WebThe Boyer–Moore–Horspool algorithm is a simplification of the Boyer–Moore algorithm using only the bad character rule. The Apostolico–Giancarlo algorithm speeds up the process of checking whether a match has occurred at the given alignment by skipping explicit character comparisons. This uses information gleaned during the pre ... WebThere are many algorithms that start from the end. The simplest are the Horspool-type algorithms. The Horspool algorithm checks rst the text character aligned with the last pattern character. If it doesn't match, move (shift) the pattern forward until there is a match.

In computer science, the Boyer–Moore–Horspool algorithm or Horspool's algorithm is an algorithm for finding substrings in strings. It was published by Nigel Horspool in 1980 as SBM. It is a simplification of the Boyer–Moore string-search algorithm which is related to the Knuth–Morris–Pratt algorithm.
