NeedlemanWunschSimilarity
NeedlemanWunschSimilarity[u, v]
gives a number representing the Needleman-Wunsch similarity between strings or vectors u and v.
Details and Options
- NeedlemanWunschSimilarity[u, v] finds an optimal global alignment between the elements of u and v, and returns the number of one-element matches.
- For strings, setting the option IgnoreCase->True makes NeedlemanWunschSimilarity treat lowercase and uppercase letters as equivalent.
- With the default setting SimilarityRules->Automatic, each match between two characters contributes
to the total similarity score, while each mismatch, insertion, or deletion contributes 
. - The option GapPenalty specifies an additional cost to be subtracted from the similarity score for any run of insertions or deletions.
