Robinson-foulds rf distance
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 … WebThe Robinson-Foulds (RF) distance is a well-established measure between phylogenetic trees. Despite a lack of biological justification, it has the advantages of being a proper metric and being computable in linear time. For phylogenetic applications involving genes, however, a crucial aspect of the trees ignored by the RF metric is the type of the branching event …

Webthe RF distance (Robinson and Foulds, 1981), the edges are weighted by 1 (for different clusters) or 0 (for identical clusters). In the b distance (Boorman and Olivier, 1973), which is basically the same as the matching cluster distance of (Bogdanowicz and Giaro, 2012b), each edge is weighted by the size of the symmetric difference of the pair ... WebMay 17, 2024 · The RF distance, also known as the symmetric-difference distance, between two trees is a widely used metric for comparison of phylogenetic trees defined on the same set of taxa (Robinson and Foulds, 1981). The RF distance is a topological distance. It does not take into account the length of the tree edges.

While a large variety of pairwise measures of similarity or dissimilarity have been developed for comparing trees with no information on …
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.
