摘要:

我们调查的查询复杂性的公平分配不可分割的商品。对于两个代理任意单调的效用,我们设计了一个算法,计算分配满足envy-freeness一个好(EF 1),envy-freeness放松,使用对数查询。我们发现,对数查询复杂性界也适用于三个代理商与添加剂的效用,和一个polylogarithmetic界持有三个代理商与单调的效用。这些结果表明,即使在商品数量非常大的情况下,在实践中也有可能公平地分配商品。相比之下,我们证明了计算分配满足羡慕自由和另一个放松,羡慕自由的任何好(EFX),需要一个线性数量的查询,即使只有两个代理具有相同的附加效用。

英文摘要:

We investigate the query complexity of the fair allocation of indivisible goods. For two agents with arbitrary monotonic utilities, we design an algorithm that computes an allocation satisfying envy-freeness up to one good (EF1), a relaxation of envy-freeness, using a logarithmic number of queries. We show that the logarithmic query complexity bound also holds for three agents with additive utilities, and that a polylogarithmic bound holds for three agents with monotonic utilities. These results suggest that it is possible to fairly allocate goods in practice even when the number of goods is extremely large. By contrast, we prove that computing an allocation satisfying envy-freeness and another of its relaxations, envy-freeness up to any good (EFX), requires a linear number of queries even when there are only two agents with identical additive utilities.
