Fast Variants of the Backward-Oracle-Marching Algorithm

This study focuses on the faster exact single pattern string matching algorithms. In all solutions, two variants of BOM, EBOM and FBOM are very efficient. We improved them and presented two algorithms named Simplified-EBOM and Simplified-FBOM through removing the unnecessary branches and accomplishing the core calculation of the algorithm in a 1-dimensional array. The experimental results indicated that Simplified-EBOM is fast for short patterns and it is 12% faster than its basis algorithm on average.
