关于点、边和点边随机图

On vertex, edge, and vertex-edge random graphs

Elizabeth Beer, James Allen Fill, Svante Janson, Edward R. Scheinerman

摘要:

我们考虑三类随机图:边随机图,顶点随机图和顶点-边随机图。边随机图是Erdos-Renyi随机图,点随机图是几何随机图的推广,点边随机图是几何随机图的推广。这三种类型的随机图的名称描述了模型中的随机性所在:在边中,在顶点中,或者在两者中。我们表明,顶点边随机图,表面上最一般的三种模式,可以任意接近顶点随机图,但这两类是不同的。

英文摘要:

We consider three classes of random graphs: edge random graphs, vertex random graphs, and vertex-edge random graphs. Edge random graphs are Erdos-Renyi random graphs, vertex random graphs are generalizations of geometric random graphs, and vertex-edge random graphs generalize both. The names of these three types of random graphs describe where the randomness in the models lies: in the edges, in the vertices, or in both. We show that vertex-edge random graphs, ostensibly the most general of the three models, can be approximated arbitrarily closely by vertex random graphs, but that the two categories are distinct.
