TechReport;DI-CCTC-09-10http://hdl.handle.net/10198/4428ware of the need for faster and flexible searching algorithms in fields such as web searching or bioinformatics, we propose DC - a high-performance algorithm for exact pattern matching. Emphasizing the analysis of pattern peculiarities in the pre-processing phase, the algorithm en- compasses a novel search logic based on the examination of multiple alignments within a larger window, selectively tested after a powerful heuristic called compatibility rule is verified. The new algorithm’s performance is, on average, above its best-rated competitors when testing different data types and using a complete suite of pattern extensions and compositions. The flexibility is remarkable and the efficiency is more relevant in quaternary or greater alphabets.
