Dynamic programming pairwise alignment
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 ] ... WebDynamic programming (DP) is a problem solving method for a class of problems that can be solved by dividing them down into simpler sub-problems. It finds the alignment by …
