WebApr 12, 2024 · Wednesday, April 12, 2024 The Fitch algorithm for computing the parsimony score of a character, in R The simplest way to compute the parsimony score of a discrete character on the tree is by using a method called the Fitch algorithm, and named after Walter Fitch. WebMay 2, 2012 · Maximum Parsimony is a character-based approach that infers a phylogenetic tree by minimizing the total number of evolutionary steps required to explain a given set of data assigned on the leaves. Exact solutions for optimizing parsimony scores on phylogenetic trees have been introduced in the past. ... such as Sankoff and Fitch …
