is an extended version of the traditional Prisoner's Dilemma where players have a third option to abstain from playing the game. We adopt an agent-based simulation approach and use Monte Carlo methods to perform the OPD with coevolutionary rules. The necessary conditions to break the scenarios of cyclic dominance are also investigated. This work highlights that cyclic dominance is essential in the sustenance of biodiversity. Moreover, we also discuss the importance of a spatial coevolutionary model in maintaining cyclic dominance in adverse conditions.
