Figure 1

A visual comparison of three tree spaces previously used. The graph structure induced by TBR (a) moves is highly connected. The geodesic structure (b) consists of tiles of Euclidean space (orthants) each consisting of one topology with all its possible branch lengths. These tiles are joined together along their edges in accordance with valid p-ECR moves. Finally Multidimensional Scaling (MDS) (c) plots trees in locations that preserves some distance metric. A typical search is shown where a long tail of trees is followed by a larger group of topologically similar trees.
