Robinson-foulds rf distance
WebThe Robinson-Foulds (RF) metric is arguably the most widely used measure of phylogenetic tree similarity, despite its well-known shortcomings: For example, moving a single taxon in a tree can result in a tree that has maximum distance to the original one; but the two trees are identical if we remove the single taxon. http://blog.phytools.org/2013/02/robinson-foulds-distance-and-nni.html

WebOct 4, 2024 · The Robinson-Foulds (RF) metric provides symmetric distance between two phylogenies as a sum of monophyletic groups present in one tree but not in the other. The normalised RF distance is given as $\frac{RF_i}{RF_{max}}$.
WebMay 20, 2024 · The adapted problem, called the Robinson-Foulds reticulation network (RF-Network) problem is, as we show and like many other problems applied in molecular biology, NP-hard. To address this, we employ local search strategies that have been successfully applied in other NP-hard phylogenetic problems. Our local search method benefits from … WebJun 10, 2024 · We generalize the Robinson–Foulds distance into a set of distance metrics called Bourque distances for comparing mutation trees. We show the basic version of the Bourque distance for mutation trees can be computed in linear time. We also make a connection between the Robinson–Foulds distance and the nearest neighbor interchange …
