异质性在协同进化空间博弈中作用的进一步分析

A Further Analysis of The Role of Heterogeneity in Coevolutionary Spatial Games

Marcos Cardinot, Josephine Griffith, Colm O'Riordan

摘要:

异质性被认为是对社会困境中合作之谜最常见的解释之一。大量的论文已经发表,讨论日益增加的异质性结构化人口的代理,它已被确定,异质性可能有利于合作行为,如果它支持代理本地协调他们的策略的影响。在本文中,假设一个异构加权网络的现有模型,我们的目标是进一步探索异质性和合作之间的关系(如果有的话),这种分析。我们采用了一个加权网络,该网络完全由玩囚徒困境或可选囚徒困境游戏的智能体填充,这些智能体具有共同进化规则,即,不仅策略而且链路权重也随着时间而演变。令人惊讶的是,结果表明,异质性的链接权重(国家)本身并不总是促进合作,而是合作实际上是有利于增加重叠的国家,而不是由异质性本身的数量。我们相信,这些结果可以指导进一步的研究,对异质性在社会困境中的作用进行更准确的分析。

英文摘要:

Heterogeneity has been studied as one of the most common explanations of the puzzle of cooperation in social dilemmas. A large number of papers have been published discussing the effects of increasing heterogeneity in structured populations of agents, where it has been established that heterogeneity may favour cooperative behaviour if it supports agents to locally coordinate their strategies. In this paper, assuming an existing model of a heterogeneous weighted network, we aim to further this analysis by exploring the relationship (if any) between heterogeneity and cooperation. We adopt a weighted network which is fully populated by agents playing both the Prisoner's Dilemma or the Optional Prisoner's Dilemma games with coevolutionary rules, i.e., not only the strategies but also the link weights evolve over time. Surprisingly, results show that the heterogeneity of link weights (states) on their own does not always promote cooperation; rather cooperation is actually favoured by the increase in the number of overlapping states and not by the heterogeneity itself. We believe that these results can guide further research towards a more accurate analysis of the role of heterogeneity in social dilemmas.
