NAME

       Graph::Maker::Utils - Small routines that Graph::Maker::* uses.

VERSION

       Version 0.02

SYNOPSIS

       Some utility functions for Graphs.

               use strict;
               use warnings;
               use Graph::Maker;
               use Graph::Maker::Linear;
               use Graph::Maker::Utils qw/is_valid_degree_seq cartesian_product/;

               my @seq = (2, 1, 1);
               my $bool = is_valid_degree_seq(@seq); # returns true
               my @se2 = (2, 1, 1, 1)
               my $boo2 = is_valid_degree_seq(@se2); # returns false

               my $g1 = new Graph::Maker('linear', N => 10);
               my $g2 = new Graph::Maker('linear', N => 10);
               my $g = cartesian_product($g1, $g2); # returns the 2-dimensional plane

EXPORT

       Nothing by default, specify any set of functions, or :all to import everything.

FUNCTIONS

   cartesian_product $g, $h
       Creates a new graph that is the cartesian product of $g and $h.  For example, the
       cartesian product of two linear graphs is a grid graph.

   is_valid_degree_seq @seq
       Tests if @seq is a valid degree sequence, that is if it can be used to generate a graph.
       This is mainly used in other Graph::Maker packages.
