有没有好的算法编程解决数独的正确答案

【有没有好的算法编程解决数独的正确答案】 介绍一个大多数回答里头没提过的算法,Crook\u0026#39;s Algorithm。作者提到了一个概念叫 Preemptive Set —— 一种 "reduces the number of combinations in a clever way" 的方法。
A preemptive set is composed of numbers from the set and is a set of size m, 2 ≤ m ≤9, whose numbers are potential occupants of m cells exclusively, where exclusively means that no other numbers in the set other than the members of the preemptive set are potential occupants of those m cells.谁看懂了告诉我。
