Fast Fitch-Parsimony Algorithms for Large Data Sets
WebJul 26, 2024 · This algorithm is based on the CF (clustering features) tree. In addition, this algorithm uses a tree-structured summary to create clusters. The tree structure of the given data is built by the BIRCH algorithm called the Clustering feature tree(CF tree). In context to the CF tree, the algorithm compresses the data into the sets of CF nodes. 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… WebFeb 7, 2009 · Background Parsimony methods are widely used in molecular evolution to estimate the most plausible phylogeny for a set of characters. Sankoff parsimony determines the minimum number of changes required in a given phylogeny when a cost is associated to transitions between character states. Although optimizations exist to reduce the … raya stream free
