动态网络社会中合作与协调的演化

Evolution of Cooperation and Coordination in a Dynamically Networked Society

Enea Pestelacci, Marco Tomassini, Leslie Luthi

摘要:

引发社会困境的冲突情境在社会中普遍存在,博弈论是研究冲突情境的主要方法之一。从观察社会中的个人通过熟人网络进行互动开始,我们使用两个原型游戏,囚徒困境和猎鹿游戏,对代理策略和社交网络本身的共同进化进行了建模。允许代理人解除关系,建立新的,我们发现,合作和协调可以通过社会网络的自组织,一个结果是不平凡的,特别是在囚徒困境的情况下实现。合作的演变和稳定性意味着凝聚剂利用特定的游戏策略,成为强大和稳定的集群连接更紧密,即使在更困难的情况下的囚徒困境。

英文摘要:

Situations of conflict giving rise to social dilemmas are widespread in society and game theory is one major way in which they can be investigated. Starting from the observation that individuals in society interact through networks of acquaintances, we model the co-evolution of the agents' strategies and of the social network itself using two prototypical games, the Prisoner's Dilemma and the Stag Hunt. Allowing agents to dismiss ties and establish new ones, we find that cooperation and coordination can be achieved through the self-organization of the social network, a result that is non-trivial, especially in the Prisoner's Dilemma case. The evolution and stability of cooperation implies the condensation of agents exploiting particular game strategies into strong and stable clusters which are more densely connected, even in the more difficult case of the Prisoner's Dilemma.
