WebThe algorithm can be slow. 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. TEST DATA SET 5 WebPhylogenetics Distance Methods - Rice University
