WebWalter Monroe Fitch (May 21, 1929 – March 10, 2011) was a pioneering American researcher in molecular evolution. ... He also developed the Fitch maximum parsimony algorithm, which evaluates rapidly and exactly the minimum number of changes of state of a sequence on a given phylogeny. WebThe algorithm can be slow. As the number of species rises, so does the number of distances from each species to the others. The speed of this algorithm will thus rise as the fourth power of the number of species, rather than as the third power as do most of the others. Hence it is expected to get very slow as the number of species is made larger.
