On C2-smooth Surfaces of Constant Width. (2009)
Journal Article
Guilfoyle, B., & Klingenberg, W. (2009). On C2-smooth Surfaces of Constant Width. Tbilisi Mathematical Journal, 2, 1-17

In this paper, we obtain a number of results for C2-smooth surfaces of constant width in Euclidean 3-space E3-. In particular, we establish an integral inequality for constant width surfaces. This is used to prove that the ratio of volume to cubed wi... Read More about On C2-smooth Surfaces of Constant Width..

We present a polynomial-time algorithm for finding an optimal set of taxa that maximizes the weighted sum of the phylogenetic diversity across two phylogenetic trees. This resolves one of the challenges proposed as part of the Phylogenetics Programme... Read More about Optimizing phylogenetic diversity across two trees.

Consistency of Topological Moves Based on the Balanced Minimum Evolution Principle of Phylogenetic Inference (2009)
Journal Article
Bordewich, M., Gascuel, O., Huber, K., & Moulton, V. (2009). Consistency of Topological Moves Based on the Balanced Minimum Evolution Principle of Phylogenetic Inference. IEEE/ACM Transactions on Computational Biology and Bioinformatics, 6(1), 110-117. https://doi.org/10.1109/tcbb.2008.37

Many phylogenetic algorithms search the space of possible trees using topological rearrangements and some optimality criterion. FastME is such an approach that uses the balanced minimum evolution (BME) principle, which computer studies have demonstra...
