Damerau-Levenshtein distance is a metric measuring the edit distance between
two strings. It provides the minimum number of operations required to transform
one string to another, via
* insertion
* deletion
* substitution
* transposition
Many algorithms prefer to ignore the transpositons aspect of this problem, as
it adds signgficant complexity.
