问题分析
数独解法基本靠暴力求解,在所有没有确定的位置对所有可能的解进行尝试,直接暴力解运行时间是153ms。所以在此之前先确定一下唯一解的位置,唯一解有两种类型。
该位置在所在行、列、宫上都满足的情况下的候选集只有一个;
该位置在所在行(列、宫)的所有未确定位置的候选集该值只出现一次。...

分析:
dlx是从数据结构角度优化01矩阵精确覆盖和重复覆盖的数据结构,它用十字链表只存贮矩阵中的非0元,而01矩阵精确覆盖dfs过程中矩阵会越来越稀疏而且每次恢复现场会浪费大量时间,dlx恰好能解决这两个问题。本题关键是将数独问题转化为01矩阵精确覆盖。数独转化为精确覆盖问题的方法还是参照Knuth的论文,如果读取到一个格子是空的,那么加9行,分别表示这个格子填1到9这9个数字,如果读取到的格...
