Encoding level-k phylogenetic networks

Phylogenetic networks are used to describe evolutionary histories and are a generalisation of evolutionary trees. They can contain so called reticulations, representing reticulate evolution, such as hybridization, lateral gene transfer and recombination. Methods are being developed to construct certain rooted phylogenetic networks from their...

Measuring how far a nonbinary phylogenetic network is from being tree-based

In computational biology, phylogenetic trees are used to describe evolutionary history. This can be done more generally using phylogenetic networks, which can also describe nontreelike events such as hybridization. Some phylogenetic networks can be obtained from a base tree, a rooted spanning tree with the same leaf set, by adding linking edges....
