Fast gap-affine pairwise alignment using the wavefront …

WebDynamic programming works by storing the result of subproblems so that when their solutions are required, they are at hand and we do not need to recalculate them. This technique of storing the value of subproblems is called memoization. By saving the values in the array, we save time for computations of sub-problems we have already come across. WebThe wavefront alignment (WFA) algorithm is an exact gap-affine algorithm that takes advantage of homologous regions between the sequences to accelerate the alignment …
