Description
Edit distances algorithms for fuzzy matching. Specifically, this library provides:
They have been fairly heavily optimized. Indeed, for situations where one of the strings is under 64 characters long we use a rather neat "bit vector" algorithm: see the authors paper and the associated errata for more information. The algorithms could be faster, but they aren't yet slow enough to force us into improving the situation.
