最近的研究表明，成功驱动的迁移可以促进进化博弈中自私个体之间的合作。然而，这种迁移机制依赖于有关个体状态及其预测计算能力的非局部信息。我们通过提出一种仅需要通过游戏交互获得的本地信息的替代迁移策略来研究自适应迁移在空间博弈框架中合作行为中的作用。我们的结果表明，适应性移民可以通过两种方式有效促进合作。首先，存在与空位密度和迁移速度相关的最佳迁移程度，这导致最高水平的合作。其次，适应性移民可以在叛逃者主导的环境中引发合作的爆发。这些发现适用于涉及成对互动的常见进化博弈类型。
Recent work has revealed that success-driven migration can promote cooperation among selfish individuals in evolutionary games. This migration mechanism relies, however, on nonlocal information about the states of the individuals and their computational capabilities for prediction. We investigate the role of adaptive migration in cooperative behavior in the framework of spatial game by proposing an alternative migration strategy that requires only local information obtainable through game interactions. Our results demonstrate that adaptive migration can be effective in promoting cooperation in two ways. First, there exists an optimal degree of migration associated with the density of empty sites and migration speed, which leads to the highest level of cooperation. Second, adaptive migration can induce an outbreak of cooperation from an environment dominated by defectors. These findings hold for common types of evolutionary games that involve pairwise interactions.
