连续对策中多态种群状态的演化稳定性
Evolutionary Stability of Polymorphic Population States in Continuous Games
摘要:
在具有连续策略空间的游戏中,如果复制动态的静止点是渐近稳定的,则该静止点必须是可支持的(van Veelen,M.,Spreij,P.,2009.游戏中的进化具有连续的动作空间。经济Theory 39(3),355-376).在这篇文章中,我们解决了一个相反的问题,即我们证明了一个支持的人口状态是渐近稳定的变分范数时,它是强不可侵犯的。
英文摘要:
In games with continuous strategy spaces, if a rest point of the replicator dynamics is asymptotically stable then the rest point must be finitely supported (van Veelen, M., Spreij, P., 2009. Evolution in games with a continuous action space. Econom. Theory 39 (3), 355-376). In this article, we address the converse question that is, we prove that a finitely supported population state is asymptotically stable with respect to the variational norm when it is strongly uninvadable.
