预算约束下的家务公平分配

Fair Division of Chores with Budget Constraints

Edith Elkind, Ayumi Igarashi, Nicholas Teh

AI总结:

该研究针对预算约束下的不可分割家务公平分配问题,提出预算约束分配模型,证明了EFX分配的存在性,给出不同场景下EF2、EF1分配的计算复杂度结论,并为可分割家务设计了高效的EF分配算法。

摘要:

我们研究预算约束下不可分割家务向智能体的公平分配问题,其中每项家务都有客观的规模和负效用。该模型刻画了一组家务需在时间有限的智能体间分配、且每项家务都有特定完成时长的场景。我们提出了一种用于分配不可分割家务的预算约束模型,并系统探究了该场景下物品与家务的差异。我们证明了EFX(无嫉妒至多任意一件物品)分配的存在性。随后我们表明,EF2(无嫉妒至多任意两件物品)分配通常可在多项式时间内计算;针对许多受限场景,我们将该结果强化为EF1(无嫉妒至多任意一件物品)。对于可分割家务,我们开发了一种计算EF(无嫉妒)分配的高效算法。

英文摘要:

We study fair allocation of indivisible chores to agents under budget constraints, where each chore has an objective size and disutility. This model captures scenarios where a set of chores need to be divided among agents with limited time, and each chore has a specific time needed for completion. We propose a budget-constrained model for allocating indivisible chores, and systematically explore the differences between goods and chores in this setting. We establish the existence of an EFX allocation. We then show that EF2 allocations are polynomial-time computable in general; for many restricted settings, we strengthen this result to EF1. For divisible chores, we develop an efficient algorithm for computing an EF allocation.
