考虑玩家更替的复制者动态

Replicator dynamics with turnover of players

Jeppe Juul, Ardeshir Kianercy, Sebastian Bernhardsson, Simone Pigolotti

摘要:

我们研究的自适应动态游戏中,玩家放弃人口在一个给定的速度,并取代了天真的球员,其特征在于先验分布超过承认的战略。我们展示了这样的过程如何导致宏观上的一个变种的复制方程,与一个额外的长期占球员营业额。我们研究如何纳什均衡和系统的动态修改这个额外的长期,为原型的例子,如岩石-纸-游戏和不同类别的两个动作之间的两个不同的人口的游戏。最后,我们展示了如何球员营业额可以占非平凡的偏离纳什均衡观察到的数据从最低的独特出价拍卖。

英文摘要:

We study adaptive dynamics in games where players abandon the population at a given rate, and are replaced by naive players characterized by a prior distribution over the admitted strategies. We demonstrate how such process leads macroscopically to a variant of the replicator equation, with an additional term accounting for player turnover. We study how Nash equilibria and the dynamics of the system are modified by this additional term, for prototypical examples such as the rock-scissor-paper game and different classes of two-action games played between two distinct populations. We conclude by showing how player turnover can account for non-trivial departures from Nash equilibria observed in data from lowest unique bid auctions.
