NAME

       Graph::Maker::Uniform - Creates a graph distributed randomly over the d-dimensional grid.

VERSION

       Version 0.01

SYNOPSIS

       Creates a uniform graph with nodes distributed randomly over dims-dimensional unit cube.
       A uniform graph distributes nodes randomly (generally uniformally) over a unit cube in
       some number of dimensions, where nodes are connected iff they are with rad units of
       distnace of eachother and no nodes are within repel distance of eachother.  If the graph
       is directed then edges are added in both directions to create an undirected graph.

               use Graph;
               use Graph::Maker;
               use Graph::Maker::Uniform;
               use Math::Random::Free qw/random_normal/;

               my (@a, @b);
               @a = (2); @b = (1,1);
               $g = new Graph::Maker('uniform', N => 100, radius => 0.1, undirected => 1);
               @a = (2,3,1,2,1); @b = (2,2,1,3,1);
               $g2 = new Graph::Maker('uniform',
                       N => 100,
                       rad => 0.15,
                       dims => 3,
                       repel => 0.01,
                       random => sub { random_normal($_[0], 0, 0.5) }
               ); # make the nodes distributed over the cube with a gaussian (normal) distribution
               # work with the graph

FUNCTIONS

   new %params
       Creates a uniform graph with N nodes randomly distributed over a dims-dimensional unit
       cube, where nodes are connected if they are within rad euclidian (L2) units of distance,
       and no nodes are within repel distance of eachother according to the random distribution.
       The recognized parameters are N, rad, dims, repel, graph_maker, and random.  any others
       are passed onto Graph's constructor.  If N is not given it defaults to 0.  if rad is not
       given it defaults to 0.  If dims is not given it defaults to 2.  If repel is not given it
       defaults to 0.  if random is not given it defaults to uniform
       (Math::Random::Free::random_uniform(dims, 0, 1)), if random is given it is passed the
       number of random numbers that should be returned.  The vertex attribute pos will be set to
       an array reference of the nodes d-dimensional position.  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.
