Das Problem der stabilen Ehe ist eines der stabilen Übereinstimmungsprobleme, die 1962 von D. Gale und L. S. Shapley vorgeschlagen wurden. Ein Beispiel für ein stabiles Eheproblem sind N Männer und N Frauen sowie eine Wunschliste für jeden Einzelnen. Die Wunschliste ist eine Liste, in der alle unterschiedlichen Geschlechter in voller Reihenfolge nach den Vorlieben jedes Einzelnen angeordnet sind. Die Lösung für das Problem der stabilen Ehe ist die stabile Übereinstimmung. Im Gegensatz zum Beispiel des Problems der stabilen Ehe wird Matching, bei dem es kein Paar gibt (im Folgenden als blockierendes Paar bezeichnet), das Ihnen besser gefällt als die andere Partei, die Sie gerade bilden, als stabiles Matching bezeichnet. https://ja.wikipedia.org/wiki/%E5%AE%89%E5%AE%9A%E7%B5%90%E5%A9%9A%E5%95%8F%E9%A1%8C
