The program implements Needleman-Wunsch algorithm to produce a global alignment of two nucleotide sequences. The approach is described in "A general method applicable to the search for similarities in the amino acid sequence of two proteins", J Mol Biol. 48(3):443-53. The Needleman-Wunsch algorithm uses dynamic programming, and is guaranteed to find the alignment with the maximum score with respect to the scoring system being used (which includes the substitution matrix and the gap-scoring scheme.
