DNAPENNY is a program that will find all of the most parsimonious trees implied by your data when the nucleic acid sequence parsimony criterion is employed. It does so not by examining all possible trees, but by using the more sophisticated branch and bound algorithm, a standard computer science search strategy first applied to phylogenetic inference by Hendy and Penny (1982). (J. S. Farris [personal communication, 1975] had also suggested that this strategy, which is well-known in computer science, might be applied to phylogenies, but he did not publish this suggestion).
