Smith–Waterman algorithm aligns two sequences by matches/mismatches (also known as substitutions), insertions, and deletions. Both insertions and deletions are the operations that introduce gaps, which are represented by dashes. The Smith–Waterman algorithm has several steps: 1. Determine the substitution matrix and the gap penalty scheme. A substitutio… fischerhof 1 hannover
