WebAug 27, 2024 · Finding a common superstring from many of the reads is a common task in bioinformatics. In this video, we discuss a greedy attempt to find the shortest commo... WebAbstract. For aligning DNA sequences that differ only by sequencing errors, or by equivalent errors from other sources, a greedy algorithm can be much faster than traditional dynamic programming approaches and yet produce an alignment that is guaranteed to be theoretically optimal. We introduce a new greedy alignment algorithm with particularly ... greenies richland washington
