brute force string search with mismatches


Definition: Beginning with the (leftmost) position in a string and trying each position in turn, find the number of characters for which the pattern and the substring beginning at that position don't match (the Hamming distance). Return the first position with k or fewer mismatches.

Generalization (I am a kind of ...)
string matching with mismatches, brute force string search.
