Important: The networks package has been deprecated .Use the superseding command GraphTheory[RandomGraphs] instead.

This procedure generates a variety of different types of random graphs. If only one argument n is specified, this is taken to be the number of vertices, and each edge of the complete graph on n vertices is assumed to be present with a probability of 1/2.

Extra arguments can be used to specify the number of edges m or the specific independent probability x with which a given edges occurs.

If m is specified, a random n-vertex m-edge simple undirected graph is constructed.

If x is specified, each undirected edge is chosen for inclusion "independently" with probability x.

This routine is normally loaded by using the command with(networks), but it may also be referenced by using the full name networks[random](...).
