Summary
We point out that a tree dissimilarity t is entirely defined by its restriction to a set B of 2n - 3 entries, easily determined from the table of t and including the n - 1 entries of a minimum spanning tree (MST). A method for the adjustment of a tree dissimilarity to any given dissimilarity d is derived from this result. This fitting method preserves an MST of d and leads to a fast algorithm. The proofs of the results given here and more information may be found in Leclerc (1993).
