本文研究了在截断偏好列表下稳定匹配问题的鲁棒性和效率,提出两种算法并证明经典DA算法在预测情况下的有效性。

摘要:

在本文中,我们研究了在双侧匹配市场中寻找稳定匹配的基本问题。在经典变体中,假设市场双方提交所有对方代理的排名列表。然而,在大型匹配市场如国家居民匹配计划(NRMP)中,医院无法面试或相互排名每个居民。在本文中,我们研究了具有截断偏好列表的稳定匹配问题。特别是,我们假设基于历史数据集,每个医院都有一个预测的匹配排名,并且只在该预测周围的有限区间内对居民进行排名。我们使用算法-预测框架,并证明用于计算稳定匹配的经典延迟接受(DA)算法对这种截断具有鲁棒性。我们提出了两种算法,并在理论上和经验上评估了它们的性能。我们的结果表明,即使预测相对准确,也可以显著减少实例大小(偏好列表的长度)以及提出的提案数量。这些结果解释了DA算法的实践成功,并将市场设计与新兴的算法-预测理论联系起来。

英文摘要:

In this paper, we study the fundamental problem of finding a stable matching in two-sided matching markets. In the classic variant, it is assumed that both sides of the market submit a ranked list of all agents on the other side. However, in large matching markets such as the National Resident Matching Program (NRMP), it is infeasible for hospitals to interview or mutually rank each resident. In this paper, we study the stable matching problem with truncated preference lists. In particular, we assume that, based on historical datasets, each hospital has a predicted rank of its likely match and only ranks residents within a bounded interval around that prediction. We use the algorithms-with-predictions framework and show that the classic deferred-acceptance (DA) algorithm used to compute stable matchings is robust to such truncation. We present two algorithms and theoretically and empirically evaluate their performance. Our results show that even with reasonably accurate predictions, it is possible to significantly cut down on both instance size (the length of preference lists) as well as the number of proposals made. These results explain the practical success of the DA algorithm and connect market design to the emerging theory of algorithms with predictions.
