Exploring the tiers of rooted phylogenetic network space using tail moves
Remie Janssen, Mark Jones, Péter L. Erdős +2
Popular methods for exploring the space of rooted phylogenetic trees use rearrangement moves such as rNNI (rooted Nearest Neighbour Interchange) and rSPR (rooted Subtree Prune and…

Cycle killer... qu'est-ce que c'est? On the comparative approximability of hybridization number and directed feedback vertex set
Steven Kelk, Leo van Iersel, Nela Lekic +3
We show that the problem of computing the hybridization number of two rooted binary phylogenetic trees on the same set of taxa X has a constant factor polynomial-time approximation…
