计算社会选择中的偏好限制:综述

Preference Restrictions in Computational Social Choice: A Survey

Edith Elkind, Martin Lackner, Dominik Peters

AI总结:

该综述从计算社会选择视角梳理经典与现代受限偏好域的性质及应用,涵盖相关经济学与社会选择文献,重点关注偏好域识别与难计算投票规则的胜者确定算法。

摘要:

在受限偏好域(如单峰偏好、单交叉偏好和欧几里得偏好)上,社会选择问题会更易处理。许多不可能性定理不再成立,其结构使偏好推理更简便,计算问题也能更高效地求解。本综述从计算社会选择的视角,对众多经典与现代的受限偏好域进行全面梳理,探究其性质与应用,以计算问题为研究导向,同时也涵盖了经济学与社会选择领域文献的综合讨论。综述的重点关注方向包括:识别偏好是否属于特定偏好域的算法,以及在偏好不受限时计算难度较高的投票规则的胜者确定算法。

英文摘要:

Social choice becomes easier on restricted preference domains such as single-peaked, single-crossing, and Euclidean preferences. Many impossibility theorems disappear, the structure makes it easier to reason about preferences, and computational problems can be solved more efficiently. In this survey, we give a thorough overview of many classic and modern restricted preference domains and explore their properties and applications. We do this from the viewpoint of computational social choice, letting computational problems drive our interest, but we include a comprehensive discussion of the economics and social choice literatures as well. Particular focus areas of our survey include algorithms for recognizing whether preferences belong to a particular preference domain, and algorithms for winner determination of voting rules that are hard to compute if preferences are unrestricted.
