随机复制动力学中的亚稳定性

Metastability in Stochastic Replicator Dynamics

Konstantin Avrachenkov, Vivek S. Borkar

摘要:

我们考虑一种新的模型的随机复制动力学的潜在的游戏,转换成一个朗之万方程的一个领域后,变量变换。这与先前研究的模型不同。特别是,由于解的非唯一性,它是不适定的,但服从自然选择原理,选择一个唯一的解。该模型使我们能够作出具体的陈述,如小噪声渐近平均退出时间从他们的吸引区域,准静态措施的亚稳态。我们说明了一般的结果,专门复制动力学图,并证明了数值实验支持理论预测。

英文摘要:

We consider a novel model of stochastic replicator dynamics for potential games that converts to a Langevin equation on a sphere after a change of variables. This is distinct from the models studied earlier. In particular, it is ill-posed due to non-uniqueness of solutions, but is amenable to a natural selection principle that picks a unique solution. The model allows us to make specific statements regarding metastable states such as small noise asymptotics for mean exit times from their domain of attraction, and quasi-stationary measures. We illustrate the general results by specializing them to replicator dynamics on graphs and demonstrate that the numerical experiments support theoretical predictions.
