Making phylogenetic networks orchard: Algorithms to determine if a phylogenetic network is orchard and to transform non-orchard to orchard networks

Phylogenetic networks are used to represent evolutionary histories of a set of taxa. In this thesis, we look at a certain network class, called orchard networks. <br/>In the beginning of this thesis, definitions concerning phylogenetic networks and specifically orchard networks are introduced. The characterization of orchard networks involves...

Constructing level-2 phylogenetic networks from trinets

Phylogenetic networks are a generalization of evolutionary trees that can be used to represent reticulate events. Level-k phylogenetic networks are such networks, but with a at most k reticulations per biconnected component of the network. For level-1 networks there exists an algorithm, called TriLoNet (Trinet Level-one Network algorithm), that...

Resolving contradicting binets and finding similarities in networks

To understand the (physical) differences between species, biologist research the common ancestry of these species. This research area is called phylogenetics and the visualisation of the ancestry is displayed with the use of phylogenetic trees or networks. Generally, the phylogenetic networks are not known completely or with certainty. Therefore...
