Graph::Maker::Utils(3pm)

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.
