  1. Maximum parsimony (phylogenetics) - Wikipedia

    • In phylogenetics and computational phylogenetics, maximum parsimony is an optimality criterion under which the phylogenetic tree that minimizes the total number of character-state changes (or minimizes the cost of differentially weighted character-state changes). Under the maximum-parsimony criterion, the optimal tree will minimize the amount of homopla… See more

    Alternate characterization and rationale

    In phylogenetics, parsimony is mostly interpreted as favoring the trees that minimize the amount of … See more

    In detail

    Parsimony is part of a class of character-based tree estimation methods which use a matrix of discrete phylogenetic characters and character states to infer one or more optimal phylogenetic trees for a set of taxa, commonly … See more

    Character data

    The input data used in a maximum parsimony analysis is in the form of "characters" for a range of taxa. There is no generally agreed-upon definition of a phylogenetic character, but operationally a character c… See more
