A kernel for the maximum agreement forest problem on multiple binary phylogenetic trees

Steven Kelk, Ruben Meuwese, Leo van Iersel

The maximum agreement forest (MAF) problem in phylogenetics takes as input a set t >= 2 of binary phylogenetic trees T on the same set of taxa X. It asks for a partition of X into…

Computational support for case-heavy proofs in mathematical phylogenetics

Luca Forte, Leo van Iersel, Steven Kelk +1

In this note we demonstrate that a number of case-heavy combinatorial proofs in the mathematical phylogenetics literature can be proven more compactly using computational support.…

Split-or-decompose: Improved FPT branching algorithms for maximum agreement forests

David Mestel, Steven Chaplick, Steven Kelk +1

Phylogenetic trees are leaf-labelled trees used to model the evolution of species. In practice it is not uncommon to obtain two topologically distinct trees for the same set of spe…

Relaxed Agreement Forests

Virginia Aardevol Martinez, Steven Chaplick, Steven Kelk +3

There are multiple factors which can cause the phylogenetic inference process to produce two or more conflicting hypotheses of the evolutionary history of a set X of biological ent…

Agreement forests of caterpillar trees: complexity, kernelization and branching

Steven Kelk, Ruben Meuwese

Given a set of species, a phylogenetic tree is an unrooted binary tree whose leaves are bijectively labelled by . Such trees can be used to show the way species evolve over…

Snakes and Ladders: a Treewidth Story

Steven Chaplick, Steven Kelk, Ruben Meuwese +2

Let be an undirected graph. We say that contains a ladder of length if the grid graph is an induced subgraph of that is only connected to the rest…

Deep kernelization for the Tree Bisection and Reconnnect (TBR) distance in phylogenetics

Steven Kelk, Simone Linz, Ruben Meuwese

We describe a kernel of size 9k-8 for the NP-hard problem of computing the Tree Bisection and Reconnect (TBR) distance k between two unrooted binary phylogenetic trees. We achieve…

Cyclic generators and an improved linear kernel for the rooted subtree prune and regraft distance

Steven Kelk, Simone Linz, Ruben Meuwese

The rooted subtree prune and regraft (rSPR) distance between two rooted binary phylogenetic trees is a well-studied measure of topological dissimilarity that is NP-hard to compute.…

Convex characters, algorithms and matchings

Steven Kelk, Ruben Meuwese, Stephan Wagner

Phylogenetic trees are used to model evolution: leaves are labelled to represent contemporary species ("taxa") and interior vertices represent extinct ancestors. Informally, convex…

Sharp upper and lower bounds on a restricted class of convex characters

Steven Kelk, Ruben Meuwese

Let be an unrooted binary tree with distinctly labelled leaves. Deriving its name from the field of phylogenetics, a convex character on is simply a…
