稳定婚姻问题算法，给定n男n女，以及每个人对异性对象的喜好程度（按1至n排列）。安排男女结婚，使得不出现以下不稳定情形：

在n男n女中的存在两对夫妇(M, W)和(m, w)，M男对w女喜好度大于现任妻子W女，并且w女对M男喜好度也大于现任丈夫m男。(In mathematics, economics, and computer science, the stable marriage problem (also stable matching problem or SMP) is the problem of finding a stable matching between two equally sized sets of elements given an ordering of preferences for each element. A matching is a mapping from the elements of one set to the elements of the other set. A matching is not stable if:

There is an element A of the first matched set which prefers some given element B of the second matched set over the element to which A is already matched, and
B also prefers A over the element to which B is already matched.
In other words, a matching is stable when there does not exist any match (A, B) by which both A and B would be individually better off than they are with the element to which they are currently matched.)
