互动强度对合作演化的影响

Effect of interaction strength on the evolution of cooperation

Feng Wenfeng, Li Yang, Yan Junhao

摘要:

合作行为在自然界中普遍存在,这是进化生物学的一个难题,因为背叛者总是比合作者获得更多的利益,因此,合作者应该随着时间的推移而减少或消失。这种典型的“囚徒困境”现象近年来得到了广泛的研究。本文介绍了合作者与背叛者之间的相互作用强度(在人类社会中,可以理解为合作者的容忍度)我们发现,只有当最大相互作用强度在两个临界值之间时,合作者和背叛者才能共存,否则,1)如果大于上限值,合作者将消失,2)如果小于较低值,则会出现一个不稳定状态。

英文摘要:

Cooperative behaviors are ubiquitous in nature,which is a puzzle to evolutionary biology,because the defector always gains more benefit than the cooperator,thus,the cooperator should decrease and vanish over time.This typical "prisoners' dilemma" phenomenon has been widely researched in recent years.The interaction strength between cooperators and defectors is introduced in this paper(in human society,it can be understood as the tolerance of cooperators).We find that only when the maximum interaction strength is between two critical values,the cooperator and defector can coexist,otherwise, 1) if it is greater than the upper value,the cooperator will vanish, 2) if it is less than the lower value,a bistable state will appear.
