Abstract

In this paper, the fastest algorithm among Boyer Moore and Horspool Algorithms has been obtained. However, before the fastest algorithm can be determined, studies and analysis of both algorithms are required. At the fundamental stage, all the matching mechanisms as well as the shifting methodologies of both algorithms have been studied. After comprehending each algorithm, an in depth analysis with various premeditated cases are applied in order to test these algorithms. Factors are deliberated before the fastest string matching algorithm is obtained. Finally, a fair conclusion has been provided at the end of this paper.
