分布式设施选址的近似机制设计

Approximate mechanism design for distributed facility location

Aris Filos-Ratsikas, Alexandros A. Voudouris

摘要:

我们考虑一个单一的设施选址问题,代理商被定位在真正的线,并划分成多个不相交的地区。目标是选择一个位置(公共设施将被建造的位置),以便最小化代理与该位置的总距离。该过程是分布式的:每个地区的代理的位置首先被聚合为该地区的代表位置,然后选择一个地区代表作为设施位置。这种对代理人位置的间接访问不可避免地导致低效率,这是扭曲概念所反映的。我们研究的离散版本的问题,其中的替代位置的集合是有限的,以及连续的,其中的每一个点的线是一个替代品,并绘制一个几乎完整的图片的失真景观的一般和strategypproof分布式机制。

英文摘要:

We consider a single-facility location problem, where agents are positioned on the real line and are partitioned into multiple disjoint districts. The goal is to choose a location (where a public facility is to be built) so as to minimize the total distance of the agents from it. This process is distributed: the positions of the agents in each district are first aggregated into a representative location for the district, and then one of the district representatives is chosen as the facility location. This indirect access to the positions of the agents inevitably leads to inefficiency, which is captured by the notion of distortion. We study the discrete version of the problem, where the set of alternative locations is finite, as well as the continuous one, where every point of the line is an alternative, and paint an almost complete picture of the distortion landscape of both general and strategyproof distributed mechanisms.
