Fast String Searching Mechanism

The goal of this study is to introduce a novel exact string searching (i.e., matching) method based on the fuzzy transform, or F-transform (FTSS). The theoretical background of the F-transform, specifically the F-s-transform, s >= 0, for functions of one variable is reviewed, and a string searching algorithm based on this theory is presented. The algorithm is demonstrated with several examples. The results are compared with those of three existing string searching algorithms: Knuth-Morris-Pratt (KMP), Boyer-Moore (BM) and Rabin-Karp (RK).
