异质噪声增强空间互易性
Heterogeneous noise enhances spatial reciprocity
摘要：
最近的研究表明，异质性是空间种群合作进化的关键。然而，异质噪声的影响仍然缺乏。受这个有趣问题的启发，在这项工作中，我们试图将异质噪声纳入效用评估，其中只有一部分人口拥有噪声，其范围也可以调整。我们发现，增加异质噪声单调促进合作，甚至翻译的充分叛逃阶段（同质版本）到完整的合作阶段。此外，该机制的促进作用可以归因于具有异质噪声的合作者的主导作用。这类合作者可以吸引更多的智能体渗透到健壮的合作者集群中，这是传统的空间互惠理论所不能比拟的。我们希望我们的工作能对社会上对合作行为的理解有所帮助。
英文摘要：
Recent research has identified the heterogeneity as crucial for the evolution of cooperation in spatial population. However, the influence of heterogeneous noise is still lack. Inspired by this interesting question, in this work, we try to incorporate heterogeneous noise into the evaluation of utility, where only a proportion of population possesses noise, whose range can also be tuned. We find that increasing heterogeneous noise monotonously promotes cooperation and even translates the full defection phase (of the homogeneous version) into the complete cooperation phase. Moreover, the promotion effect of this mechanism can be attributed to the leading role of cooperators who have the heterogeneous noise. These type of cooperators can attract more agents penetrating into the robust cooperator clusters, which is beyond the text of traditional spatial reciprocity. We hope that our work may shed light on the understanding of the cooperative behavior in the society.
