Abstract

This article presents two new deterministic algorithms for constructing consensus trees. Given an input of κ phylogenetic trees with identical leaf label sets and n leaves each, the first algorithm constructs the majority rule (+) consensus tree in O(kn) time, which is optimal since the input size is ω (kn) , and the second one constructs the frequency difference consensus tree in μ\lbrace O(kn2), O(kn (k+log2n)) time.
