有限种群中策略演化的稳定性

Stability of Evolutionary Strategies in Finite Populations

  • 摘要: 针对有限种群上的博弈,人们给出不少定量的解析工作来刻画策略是如何在有限种群上达到稳定的。该文综述了有限种群中策略演化稳定性方面的一些代表性研究成果,着重介绍了无结构种群中的风险占优策略和占优策略,及结构种群中的结构占优策略等稳定性判据,特别是著名的1/3法则和σ法则。最后简要展望了该领域若干发展方向。

     

    Abstract: A lot of quantitative theoretical works have been proposed for evolutionary games aiming at evolutionary stable strategies in finite populations. In this paper, we review some latest representative researches, focusing on the risk-dominant strategy and advantageous strategy in well-mixed populations, and the structural dominant strategy in structured populations, including the famous 1/3 law and σ law. Finally, some future directions are pointed out.
