WebMay 9, 2024 · Both of the algorithms, Boyer Moore and Boyer Moore Horspool, use some knowledge about the pattern string to skip fruitless comparisons. In order to be “smarter”, each algorithm does a preprocessing that analyses the input pattern. The complexity of the preprocessing usually depends on the size of the alphabet of the string.

This algorithm compares each characters of substring to find a word or the same characters into the string. When characters do not match, the search jumps to the next matching position in the pattern by the value indicated in the Bad Match Table.
