CommonSubsequenceRun-LengthThe present article reveals that the problem of finding the longest common subsequence of two strings given in run-length encoded form can be solved in O(mn log log min(m, n, M/m, N/n, X)) time, where one input string is of length M with m runs, the ...
A subsequence of a string is anewstring generated from the original string with some characters(can be none) deleted without changing the relative order of the remaining characters. (eg, "ace" is a subsequence of "abcde"while"aec"is not). A common subsequence of two strings is a subsequenc...
A subsequence of a string is a new string generated from the original string with some characters (can be none) deleted without changing the relative order of the remaining characters. For example, "ace" is a subsequence of "abcde". A common subsequence of two strings is a subsequence that ...

Longest Common Subsequence 给出两个字符串,找到最长公共子序列(LCS),返回LCS的长度。 说明 最长公共子序列的定义: • 最长公共子序列问题是在一组序列(通常2个)中找到最长公共子序列(注意:不同于子串,LCS不需要是连续的子串)。该问题是典型的计算机科学问题,是文件差异比较程序的基础,在生物信息学中也有所应用...
Bounds on the Complexity of the Longest Common Subsequence Problem The problem of finding a longest common subsequence of two strings is discussed. This problem arises in data processing applications such as comparing two ... JD Ullman,AV Aho,DS Hirschberg - 《Journal of the Acm》 被引量: ...
One of the time bounds claimed for a recent algorithm computing the longest common subsequence of two strings is shown not to correct. While this fact considerably affects the performance of that algorithm, it also contributes to pose a few interesting questions.关键词: Analysis of algorithms longe...
