We study the evolution of cooperation in the prisoner's dilemma game on time-invariant heterogeneous payoff landscapes on regular and heterogeneous networks. Correlations in the landscape structure and their implications for the evolution of cooperation are investigated. On regular networks we find that negatively and neutrally correlated payoff landscapes strongly enhance cooperation, while positively correlated landscapes may suppress the evolution of cooperation. On heterogeneous networks, cooperation is facilitated if payoff stochasticity is positively correlated with network heterogeneity and may be suppressed otherwise.
我们研究了在时不变异的收益景观上的囚徒困境博弈中的合作演变,这些收益景观在规则网络和异质网络上。我们研究了景观结构中的相关性及其对合作进化的影响。在规则网络上,我们发现负相关和中性相关的收益景观强烈促进了合作,而正相关的收益景观可能会抑制合作的进化。在异质网络上,如果收益随机性与网络异质性正相关,合作会得到促进,否则合作可能会受到抑制。
