摘要

延迟接受（DA）算法的运行可能包含一些肯定会被拒绝的建议。我们引入了加速延迟接受算法，它的运行方式与 DA 算法类似，但排除了肯定会被拒绝的提议。加速延迟接受算法能输出与 DA 算法相同的稳定匹配结果，但效率更高：它能在极少数回合内终止，所需的提议数量也极少，而且最终配对匹配的时间不会晚于 DA 算法。

Speeding up deferred acceptance

A run of the deferred acceptance (DA) algorithm may contain proposals that are sure to be rejected. We introduce the accelerated deferred acceptance algorithm that proceeds in a similar manner to DA but with sure-to-be rejected proposals ruled out. Accelerated deferred acceptance outputs the same stable matching as DA but does so more efficiently: it terminates in weakly fewer rounds, requires weakly fewer proposals, and final pairs match no later. Computational experiments show that these efficiency savings can be strict.
