Pareto Optimal Allocation under Compact Uncertain Preferences

Abstract: The assignment problem is one of the most well-studied settings in multi-agent resource allocation. Aziz, de Haan, and Rastegari (2017) considered this problem with the additional feature that agents’ preferences involve uncertainty. In particular, they considered two uncertainty models neither of which is necessarily compact. In this paper, we focus on three uncertain preferences models whose size is polynomial in the number of agents and items. We consider several interesting computational questions with reg… Show more

“…By Birkhoff's theorem [22], any bistochastic matrix can be represented as a convex combination of at most quadratic number of permutation matrices. 4 Hence, a ranking preference profile can always be represented as a lottery preference profile. This representation is not necessarily unique; that is, a ranking preference profile may have several or possibly even exponentially many lottery preference profile representation.…”

“…The field of resource allocation problems has been widely studied in recent years. A central class of problems in this field is the class of assignment problems [2,13,1,3,43,7,6,32,28]. In the most general, abstract formulation of an assignment problem (to which we will simply refer as the general assignment problem), an instance consists of a set of n agents and a set of m items.…”

“…A verification variant of the general assignment problem includes, in addition, some allocation as part of the input, and the question becomes whether this allocation is "optimal". Different notions of optimality have been considered in the literature, but the one that has received the most attention is pareto optimality (see, e.g., [2,7,6]). Intuitively, an assignment p is called pareto optimal if there is no other assignment q that is at least good as p for all agents and also strictly better than p for at least one agent.…”
