AI总结:

本文研究了图上距离保持博弈的稳定性问题,探讨了三种稳定性概念,并分析了问题在拓扑结构、智能体数量和偏好结构等维度上的复杂性。

摘要:

我们引入了一种新的网络分配博弈,称为图距离保持博弈。在此问题中,给定一个称为拓扑的图,以及需要分配到其顶点上的若干智能体。此外,每个智能体都有一个理想(可能不同的)距离,使其与其他某些智能体保持一定距离。给定一个智能体的分配方案,每个智能体的代价是其子集中每个智能体与理想距离的差异之和。目标是确定是否存在稳定的智能体分配,即没有智能体希望从当前位置转移。具体来说,我们考虑了三种不同的稳定性概念:公平性、交换稳定性以及跳跃稳定性。我们从三个不同的维度对问题的(参数化)复杂性进行了全面研究:图的拓扑结构、智能体数量以及智能体偏好结构。

英文摘要:

We introduce a new class of network allocation games called graphical distance preservation games. Here, we are given a graph, called a topology, and a set of agents that need to be allocated to its vertices. Moreover, every agent has an ideal (and possibly different) distance in which to be from some of the other agents. Given an allocation of agents, each one of them suffers a cost that is the sum of the differences from the ideal distance for each agent in their subset. The goal is to decide whether there is a stable allocation of the agents, i.e., no agent would like to deviate from their location. Specifically, we consider three different stability notions: envy-freeness, swap stability, and jump stability. We perform a comprehensive study of the (parameterized) complexity of the problem in three different dimensions: the topology of the graph, the number of agents, and the structure of preferences of the agents.
