Perc和Wang证明，在成对策略更新的条件下，渴望成为最适合的人，可以增强结构化群体在玩2×2囚徒困境游戏时的网络互惠性（Z。Wang，M. Perc，Aspiring to the fitter and promoted of collaboration in the Prisoner's Dilemma game，Physical Review E 82（2010）021115; M. Perc，Z. Wang，Heterogeneous aspiration promotes collaboration in the Prisoner's Dilemma game，PLOS one 5（12）（2010）e15117）.通过数值模拟，本文表明，网络互惠性更大，如果施加异构的愿望。我们还提出了为什么异质的愿望促进网络互惠。它在代理之间分配策略更新速度，以加强最初分配的合作者的集群免受入侵的方式。这一发现促使我们进一步增强异构网络拓扑结构的常见异构渴望情况。我们发现，程度和愿望水平之间的负相关性，并扩展异质结构的代理之间的合作。
Perc & Wang demonstrated that aspiring to be the fittest under conditions of pairwise strategy updating enhances network reciprocity in structured populations playing 2×2 Prisoner’s Dilemma games (Z. Wang, M. Perc, Aspiring to the fittest and promoted of cooperation in the Prisoner’s Dilemma game, Physical Review E 82 (2010) 021115; M. Perc, Z. Wang, Heterogeneous aspiration promotes cooperation in the Prisoner’s Dilemma game, PLOS one 5 (12) (2010) e15117). Through numerical simulations, this paper shows that network reciprocity is even greater if heterogeneous aspirations are imposed. We also suggest why heterogeneous aspiration fosters network reciprocity. It distributes strategy updating speed among agents in a manner that fortifies the initially allocated cooperators’ clusters against invasion. This finding prompted us to further enhance the usual heterogeneous aspiration cases for heterogeneous network topologies. We find that a negative correlation between degree and aspiration level does extend cooperation among heterogeneously structured agents.
