Data on the solution and processing time reached when constructing a phylogenetic tree using a quantum-inspired computer [PDF]
Data in Brief, 2023 Phylogenetic trees provide insight into the evolutionary trajectories of species and molecules. However, because (2n-5)! Phylogenetic trees can be constructed from a dataset containing n sequences, but this method of phylogenetic tree construction is not

The identifiability of tree topology for phylogenetic models, including covarion and mixture models [PDF]
, 2005 For a model of molecular evolution to be useful for phylogenetic inference, the topology of evolutionary trees must be identifiable. That is, from a joint distribution the model predicts, it must be possible to recover the tree parameter.

A Metric on Phylogenetic Tree Shapes [PDF]
Systematic Biology, 2016 The shapes of evolutionary trees are influenced by the nature of the evolutionary process, but comparisons of trees from different processes are hindered by the challenge of completely describing tree shape.

On the Matrix Condition of Phylogenetic Tree. [PDF]
Evol Bioinform Online, 2020 Phylogenetic comparative analyses use trees of evolutionary relationships between species to understand their evolution and ecology. A phylogenetic tree of n taxa can be algebraically transformed into an n by n squared symmetric phylogenetic covariance matrix C where each element [Formula: see text] in C represents the affinity between extant species ...

Characterization of a Branch of the Phylogenetic Tree [PDF]
Journal of Theoretical Biology, 2005 We use a combination of analytic models and computer simulations to gain insight into the dynamics of evolution. Our results suggest that certain interesting phenomena should eventually emerge from the fossil record. For example, there should be a ``tortoise and hare effect'': Those genera with the smallest species death rate are likely to survive much

Locating a tree in a phylogenetic network [PDF]
arXiv, 2010 Phylogenetic trees and networks are leaf-labelled graphs that are used to describe evolutionary histories of species. The Tree Containment problem asks whether a given phylogenetic tree is embedded in a given phylogenetic network. Given a phylogenetic network and a cluster of species, the Cluster Containment problem asks whether the given cluster is a ...

Drawing Phylogenetic Trees [PDF]
, 2005 We present linear-time algorithms for drawing phylogenetic trees in radial and circular representations. In radial drawings given edge lengths (representing evolutionary distances) are preserved, but labels (names of taxons represented in the leaves) need to be adjusted, whereas in circular drawings labels are perfectly spread out, but edge lengths ...

Journal of Software for Algebra and Geometry, 2021 We introduce the package PhylogeneticTrees for Macaulay2 which allows users to compute phylogenetic invariants for group-based tree models. We provide some background information on phylogenetic algebraic geometry and show how the package PhylogeneticTrees can be used to calculate a generating set for a phylogenetic ideal as well as a lower bound for ...

Embedding phylogenetic trees in networks of low treewidth [PDF]
Discrete Mathematics & Theoretical Computer Science, 2023 Given a rooted, binary phylogenetic network and a rooted, binary phylogenetic tree, can the tree be embedded into the network? This problem, called \textsc{Tree Containment}, arises when validating networks constructed by phylogenetic inference methods ...
