NAME

       Graph::Maker::SmallWorldHK - Creates a small world graph according to Holmea, Beom & Kim

VERSION

       Version 0.01

SYNOPSIS

       Creates a small world graph according to Holmea, Beom & Kim's model.  A small world graph
       has an approximate power law degree distribution and a high clustering coefficient.
       Holmea, Beom & Kim's can be seen as a super-set of th BA model as it also allows a
       "triangle formation" phase to increase the 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::SmallWorldHK;

               my $g = new Graph::Maker('small_world_hk', N => 10, M => 2, M_0 => 1, PR => 0, undirected => 1); # BA's model
               my $g2 = new Graph::Maker('small_world_hk', N => 10, M => 2, M_0 => 1, PR => 0.25, undirected => 1);
               # work with the graph

FUNCTIONS

   new %params
       Creates a small world graph with N nodes, initially starting with M_0 nodes and adding M
       (the minimum number of edges per node) on each step probalistically doing a triangle
       formation with probability PR according to the Holmes, Beom & Kim model.  The recognized
       parameters are N, M, M_0, PR, 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.  If
       M_0 is not given it defaults to M.  If PR is not given it defaults to 0.  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.
