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.
