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…
Monotone Arc Diagrams with few Biarcs
Steven Chaplick, Henry Förster, Michael Hoffmann +1
We show that every planar graph has a monotone topological 2-page book embedding where at most (4n-10)/5 (of potentially 3n-6) edges cross the spine, and every edge crosses the spi…
Approximation Ratio of the Min-Degree Greedy Algorithm for Maximum Independent Set on Interval and Chordal Graphs
Steven Chaplick, Martin Frohn, Steven Kelk +2
In this article we prove that the minimum-degree greedy algorithm, with adversarial tie-breaking, is a -approximation for the Maximum Independent Set problem on interval gra…
