Cyclic matroids
Nick Brettell, Charles Semple, Gerry Toft
For all positive integers and exceeding one, a matroid on elements is {\em nearly -cyclic} if there is a cyclic ordering of its ground set such that eve…
Counting and optimising maximum phylogenetic diversity sets
Kerry Manson, Charles Semple, Mike Steel
In conservation biology, phylogenetic diversity (PD) provides a way to quantify the impact of the current rapid extinction of species on the evolutionary `Tree of Life'. This appro…
On the Complexity of Optimising Variants of Phylogenetic Diversity on Phylogenetic Networks
Magnus Bordewich, Charles Semple, Kristina Wicke
Phylogenetic Diversity (PD) is a prominent quantitative measure of the biodiversity of a collection of present-day species (taxa). This measure is based on the evolutionary distanc…
Non-essential arcs in phylogenetic networks
Simone Linz, Charles Semple
In the study of rooted phylogenetic networks, analyzing the set of rooted phylogenetic trees that are embedded in such a network is a recurring task. From an algorithmic viewpoint,…
