NAME

       Graph::Maker::SmallWorldWS - Creates a small-world graph according to (Newman) Watt and
       Strogatz

VERSION

       Version 0.01

SYNOPSIS

       Creates a small world graph according to (Newman and) Watt and Strogatz's 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::SmallWorldWS;

               my $g = new Graph::Maker('small_world_ws', N => 10, K => 2, PR => .1, undirected => 1);
               my $g2 = new Graph::Maker('small_world_ws', N => 10, K => 2, PR => .1, keep_edges => 1, undirected => 1);
               # work with the graph

FUNCTIONS

   new %params
       Creates a small world graph with N nodes, K initial connections, and a probability of
       rewiring of PR according to Watts and Strogats.  The recognized parameters are N, K, PR,
       graph_maker, and keep_edges any others are passed onto Graph's constructor.  If N is not
       given it defaults to 0.  If K is not given it defaults to 0.  If PR is not given it
       defaults to 0.  keep_edges uses the Newman, Watts and Strogatz model where "rewiring" adds
       an edge between two random nodes, instead of removing and then adding.  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.
