Definition: The number of bits which differ between two binary strings. More formally, the distance between two strings A and B is ∑ | Ai - Bi |.

brute force string search with mismatches.
See also Levenshtein distance, Manhattan distance.
Note: After Ralf Rabaetje <email@example.com> 4 February 2000.
The Hamming distance can be interpreted as the number of bits which need to be changed (corrupted) to turn one string into the other. Sometimes the number of characters is used instead of the number of bits. Hamming distance can be seen as Manhattan distance between bit vectors.
