研究了空间动力学规则中存在淬灭不均匀性的演化囚徒困境博弈。遵循两种纯策略（合作或背叛）之一的参与者分布在二维格子上。从随机选择的邻居的策略采用率是由支付差异和一个两值的前因子w控制的，该因子表征了策略从其学习的参与者。运动员减少的教学活动是随机分布的集中。在开始和固定进一步。数值和分析计算进行研究的合作者的浓度作为一个函数的w和。不同的噪声水平和连接结构。在这一动态的广泛参数范围内，合作显著增加。研究结果强调了不对称性的重要性，在战略采用过程中的主从角色的交换。
Evolutionary Prisoner's Dilemma games with quenched inhomogeneities in the spatial dynamical rules are considered. The players following one of the two pure strategies ( cooperation or defection) are distributed on a two-dimensional lattice. The rate of strategy adoption from randomly chosen neighbors is controlled by the payoff difference and a two-value pre-factor w characterizing the players whom the strategy learned from. The reduced teaching activity of players is distributed randomly with concentrations. at the beginning and fixed further on. Numerical and analytical calculations are performed to study the concentration of cooperators as a function of w and. for different noise levels and connectivity structures. Significant increase of cooperation is found within a wide range of parameters for this dynamics. The results highlight the importance of asymmetry characterizing the exchange of master-follower role during the strategy adoptions.
