基于记忆的网络雪堆博弈

Memory-Based Snowdrift Game on Networks

摘要:

我们提出了一个基于记忆的雪堆游戏(MBSG)发生在网络上。我们发现,当一个格子是底层结构,在一些关键值的支付参数的空间模式的过渡是可观察到的4和8邻居格子。局部稳定性分析可以解释过渡点和空间格局的类型。与以前报道的结果形成鲜明对比的是,合作促进了MBSG的空间结构。有趣的是,我们发现MBSG在无标度网络上的合作频率在支付参数的特定值处达到峰值。这一现象表明,适当地鼓励自私行为可以最佳地促进合作。详细讨论了个体的记忆效应,并在格子网络和无标度网络上观察到一些非单调现象。我们的工作可能会为网络上的进化博弈研究提供一些新的思路。

英文摘要:

We present a memory-based snowdrift game (MBSG) taking place on networks. We found that, when a lattice is taken to be the underlying structure, the transition of spatial patterns at some critical values of the payoff parameter is observable for both 4 and 8-neighbor lattices. The transition points as well as the styles of spatial patterns can be explained by local stability analysis. In sharp contrast to previously reported results, cooperation is promoted by the spatial structure in the MBSG. Interestingly, we found that the frequency of cooperation of the MBSG on a scale-free network peaks at a specific value of the payoff parameter. This phenomenon indicates that properly encouraging selfish behaviors can optimally enhance the cooperation. The memory effects of individuals are discussed in detail and some non-monotonous phenomena are observed on both lattices and scale-free networks. Our work may shed some new light on the study of evolutionary games over networks.
