Parsimony optimization of phylogenetic networks
Cladistics, 2023AbstractAn algorithm is described for the optimization of character data (e.g. qualitative, nucleic acid sequence) on softwired phylogenetic networks. The algorithm presented here is an extension of those developed for trees under the parsimony criterion and can form the basis for phylogenetic network search procedures.

The evolutionary history of species is traditionally represented using a rooted phylogenetic tree. However, when reticulate events such as hybridization, horizontal gene transfer or recombination are believed to be involved, phylogenetic networks that can accommodate non-treelike evolution have an important role to play.

Abstract Phylogenetic networks a.re a. generalization of phylogenetic trees that permit the representation of conflicting signal or alternative phylogenetic histories. Networks are clearly useful when the underlying evolutionary history is nontreelike.

Drawing Rooted Phylogenetic Networks
IEEE/ACM Transactions on Computational Biology and Bioinformatics, 2009The evolutionary history of a collection of species is usually represented by a phylogenetic tree. Sometimes, phylogenetic networks are used as a means of representing reticulate evolution or of showing uncertainty and incompatibilities in evolutionary datasets. This is often done using unrooted phylogenetic networks such as split networks, due in part,

Properties of Normal Phylogenetic Networks
Bulletin of Mathematical Biology, 2009A phylogenetic network is a rooted acyclic digraph with vertices corresponding to taxa. Let X denote a set of vertices containing the root, the leaves, and all vertices of outdegree 1. Regard X as the set of vertices on which measurements such as DNA can be made. A vertex is called normal if it has one parent, and hybrid if it has more than one parent.

Reconstructing phylogenetic networks.
2023Phylogenetic networks are a generalization of phylogenetic trees that allow for reticulation. Reconstruction of phylogenetic trees from distances is well studied, but for networks, there are relatively few results. Recent results have focused on restricting the space of phylogenetic networks to speci c subclasses with desirable properties, in ...

Phylogenetic Networks with Every Embedded Phylogenetic Tree a Base Tree
Bulletin of Mathematical Biology, 2015We show that the class of tree-child networks is precisely the class of tree-based networks with the property that every embedded phylogenetic tree is a base tree.
