不可分割家务的公平高效分配新算法

New Algorithms for the Fair and Efficient Allocation of Indivisible Chores

Jugal Garg, Aniket Murhekar, John Qin

AI总结:

本文提出新算法,证明在多种条件下(如三智能体、至多两种负效用函数等)存在同时满足EF1/EFX与分数帕累托最优的不可分割家务分配,并指出某些情况下EFX+fPO分配不存在。

摘要:

我们研究了在具有加性负效用函数的智能体之间公平且高效地分配不可分割家务的问题。我们考虑了广泛使用的基于嫉妒的公平性属性EF1和EFX,并结合了分数帕累托最优性(fPO)的效率属性。同时满足EF1/EFX和fPO的分配的存在性(及计算)是挑战性的开放问题,我们在两个问题上都取得了进展。我们证明了以下分配的存在性:当有三个智能体时,存在EF1+fPO分配;当至多有两个负效用函数时,存在EF1+fPO分配;对于具有双值负效用的三个智能体,存在EFX+fPO分配。这些结果是构造性的,基于强多项式时间算法。我们还研究了不存在性,并表明即使对于两个智能体,EFX+fPO分配也可能不存在。

英文摘要:

We study the problem of fairly and efficiently allocating indivisible chores among agents with additive disutility functions. We consider the widely-used envy-based fairness properties of EF1 and EFX, in conjunction with the efficiency property of fractional Pareto-optimality (fPO). Existence (and computation) of an allocation that is simultaneously EF1/EFX and fPO are challenging open problems, and we make progress on both of them. We show existence of an allocation that is - EF1+fPO, when there are three agents, - EF1+fPO, when there are at most two disutility functions, - EFX+fPO, for three agents with bivalued disutilities. These results are constructive, based on strongly polynomial-time algorithms. We also investigate non-existence and show that an allocation that is EFX+fPO need not exist, even for two agents.
