Lcs time complexity
Web29 jul. 2024 · The problem of computing their longest common subsequence, or LCS, is a standard problem and can be done in O (nm) time using dynamic programming. Let’s define the function f. Given i and i, define f (i,j) as the length of the longest common subsequence of the strings A1,i and B1,j.

Web12 dec. 2006 · For the LCS problem of multiple sequences, the time complexity tends to grow very fast when the number of the sequences increases. For instance, using the Smith-Waterman algorithm to solve the LCS for multiple sequences, the time complexity is , where n is the number of sequences, and n i is the length of the i th sequence. WebTime complexity of the above naive recursive approach is O(2^n) in worst case and worst case happens when all characters of X and Y mismatch i.e., length of LCS is 0. In the …
