1. What is the 'Levenshtein'?

Levenshtein is the Russian scientist by whom the edit distance calculation was invented. Mathematically it is a metric on the space of strings that defines this distance as minimal number of edit operations necessary to transform one of these two strings into the other. Edit operations can either be insertions, deletions or substitutions of characters. This operation obviously is symmetric and fulfills the triangle inequation.
