WebDec 18, 2016 · In Python it is not uncommon for algorithmically "slower" approaches which better exploit built-in methods (running in optimized compiled C) perform better than algorithmically "faster" algorithms which are implemented in interpreted code. That is one of those inefficiencies which can be hidden in a constant of proportionality. – John Coleman WebApr 26, 2016 · 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 length of the search string is N.
