WebWe first tackle the problem of global alignment [1] . Global here means aligning the entire sequences. This contrasts with a “local” alignment, which computes the best aligned segment for a pair of sequences. That is solved using another dynamic programming algorithm referred to as Smith-Waterman, which we don’t address. 6.17.1.

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 …

WebBefore alignment with a pairwise dynamic programming algorithm, groups of aligned sequences are converted into profiles. A profile represents the character frequencies for each column in an alignment. In the final stage, for aligning groups of sequences, trace back information from full pairwise alignment is required.[ 17 ] ...
