摘要:

我们通过分析复杂网络中的最后通牒博弈来解决自然和社会系统中合作(类利他)行为如何产生的问题。具体而言,三种类型的球员被认为是:(a)移情,其愿望水平和报价是平等的,(b)务实的,谁不区分不同的角色,并旨在获得相同的利益,(c)代理人的愿望水平和报价是独立的。利用两种策略更新规则分析了纯种群在不同拓扑结构上的渐近行为。自然选择依赖于复制子动力学,而社会惩罚则受到巴克-斯奈彭动力学的启发,在这种动力学中,参与者受到社会选择规则的影响,不仅惩罚不太适合的个体,而且惩罚他们的第一个邻居。我们讨论了出现在不同的设置和网络拓扑结构的公平性。

英文摘要:

We address the problem of how cooperative (altruistic-like) behavior arises in natural and social systems by analyzing an ultimatum game in complex networks. Specifically, three types of players are considered: (a) empathetic, whose aspiration level and offer are equal, (b) pragmatic, who do not distinguish between the different roles and aim to obtain the same benefit, and (c) agents whose aspiration level and offer are independent. We analyze the asymptotic behavior of pure populations on different topologies using two kinds of strategic update rules. Natural selection, which relies on replicator dynamics, and Social Penalty, inspired in the Bak-Sneppen dynamics, in which players are subjected to a social selection rule penalizing not only the less fitted individuals, but also their first neighbors. We discuss the emergence of fairness in the different settings and network topologies.
