NAME
       Graph::Maker::Random - Creates a random graph (using Erdos Renyi or with a specified number of edges)


VERSION
       Version 0.01


SYNOPSIS
       Creates a random graph with N nodes and with exactly M edges or connects random edges with probability
       PR.  A random graph has N nodes and M random edges, OR for every pair of nodes adds an edge with
       probability PR (Erdos-Renyi graph).  If the graph is directed then edges are added in both directions to
       create an undirected graph.

               use strict;
               use warnings;
               use Graph;
               use Graph::Maker;
               use Graph::Maker::Random;

               my $g = new Graph::Maker('random', N => 10, M => 2, undirected => 1);
               my $g = new Graph::Maker('random', N => 100, PR => .01, undirected => 1);
               # work with the graph


FUNCTIONS
   new %params
       Creates a random graph with N nodes either connecting edges with the given probability (PR) or with the
       specified number of edges (M); The recognized parameters are graph_maker, N, M, and PR any others are
       passed onto Graph's constructor.  If N is not given it defaults to 0.  If PR is not given it defaults to
       0.  If PR is 1 or M is bigger than N*(N-2)/2 then returns a Complete Graph.  If M is not given it
       defaults to 0.  If PR and M are both nonzero ignores M.  If graph_maker is specified it will be called to
       create the Graph class as desired (for example if you have a subclass of Graph), this defaults to create
       a Graph with the parameters specified.
