修正谢林博弈

Modified Schelling Games

Panagiotis Kanellopoulos, Maria Kyropoulou, Alexandros A. Voudouris

摘要:

我们介绍了一类修改谢林游戏中,有不同类型的代理谁占据的节点的位置图;代理相同类型的朋友,不同类型的代理是敌人。每个智能体都是有策略的,并跳转到图中的空节点,旨在最大化她的效用,定义为她的邻居中的朋友与包括她自己在内的邻居大小的比率。这与谢林博弈的相关文献相反,谢林博弈通常假设代理人在计算其大小时被排除在她的邻域之外。我们的模型使效用函数能够捕获可能的情况下,代理人宁愿周围有很多朋友,而不是只有几个,这方面在以前的工作中被部分忽略。我们提供了一个彻底的分析,在这种修改谢林游戏中出现的均衡(在)效率,通过界定无政府状态无政府代价和价格稳定的一般图形和有趣的特殊情况。我们的大多数结果是紧密的,并利用平衡的结构以及复杂的建设。

英文摘要:

We introduce the class of modified Schelling games in which there are different types of agents who occupy the nodes of a location graph; agents of the same type are friends, and agents of different types are enemies. Every agent is strategic and jumps to empty nodes of the graph aiming to maximize her utility, defined as the ratio of her friends in her neighborhood over the neighborhood size including herself. This is in contrast to the related literature on Schelling games which typically assumes that an agent is excluded from her neighborhood whilst computing its size. Our model enables the utility function to capture likely cases where agents would rather be around a lot of friends instead of just a few, an aspect that was partially ignored in previous work. We provide a thorough analysis of the (in)efficiency of equilibria that arise in such modified Schelling games, by bounding the price of anarchy and price of stability for both general graphs and interesting special cases. Most of our results are tight and exploit the structure of equilibria as well as sophisticated constructions.
