群体资源分配中的几乎无嫉妒性

Almost Envy-Freeness in Group Resource Allocation

Maria Kyropoulou, Warut Suksompong, Alexandros A. Voudouris

摘要:

我们研究的问题,公平分配不可分割的商品群体之间的代理商使用最近推出的放松嫉妒自由。我们考虑在不同的代理人估值假设下公平分配的存在。特别是,我们的研究结果涵盖的情况下,任意单调的,响应,和添加剂的估值,而对于二元估值的情况下,我们充分表征的基数的两组代理人的公平分配,可以保证相对于两个羡慕自由度一个好的(EF1)和羡慕自由度的任何好的(EFX)。此外,我们引入了一个新的模型,其中的代理人不被划分成组提前,而是分区可以选择与货物的分配。在这个模型中,我们表明,代理商与任意单调的估值,总是有一个分区的代理商成两组的任何给定的大小随着EF1分配的货物。我们还提供了一个扩展的结果,任何数量的群体。

英文摘要:

We study the problem of fairly allocating indivisible goods between groups of agents using the recently introduced relaxations of envy-freeness. We consider the existence of fair allocations under different assumptions on the valuations of the agents. In particular, our results cover cases of arbitrary monotonic, responsive, and additive valuations, while for the case of binary valuations we fully characterize the cardinalities of two groups of agents for which a fair allocation can be guaranteed with respect to both envy-freeness up to one good (EF1) and envy-freeness up to any good (EFX). Moreover, we introduce a new model where the agents are not partitioned into groups in advance, but instead the partition can be chosen in conjunction with the allocation of the goods. In this model, we show that for agents with arbitrary monotonic valuations, there is always a partition of the agents into two groups of any given sizes along with an EF1 allocation of the goods. We also provide an extension of this result to any number of groups.
