空间结构对合作演化的影响

Effect of spatial structure on the evolution of cooperation

Carlos P. Roca, José A. Cuesta, Angel Sánchez

摘要:

空间结构对合作的演化具有重要影响,因此近年来得到了广泛的研究。以前的工作已经显示了一些功能的相关性,如同步性的更新,网络的聚类或更新规则的影响。然而,这是针对特定游戏,网络和更新规则的具体设置进行的,结果出现了一些矛盾,并且在2x2游戏空间的更广泛背景下缺少对这些主题的一般理解。为了解决这个问题,我们在不同的自由度的问题进行了系统和详尽的模拟。在某些情况下,我们将以前的知识推广到我们研究的更广泛的背景下,并解释明显的矛盾。然而,在其他情况下,我们的结论反驳了该领域似乎已确立的观点,例如空间结构对更新规则变化的影响的鲁棒性,或者提供了对该主题的新见解,例如选择强度与混合均衡博弈影响之间的不对称性之间的关系。

英文摘要:

Spatial structure is known to have an impact on the evolution of cooperation, and so it has been intensively studied during recent years. Previous work has shown the relevance of some features, such as the synchronicity of the updating, the clustering of the network or the influence of the update rule. This has been done, however, for concrete settings with particular games, networks and update rules, with the consequence that some contradictions have arisen and a general understanding of these topics is missing in the broader context of the space of 2x2 games. To address this issue, we have performed a systematic and exhaustive simulation in the different degrees of freedom of the problem. In some cases, we generalize previous knowledge to the broader context of our study and explain the apparent contradictions. In other cases, however, our conclusions refute what seems to be established opinions in the field, as for example the robustness of the effect of spatial structure against changes in the update rule, or offer new insights into the subject, e.g. the relation between the intensity of selection and the asymmetry between the effects on games with mixed equilibria.
