Definition

Glossary of "Cladistics (2nd ed.)" by Kitching et al. (1998)

• The optimization procedure used for a certain type of ordered, polarized, directed character. The costs of the transformations, 0 -> 1, 1-> 2, etc., are as in Wagner optimization. The costs of all transformations in the opposite direction are treated as infinite, thereby preventing character reversal. Camin-Sokal optimization requires all homoplasy to be accounted for by multiple, parallel transformations.
