囚徒困境博弈中的多样性与批判行为

Diversity and critical behavior in prisoner's dilemma game

C. -K. Yun, N. Masuda, B. Kahng

摘要:

囚徒困境(PD)博弈是一个简单的模型,用于理解由自私个体组成的复杂系统中的合作模式。在这里,我们研究的PD游戏问题的无标度网络包含分层组织的模块和可控的捷径连接分离的枢纽。我们发现,合作者集群在参数空间(p,b)中表现出一个渗流过渡,其中p是捷径的占用概率,b是PD博弈中的诱惑收益。团簇尺寸分布在转变点处遵循幂律。这种临界行为是PD博弈中的随机过程和复杂网络的异质结构共同作用的结果,说明了现实世界系统中社会关系的多样性和合作者社区的自组织性。

英文摘要:

The prisoner's dilemma (PD) game is a simple model for understanding cooperative patterns in complex systems consisting of selfish individuals. Here, we study a PD game problem in scale-free networks containing hierarchically organized modules and controllable shortcuts connecting separated hubs. We find that cooperator clusters exhibit a percolation transition in the parameter space (p,b), where p is the occupation probability of shortcuts and b is the temptation payoff in the PD game. The cluster size distribution follows a power law at the transition point. Such a critical behavior, resulting from the combined effect of stochastic processes in the PD game and the heterogeneous structure of complex networks, illustrates the diversity of social relationships and the self-organization of cooperator communities in real-world systems.
