带序偏好的设施选址博弈

Facility Location Games with Ordinal Preferences

Hau Chan, Minming Li, Chenhao Wang

摘要:

我们考虑了一个新的设置的设施位置的顺序偏好的游戏。在这样的环境中,我们有一套代理和一套设施。每个代理位于一条线上,并对设施有一个顺序偏好。我们的目标是设计的strategyproof机制,引出真实的信息(偏好和/或位置)从代理和定位的设施,以最大限度地减少最大和总成本的目标,以及最大限度地提高最小和总效用的目标。对于四个可能的目标,我们考虑2设施设置,其中只有偏好是私人的,或位置是私人的。对于每一个可能的目标和设置的组合,我们提供了上下限的近似比率的strategyproof机制,这是渐近紧到一个常数。最后,我们讨论了我们的结果的推广超出两个设施,当代理可以误报的位置和偏好。

英文摘要:

We consider a new setting of facility location games with ordinal preferences. In such a setting, we have a set of agents and a set of facilities. Each agent is located on a line and has an ordinal preference over the facilities. Our goal is to design strategyproof mechanisms that elicit truthful information (preferences and/or locations) from the agents and locate the facilities to minimize both maximum and total cost objectives as well as to maximize both minimum and total utility objectives. For the four possible objectives, we consider the 2-facility settings in which only preferences are private, or locations are private. For each possible combination of the objectives and settings, we provide lower and upper bounds on the approximation ratios of strategyproof mechanisms, which are asymptotically tight up to a constant. Finally, we discuss the generalization of our results beyond two facilities and when the agents can misreport both locations and preferences.
