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. The algorithm trades space for time in order to obtain an average-case complexity of O(n) on random text, although it has O(nm) in the worst case, where the lengt… WebDownload Table Timings and memory consumption for exact string matching with the Horspool algorithm and a pattern of size 64 from publication: Journaled String Tree - A scalable data structure ... arxiv dataset https://kibarlisaglik.com

WebApr 26, 2016 · It is a mix between Boyer-Moore and Horspool algorithms plus couple of neat tricks. And from the wiki page of Boyer–Moore–Horspool algorithm [2]: The algorithm trades space for time in order to obtain an average-case complexity of O(N) on random text, although it has O(MN) in the worst case, where the length of the pattern is M and the ... WebUsing it alone produces a very efficient algorithm in practice. Horspool proposed to use only the bad-character shift of the rightmost character of the window to compute the shifts in the Boyer-Moore algorithm. The preprocessing phase is in O(m+sigma) time and O(sigma) space complexity.
