A Polynomial-Time Algorithm for the Phylogeny
Problem when the Number of Character States is Fixed
Authors: Richa Agarwala and David Fernandez-Baca
ABSTRACT
We present a polynomial-time algorithm for determining whether a
set of species, described by the characters they exhibit, has a
phylogenetic tree, assuming the maximum number of possible states
for a character is fixed. This solves an open problem posed by
Kannan and Warnow. Our result should be contrasted with the proof
by Steel and Bodlaender, Fellows, and Warnow that the phylogeny
problem is NP-complete in general.
