Dynamic programmingSubstring inclusion constraintsTime complexityIn this paper, we consider a generalized longest common subsequence problem, in which a constraining sequence of length $s$ must be included as a substring and the other constraining sequence of length $t$ must be excluded as a ...
the length of the Longest Common Subsequence (LCS) using only 2*min(m, n) space plus O(1) additional space, you can use a technique called space optimization in the DP approach. Here's a Go implementation that demonstrates how to achieve this by only filling in necessary cells in the ...

In this case, using memory of previous individual bits (i.e. features) in the input strings is not enough to accurately predict the state labelled P. To avoid possibly confusing the middle position of the third sequence with the middle position of the other sequences, two bits must be ...
To motivate dynamic time warping, let's look at a classic dynamic programming problem: find the longest common subsequence (LCS) of two strings (Wikipedia). A subsequence is not required to maintain consecutive positions in the original strings, but they must retain their order. Examples:lcs('...
Dynamic programmingSimilarityConstraining sequencesTime complexityIn this paper, we consider a generalized longest common subsequence problem with multiple substring inclusive constraints. For the two input sequences $X$ and $Y$ of lengths $n$ and $m$, and a set of $d$ constraints $P=\\\{P_...
pylcsis a super fast c++ library which adopts dynamic programming(DP) algorithm to solve two classic LCS problems as below . The longest common subsequenceproblem is the problem of finding the longest subsequence common to all sequences in a set of sequences (often just two sequences). ...
