Mader proved that for k≥1 and n≥2k, every n-vertex graph with no (k+1)-connected subgraphs has at most (1+12)(n−k) edges. He also conjectured that for n large with respect to k, every such graph has at most 32(k−13)(n−k) edges. Yuster improved Mader’s upper bo...
He also conjectured that for $n$ large with respect to $k$, every such graph has at most $\\\frac{3}{2}\\\left(k - \\\frac{1}{3}ight)(n-k)$ edges. Yuster improved Mader's upper bound to $\\\frac{193}{120}(n-k)$ for $n\\\geq\\\frac{9k}{4}$. In this note...
In communication networks, the edges can be either directed or undirected, depending on the specific problems. Both nodes and edges can be associated with some attributes as the features, either static or dynamic. Two graph examples are given for the wired and wireless scenarios respectively. In ...

Observation 3.1.Any drawing of a graphGwith pairs of edges mutually intersecting more than once, can be redrawn as a good drawing of the same graph with at most as many crossings as the original one. 一些术语的别的叫法 For the sake of clarity, there are a few things to note about the...
Examples include C n and K n,n for n≥2. Finally it is shown that a class 1-graph is also a class 4-graph. But the converse is not true. And also class 5-graphs with no pendant edges are class 4-graphs. The converse fails, too. 展开 年份: 1992 ...

It is known that, for any fixed k , any geometric graph G on n vertices with no k pairwise crossing edges contains at most O ( n log n ) edges. In this paper we give a new, simpler proof of this bound, and show that the same bound holds also when the edges of G are ...
Visualize & explore large graphs:In just a few minutes, create stunning interactive visualizations with millions of edges and many point-and-click built-ins like drilldowns, timebars, and filtering. When ready, customize with Python, JavaScript, and REST APIs. ...
De novo, in-silico design of molecules is a challenging problem with applications in drug discovery and material design. We introduce a masked graph model, which learns a distribution over graphs by capturing conditional distributions over unobserved nodes (atoms) and edges (bonds) given observed on...
