随机序列独裁的参数化算法

Parametrized Algorithms for Random Serial Dictatorship

Haris Aziz, Julián Mestre

摘要:

投票和分配是社会选择理论中两个最基本的背景。对于这两种设置,随机序列独裁(RSD)是一个众所周知的规则,满足匿名性,事后效率和防策略性。最近,它表明,计算结果的概率是#P-完全的投票和分配设置。在本文中,我们研究RSD从参数化的复杂性的角度来看。更具体地说,我们提出了有效的算法来计算RSD概率的条件下,代理类型,替代品,或对象的数量是有界的。

英文摘要:

Voting and assignment are two of the most fundamental settings in social choice theory. For both settings, random serial dictatorship (RSD) is a well-known rule that satisfies anonymity, ex post efficiency, and strategyproofness. Recently, it was shown that computing the resulting probabilities is #P-complete both in the voting and assignment setting. In this paper, we study RSD from a parametrized complexity perspective. More specifically, we present efficient algorithms to compute the RSD probabilities under the condition that the number of agent types, alternatives, or objects is bounded.
