Algorithms for the Majority Rule (+) Consensus Tree and the Frequency Difference Consensus Tree

Abstract
En 中文
This article presents two new deterministic algorithms for constructing consensus trees. Given an input of k 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 Omega(kn), and the second one constructs the frequency difference consensus tree in min {O(kn(2)); O(kn(k + log(2) n))} time.
