[SOLVED] Finding connected components in a graph.
|
Can't Post
|
|
I have two arrays having the connection information "from -->to"
@a=a,b,d
@b=c,c,e
The following code finds the connected components based on the content of these two arrays.
my @a=qw(a b d);
my @b=qw(c c e);
my $g = Graph->new( undirected => 1 );
for (my $r = 0; $r <= 2; $r++) {
$g->add_edge($a[$r], $b[$r]);
}
my @subgraphs = $g->connected_components;
my $V = $g->vertices;
print "\n$V\n";
print "----connected components------------";
use YAML; print Dump \@subgraphs;
----connected components---------------
-
- c
- a
- b
-
- e
- d
My question is how do I access only one of the connected components? I.e. either C-A-B or D-E
