合作者通过同步克服迁移困境

Cooperators overcome migration dilemma through synchronization

Shubhadeep Sadhukhan, Rohitashwa Chattopadhyay, Sagar Chakraborty

摘要:

同步、合作和混沌是自然界中普遍存在的现象。在一个由许多不同的参与囚徒困境博弈的个体群体组成的种群中,存在一个迁移困境:没有合作者会迁移到一个参与囚徒困境博弈的群体中,以免被背叛者利用;但除非迁移发生,否则整个种群的合作者比例没有机会增加。采用随机重新布线耦合映射格子的混沌复制子映射,复制选择进化博弈动力学建模,我们证明了合作者-同步进化-克服迁移困境扩散到整个人口时,利他主义是温和的激励,使少数的德梅斯发挥领导者的游戏。

英文摘要:

Synchronization, cooperation, and chaos are ubiquitous phenomena in nature. In a population composed of many distinct groups of individuals playing the prisoner's dilemma game, there exists a migration dilemma: No cooperator would migrate to a group playing the prisoner's dilemma game lest it should be exploited by a defector; but unless the migration takes place, there is no chance of the entire population's cooperator-fraction to increase. Employing a randomly rewired coupled map lattice of chaotic replicator maps, modelling replication-selection evolutionary game dynamics, we demonstrate that the cooperators -- evolving in synchrony -- overcome the migration dilemma to proliferate across the population when altruism is mildly incentivized making few of the demes play the leader game.
