平均收益对合作演化的自组织影响

The self-organizing impact of averaged payoffs on the evolution of cooperation

A. Szolnoki, M. Perc

摘要:

根据进化博弈论的基本原理,种群中更成功的策略应该传播。因此,在策略模仿过程中,参与者将其收益值与竞争策略的收益值进行比较。但这些信息并不总是准确的。为了避免歧义,学习者可能因此决定通过平均其邻居中对手的收益值来收集更可靠的统计数据,然后做出决定。这种对标准显微镜协议的简单改变显著提高了群体中的合作水平。此外,可以通过增加环境的作用和扩大评价圈的规模来加强积极影响。解释这种改进的机制是基于一个自组织的过程,揭示了在面对面的比较中仍然部分隐藏的叛逃者聚集的有害后果。值得注意的是,报告的现象并不限于晶格人口,但仍然有效的不规则的相互作用网络所描述的系统。

英文摘要:

According to the fundamental principle of evolutionary game theory, the more successful strategy in a population should spread. Hence, during a strategy imitation process a player compares its payoff value to the payoff value held by a competing strategy. But this information is not always accurate. To avoid ambiguity a learner may therefore decide to collect a more reliable statistics by averaging the payoff values of its opponents in the neighborhood, and makes a decision afterwards. This simple alteration of the standard microscopic protocol significantly improves the cooperation level in a population. Furthermore, the positive impact can be strengthened by increasing the role of the environment and the size of the evaluation circle. The mechanism that explains this improvement is based on a self-organizing process which reveals the detrimental consequence of defector aggregation that remains partly hidden during face-to-face comparisons. Notably, the reported phenomenon is not limited to lattice populations but remains valid also for systems described by irregular interaction networks.
