摘要:

我们研究公平分配不可分割的商品的问题,并专注于经典的公平比例概念。众所周知,商品的不可分割性对实现公平构成了非常重要的障碍,一项非常活跃的研究旨在使用适当的近似公平概念来规避这些障碍。最近的工作已经确定,即使是近似版本的比例(PROPx)可能是不可能实现的,即使是小的情况下,而最知名的可实现的近似(PROP1)要弱得多。我们引入了比例的概念,最大最小项目(PROPm),并展示了如何达到分配满足这一概念的任何情况下,涉及多达五个代理商与添加剂的估值。PROPm在PROP1和PROPx之间提供了一个动机良好的中间地带,同时也捕获了一些经过充分研究的最大化份额(MMS)基准的元素:另一个吸引了大量关注的比例放松。

英文摘要:

We study the problem of fairly allocating indivisible goods and focus on the classic fairness notion of proportionality. The indivisibility of the goods is long known to pose highly non-trivial obstacles to achieving fairness, and a very vibrant line of research has aimed to circumvent them using appropriate notions of approximate fairness. Recent work has established that even approximate versions of proportionality (PROPx) may be impossible to achieve even for small instances, while the best known achievable approximations (PROP1) are much weaker. We introduce the notion of proportionality up to the maximin item (PROPm) and show how to reach an allocation satisfying this notion for any instance involving up to five agents with additive valuations. PROPm provides a well-motivated middle-ground between PROP1 and PROPx, while also capturing some elements of the well-studied maximin share (MMS) benchmark: another relaxation of proportionality that has attracted a lot of attention.
