设施博弈的近似无钱机制设计综述

A Survey on Approximation Mechanism Design without Money for Facility Games

Yukun Cheng, Sanming Zhou

摘要:

在设施博弈中,一个或多个设施被放置在度量空间中,以服务于一组自私的代理,这些代理的地址是他们的私人信息。在一个经典的设施博弈中,每个智能体都希望尽可能地靠近一个设施,智能体的成本可以定义为她的位置和最近的设施之间的距离。在一个讨厌的设施博弈中,每个智能体都希望远离所有设施,她的效用是从她的位置到设施集的距离。每个代理人的目标是最小化她的成本或最大化她的效用。代理人可以说谎,如果这样做可以获得更多的利益。我们对不使用支付的社会选择机制感兴趣。游戏设计者的目标是一种防策略的机制,在这个意义上,任何代理人都不能通过误报她的地址而受益,或者,更好的是,群体防策略的机制,在这个意义上,任何代理人的联盟都不能通过撒谎而受益。同时,期望具有相对于所选择的目标函数近似最优的机制。几种模型,这种近似机制设计没有钱的设施游戏已被提出。在本文中,我们简要回顾了这些模型和相关结果的确定性和随机机制,同时,我们提出了一个一般的框架,近似机制设计没有钱的设施游戏。

英文摘要:

In a facility game one or more facilities are placed in a metric space to serve a set of selfish agents whose addresses are their private information. In a classical facility game, each agent wants to be as close to a facility as possible, and the cost of an agent can be defined as the distance between her location and the closest facility. In an obnoxious facility game, each agent wants to be far away from all facilities, and her utility is the distance from her location to the facility set. The objective of each agent is to minimize her cost or maximize her utility. An agent may lie if, by doing so, more benefit can be obtained. We are interested in social choice mechanisms that do not utilize payments. The game designer aims at a mechanism that is strategy-proof, in the sense that any agent cannot benefit by misreporting her address, or, even better, group strategy-proof, in the sense that any coalition of agents cannot all benefit by lying. Meanwhile, it is desirable to have the mechanism to be approximately optimal with respect to a chosen objective function. Several models for such approximation mechanism design without money for facility games have been proposed. In this paper we briefly review these models and related results for both deterministic and randomized mechanisms, and meanwhile we present a general framework for approximation mechanism design without money for facility games.
