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… WebApr 8, 2014 · Would the runtime for this algorithm be O(nm)? I'm comparing it to the worst-case runtime for the Horspool string-matching algorithm, which is also (nm). I guess my confusion stems from the fact that my algorithm appears initially as O(n) runtime as it simply iterates through the input n, using the indices as inputs to a slice notation equality ...
