Encoding level-3 semi-directed phylogenetic networks by quarnets and quinnets
Niels Holtgrefe, Katharina T. Huber, Leo van Iersel +1
Phylogenetic networks generalize phylogenetic trees as models of evolutionary history, allowing lineages to merge as well as to diverge. For many types of genetic data the root pos…
On Tree-Network Distinguishability and Full Identifiability of Phylogenetic Networks
Jari Brits, Niels Holtgrefe, Leo van Iersel +1
Phylogenetic networks generalize phylogenetic trees to evolutionary histories that include reticulate events such as recombination, horizontal gene transfer, and hybridization. Und…
Tractable Maximization of Budgeted Phylogenetic Diversity on Networks Utilizing Node Scanwidth
Niels Holtgrefe, Jannik Schestag
Background: Identifying a subset of taxa that maximizes phylogenetic diversity is a cornerstone of quantitative conservation planning. Traditionally, phylogenetic diversity is defi…
Limits of Kernelization and Parametrization for Phylogenetic Diversity with Dependencies
Niels Holtgrefe, Jannik Schestag, Norbert Zeh
In the Maximize Phylogenetic Diversity problem, we are given a phylogenetic tree that represents the genetic proximity of species, and we are asked to select a subset of species of…
