结构化无标度网络中的囚徒困境

Prisoner's dilemma in structured scale-free networks

Xing Li, Yonghui Wu, Zhihai Rong, Zhongzhi Zhang, Shuigeng Zhou

摘要:

传统观点认为,无标度网络更倾向于合作扩散。本文研究了结构化无标度网络上的合作行为。与无标度网络易于合作扩散的传统观点相反,在结构化无标度网络上进行囚徒困境(PD)博弈时,合作的演化受到抑制。首先,我们证明了结构化无标度网络的无标度特性和高聚类系数都不是抑制合作传播的原因。然后,我们提供了一个启发式的方法,认为缺乏年龄的相关性和相关的“大世界”的行为在结构化的无标度网络抑制了合作的传播。这一发现有助于进一步研究无标度网络中PD博弈的演化动力学。

英文摘要:

The conventional wisdom is that scale-free networks are prone to cooperation spreading. In this paper we investigate the cooperative behaviors on the structured scale-free network. On the contrary of the conventional wisdom that scale-free networks are prone to cooperation spreading, the evolution of cooperation is inhibited on the structured scale-free network while performing the prisoner's dilemma (PD) game. Firstly, we demonstrate that neither the scale-free property nor the high clustering coefficient is responsible for the inhibition of cooperation spreading on the structured scale-free network. Then we provide one heuristic method to argue that the lack of age correlations and its associated `large-world' behavior in the structured scale-free network inhibit the spread of cooperation. The findings may help enlighten further studies on evolutionary dynamics of the PD game in scale-free networks.
