.假设n个男孩和n个女孩随机排列。我们证明,在由这些排序定义的所有盖尔/沙普利稳定匹配的集合中,任何特定的女孩至少有(12 − 1)ln n个不同的丈夫,最多有(1 + 1)ln n个不同的丈夫,当n → ∞时,概率接近1,如果n是任何正的常数。证明强调的一般方法,似乎是有用的许多其他组合算法的分析。
. Suppose n boys and n girls rank each other at random. We show that any particular girl has at least ( 12 − ǫ ) ln n and at most (1 + ǫ ) ln n different husbands in the set of all Gale/Shapley stable matchings defined by these rankings, with probability approaching 1 as n → ∞ , if ǫ is any positive constant. The proof emphasizes general methods that appear to be useful for the analysis of many other combinatorial algorithms.
