The 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-processing of the pattern in conjunction with suffix match lengths record… WebBoyer–Moore (BM) algorithm [4] for a single pattern to solve the multiple pattern matching problem (suﬃx-based approach). Set Horspool [12,21] may be considered its more practical simpliﬁcation, exactly in the way that Boyer–Moore–Horspool (BMH) [17] is a simpliﬁcation of the original BM.
