# NAME

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

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.
