Optimal string alignment

WebSep 15, 2024 · The Optimal String Alignment distance (method='osa') is like the Levenshtein distance but also allows transposition of adjacent characters. Here, each substring may be edited only once. (For example, a character cannot be transposed twice to move it forward in the string).
