Commentz-Walter algorithm : ウィキペディア英語版 | Commentz-Walter algorithm
In computer science, the Commentz-Walter algorithm is a string searching algorithm invented by Beate Commentz-Walter. Like the Aho–Corasick string matching algorithm, it can search for multiple patterns at once. It combines ideas from Aho–Corasick with the fast matching of the Boyer–Moore string search algorithm. For a text of length ''n'' and maximum pattern length of ''m'', its worst-case running time is O(''mn''), though the average case is often much better. GNU grep implements a string matching algorithm very similar to Commentz-Walter.〔http://git.savannah.gnu.org/cgit/grep.git/tree/src/kwset.c〕 == References ==
