of every balanced binary tree with 2n vertices , n ⩾ 1, is n. The 2-rooted complete binary tree of depth n is obtained from two copies of the complete binary tree of depth n by adding an edge linking ...
- ning tree , r-critical tree , Cayley graph. Consider a finite connected nonoriented graph Gr = (V ,E) with set of vertices V and set of edges E . For two vertices x, y ∈V ,denoteby d(x, y) the length ...
Pinus sylvestris trees . Filled symbols and solid lines: Tree 1; open symbols and dashed lines: Tree 2. Note the log-scaling of the y-axis. The dashed vertical line indicates the start of 13C label ...
graphs, cycles, trees , and, in fact, almost all graphs, are totally balanced . We prove: • Let H be a dag with h vertices and m edges which is not a rooted star. For every a > ...
A graph G is balanced if the maximum ratio of edges to vertices , taken over all subgraphs of G, occurs at G itself. This note uses the max‐flow/min‐cut theorem to prove a good characterization ...

of stretchable words. We quantify two independent properties of stretchable words: Their ‘ balance ’ in Sec. 3.2 and ‘stretch’ in Sec. 3.3. In Sec. 3.4, we develop an investigative tool, ‘spelling trees ’, as a means ...

with similar topologies. A meta- tree is not itself a phylogeny but is a way of representing the relationships between the original set of alternative phylogenies. The set of leaf vertices on a meta- tree ...
