Abstract

The R+−F+−Consistency problem takes as input two sets R+and R−of resolved triplets and two sets F+and F−of fan triplets, and asks for a distinctly leaf-labeled tree that contains all elements in R+∪ F+and no elements in R−∪ F−as embedded subtrees, if such a tree exists. This paper presents a detailed characterization of how the computational complexity of the problem changes under various restrictions. Our main result is an efficient algorithm for dense inputs satisfying R−= ∅ whose running time is linear in the size of the input and therefore optimal.
