Fitch is noted for his pioneering work on reconstruction of phylogenies (evolutionary trees) from protein and DNA sequences. Among his achievements are the first major paper on distance matrix methods, which introduced the Fitch–Margoliash method (with Emanuel Margoliash) which seeks the tree that best predicts a set of pairwise distances among species. He also developed the Fitch maximum parsimony algorithm, which evaluates rapidly and exactly the minimum number of cha…

WebOct 2, 2024 · The text is organized as follows. In Sect. 2, we propose a genetic algorithm for the large live parsimony problem, using algorithms to solve the small live parsimony problem. For this last one, we extended the algorithms of Fitch and Sankoff to deal with live phylogenies.
