Most parsimonious tree

WebMar 26, 2024 · The weighted maximum parsimony analysis revealed only a single most parsimonious tree with a length of 161 steps, a consistency index of 0.56 and a retention index of 0.77. The 50% majority-rule consensus tree inferred by Bayesian inference had a branching pattern identical to the most parsimonious tree and therefore posterior … WebThe branch-and-bound algorithm thus allows us to find all most parsimonious trees without generating all possible trees. How much of a saving this is depends strongly on the data. For very clean (nearly "Hennigian") data, it saves much time, but on very messy data it will still take a very long time. The algorithm in the program differs from ...
