我们提出了一个模型来解决社会系统中合作的演化如何依赖于空间运动和收益预期的问题。在该模型中，如果个体的实际收益小于其预期收益，个体将迁移到新地点或简单地改变其当前策略。结果表明，期望水平相对较低的不满意个体的迁移会导致合作者的聚集和合作的促进。此外，在适当的参数下，迁移会导致一些有趣的时空模式，这在以前的空间游戏研究中似乎没有报道过。此外，研究还发现具有恒定期望的群体比具有适应性期望的群体更倾向于合作行为。(C) 2011 Elsevier Ltd.版权所有。
We propose a model to address the problem how the evolution of cooperation in a social system depends on the spatial motion and the payoff expectation. In the model, if the actual payoff of an individual is smaller than its payoff expectation, the individual will either move to a new site or simply reverse its current strategy. It turns out that migration of dissatisfied individuals with relatively low expectation level leads to the aggregation of cooperators and promotion of cooperation. Moreover, under appropriate parameters migration leads to some interesting spatiotemporal patterns which seems not to have been reported in previously studied spatial games. Furthermore, it also found that a population with constant expectation can better favor cooperative behavior than a population with adaptive aspiration. (C) 2011 Elsevier Ltd. All rights reserved.
