Whereas, the recursion algorithm has the complexity of 2max(m, n). Longest Common Subsequence Algorithm X and Y be two given sequences Initialize a table LCS of dimension X.length * Y.length X.label = X Y.label = Y LCS[0][] = 0 LCS[][0] = 0 Start from LCS[1][1] Compare ...
LCS for input Sequences “AGGTAB” and “GXTXAYB” is “GTAB” of length 4. 该问题最普通的解法是对两个给定序列分别生成所有子序列,然后找到最长的匹配的子序列。这样的解法是指数复杂度的,显然不是我们需要的。我们来看该问题是如何拥有动态规划问题的重要性质的。 1 Optimal Substructure: 假设输入...

Space saving techniques in computations of a longest common subsequence (LCS) of two strings are crucial in many applications, notably, in molecular sequence comparisons. For about ten years, however, the only linear-space LCS algorithm known required time quadratic in the length of the input, ...
Longest common subsequence 最长公共子序列(Longest common subsequence,LCS),不要跟最长公共子串(Longest common substring)搞混淆了。在很多情况下,我们想知道两个串有多相似,例如:两个短句,又或者两个DNA序列(DNA Sequence),也有一个富有代表性的工具diff。
