Various implementations exist in different programming languages. In C++ it is part of the Standard Library since C++17, also Boost provides the generic Boyer–Moore search implementation under the Algorithm library. In Go (programming language) there is an implementation in search.go. D (programming language) uses a BoyerMooreFinder for predicate based matching within ranges as a part of the Phobos Runtime Library.

The algorithm in it basic sense finds a majority element, if it exists. Majority element is an element that occurs repeatedly for more than half of the input elements. However, if there is no majority, the algorithm will not detect that fact, and will still output one of the elements.

WebJun 2, 2011 · The insight behind Boyer-Moore is that if you start searching for a pattern in a string starting with the last character in the pattern, you can jump your search forward multiple characters when you hit a mismatch. Let's say our pattern p is the sequence of characters p1, p2, ..., pn and we are searching a string s, currently with p aligned so ... Web0.2 The Boyer-Moore Algorithm As in the naive algorithm, the Boyer-Moore algorithm successively aligns P with T and then checks whether P matches the opposing characters of T. Further, after the check is complete, P is shifted right relative to T just as in the naive algorithm. However, the Boyer-Moore algorithm contains three
