Abstract. Leaf-labelled trees are widely used to describe evolutionary relationships, particularly in biology. In this setting, extant species label the leaves of the tree, while the internal vertices correspond to ancestral species. Various techniques exist for reconstructing these evolutionary trees from data, and an important problem is to determine how "far apart" two such reconstructed trees are from each other, or indeed from the true historical tree. To investigate this question requires… 
A rearrangement distance for fully-labelled trees
TLDR
This paper provides a rearrangement distance measure between two fully-labelled trees, and shows that it is fixed-parameter tractable, and gives a 4-approximation algorithm when one of the trees is binary.
Extremal Distances for Subtree Transfer Operations in Binary Trees
TLDR
It is shown that for a pair of leaf-labelled binary trees with n leaves, the maximum number of such moves required to transform one into the other is n-Theta (n-Θ(n), extending a result of Ding, Grünewald, and Humphries.
28 : 2 A Rearrangement Distance for Fully-Labelled Trees
TLDR
This paper provides a rearrangement distance measure between two fully-labelled trees, and shows that it is fixed-parameter tractable, and gives a 4-approximation algorithm when one of the trees is binary.
Computing nearest neighbour interchange distances between ranked phylogenetic trees
TLDR
This paper provides the first example of a phylogenetic tree rearrangement operation for which shortest paths, and hence the distance, can be computed efficiently and scales to trees with tens of thousands of leaves.
A 3-factor approximation algorithm for a Minimum Acyclic Agreement Forest on k rooted, binary phylogenetic trees
TLDR
This paper shows that the MAAF for k(>= 2) phylogenetic trees can be approximated to within a factor of 3, and improves this ratio to 3.5.

Reflections on kernelizing and computing unrooted agreement forests
TLDR
This work explores the practical impact of kernelization (i.e. data reduction) on the NP-hard problem of computing the TBR distance between two unrooted binary phylogenetic trees and finds that the new rules yield smaller reduced instances and thus have clear practical added value.
SPR Distance Computation for Unrooted Trees
TLDR
The method is a heuristic version of a fixed parameter tractability (FPT) approach and the running time behaves similar to FPT algorithms, and was able to quickly compute dSPR for the majority of trees that were part of a study of LGT in 144 prokaryotic genomes.
Neighborhoods of Trees in Circular Orderings
TLDR
It is shown that the size of such a neighborhood of a binary tree associated with the nni operation is independent of the tree’s topology, but that this is not the case for the spr and tbr operations.

The discovery and importance of multiple islands of most
TLDR
The set of most-parsimonious trees for a data matrix may include several distinct classes (islands) of trees, and trees in different islands may have different implications for character evolution, and for this reason should be sought.
