NAME

       Graph::Maker::SmallWorldBA - Creates a small world graph according to the Barabási-Albert preferential
       attachment model.

VERSION

       Version 0.01

SYNOPSIS

       Creates a small world graph according to the Barabási-Albert model.  A small world graph has an
       approximate power law degree distribution and a high clustering coefficient.  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::SmallWorldBA;

               my $g = new Graph::Maker('small_world_ba', N => 10, M => 2, undirected => 1);
               my $g2 = new Graph::Maker('small_world_ba', N => 10, M => 2, callback => sub {print "Node added\n"}, undirected => 1);
               # work with the graph

FUNCTIONS

   new %params
       Creates a small world graph with N nodes added on M edges at each step (the minimum number of edges per
       node) according to the Barabási-Albert model.  The recognized parameters are N, M, graph_maker, and
       callback any others are passed onto Graph's constructor.  If N is not given it defaults to 0.  If M is
       not given it defaults to 1.  callback allows one to simulate the growth of a preferential attachment
       network, callback will be called each time a node is added.  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.
