   What is the BLAST algorithm?

   • In order to increase the speed of alignment, the BLAST algorithm was designed to approximate the results of an alignment algorithm created by Smith and Waterman (1981), but to do so without comparing each residue against every other residue (Altschul et al ., 1990).
