Dynamic programming pairwise alignment

Webalignment scores will derive the optimal multiple se-quence alignments. However, optimizing the multiple alignment score is a NP-complete problem [10] and even dynamic programming needs a time and space complexity O(LN) for N sequences with length L. Currently many ongoing multiple sequence alignment practices involve tens to hundreds … Webform as those for the dynamic programming of pairwise alignment (4.1). We will derive the exact form of the correspondence. First, we have to transform into log-odds ratios with respect to the random model. We already have a full probabilistic model for the alignment. We should also have one for our random model, with a proper termination ...
