文本比较算法Ⅷ——再议Nakatsu算法

研究文本比较算法已经一段时间了。把思路重新理了理。　　在“文本比较算法Ⅳ——Nakatsu算法”中提到“对角线上的数字就是最长公共子序列的下标”。　　在“文本比较算法Ⅶ——线性空间求最长公共子序列的Nakatsu算法”中提到“每行最左边不为V的数字就是最长公共子序列的下标”。　　以上两个结论，...

文本比较算法Ⅳ——Nakatsu算法

　在“文本比较算法Ⅰ——LD算法”、“文本比较算法Ⅱ——Needleman/Wunsch算法”中介绍的LD算法和LCS算法都是基于动态规划的。它们的时间复杂度O(MN)、空间复杂度O(MN)（在基于计算匹配字符串情况下，是不可优化的。如果只是计算LD和LCS，空间占用可以优化到O(M)）。　　Na...
