WebJun 2, 2011 · The insight behind Boyer-Moore is that if you start searching for a pattern in a string starting with the last character in the pattern, you can jump your search forward multiple characters when you hit a mismatch. Let's say our pattern p is the sequence of characters p1, p2, ..., pn and we are searching a string s, currently with p aligned so ... WebNov 15, 2024 · Bad character heuristics worst-case time complexity is O (mn) which may occur when both text T and pattern P have all characters the same, like in this case T=”ppppppppp” and P=”pppp”. In the best-case scenario, the bad character heuristic takes O (n/m) which may occur when all characters of pattern P and text T are different.
