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. WebThe traditional approach for computing Robinson-Foulds distance between two trees that only have a partially overlapping leaf set is to first restrict the two trees to their shared leaf set and then compute their Robinson-Foulds distance. We refer to distances computed in this way as RF (-) distances.
