Weblosses. To illustrate the mechanics of parsimony reconstruction, the formal algorithm for Fitch parsimony for unordered states is provided on the last two pages. Note: In … Webuse Fitch's algorithm to generate the sets and total cost of 4 as shown. If m > 1, then Fitch's algorithm can be applied independently to each site in the sequence, and the tree scores per site can be summed to get the total score. Large parsimony problem given sequence data, find minimum-score tree with leaves labeled by seqs.
