WebJoin cannot compete with QuickTree on small data sets. Other approaches, such as \relaxed neighbour-joining" [3,10] and \fast neighbour-joining" [1] modify the optimisation criteria used when selecting pairs to join. The method \relaxed neighbour-joining" has a worst-case O n3 running time while \fast neighbour-joining" has O n2 running time.
