不可分割对象公平分配的AL方法的推广

A Generalization of the AL method for Fair Allocation of Indivisible Objects

Haris Aziz

摘要:

我们考虑的分配问题,其中代理表示顺序偏好$m$对象和对象分配给代理的基础上的偏好。在最近的一篇论文中,Brams,Kilgour和Klamler(2014)提出了AL方法来计算两个代理的无嫉妒分配。AL方法主要依赖于代理对对象有严格偏好的假设。我们推广的AL方法的情况下,代理人可能会表示无差异,并证明算法所满足的公理性质。作为推广的结果,我们也得到了一个$O(m)$加速以前的算法,以检查是否存在一个完整的无嫉妒分配或没有。最后,我们表明,除非P=NP,可以没有多项式时间的GAL扩展到任意数量的代理商的情况下。

英文摘要:

We consider the assignment problem in which agents express ordinal preferences over $m$ objects and the objects are allocated to the agents based on the preferences. In a recent paper, Brams, Kilgour, and Klamler (2014) presented the AL method to compute an envy-free assignment for two agents. The AL method crucially depends on the assumption that agents have strict preferences over objects. We generalize the AL method to the case where agents may express indifferences and prove the axiomatic properties satisfied by the algorithm. As a result of the generalization, we also get a $O(m)$ speedup on previous algorithms to check whether a complete envy-free assignment exists or not. Finally, we show that unless P=NP, there can be no polynomial-time extension of GAL to the case of arbitrary number of agents.
