复杂网络上囚徒困境博弈中繁殖率的多样性支持合作

Diversity of reproduction rate supports cooperation in the prisoner's dilemma game on complex networks

A. Szolnoki, M. Perc, G. Szabo

摘要:

在人类社会中,个体的个人特征会影响个体策略采纳的概率。现在,我们研究如何人为施加限制的繁殖能力,推翻了一个人的健身,影响了进化过程。为了这个目的,我们采用进化囚徒困境游戏在不同的复杂图。繁殖限制可以有一个促进作用的合作,在不考虑互动网络的特殊性设置的演变。事实上,适当比例的生育能力较低的个体可能会导致合作者的完全优势,否则背叛将普遍存在。通过研究具有完全繁殖能力的个体组内的合作水平,我们发现,最近的促进合作的机制在概念上类似于以前报道的无标度网络。我们的研究结果表明,在繁殖能力的多样性,与固有的不同态度的个人,可以强制自私的竞争者之间的合作行为的出现。

英文摘要:

In human societies the probability of strategy adoption from a given person may be affected by the personal features. Now we investigate how an artificially imposed restricted ability to reproduce, overruling ones fitness, affects an evolutionary process. For this purpose we employ the evolutionary prisoner's dilemma game on different complex graphs. Reproduction restrictions can have a facilitative effect on the evolution of cooperation that sets in irrespective of particularities of the interaction network. Indeed, an appropriate fraction of less fertile individuals may lead to full supremacy of cooperators where otherwise defection would be widespread. By studying cooperation levels within the group of individuals having full reproduction capabilities, we reveal that the recent mechanism for the promotion of cooperation is conceptually similar to the one reported previously for scale-free networks. Our results suggest that the diversity in the reproduction capability, related to inherently different attitudes of individuals, can enforce the emergence of cooperative behavior among selfish competitors.
