tall man is right, my example is incomplete and incoherent ( it was late), but luckily, you got it exactly, Zaxo.
btw, I do construct the graph, I just missed that in the example, trying to keep it minimal.
One clarification, my input data would look more like:
my @combos = (
[qw(black white)],
[qw(red white)],
[qw(cyan red)],
[qw(yellow blue)],
[qw(magenta green blue)],
[qw(cyan periwinkle raspberry)],
);
so not all the vertices are connected, and in fact what I need to get out of this are the sets that are. so what I do is:
sub r {
my $g = shift;
my $v = shift;
my @ns = $g->neighbors($v);
print $v."\n";
$g->delete_vertex($v);
foreach my $n (@ns){
r($g, $n);
}
}
while (scalar $g->vertices > 0){
print "next set:\n";
r($g, ($g->vertices)[0]);
}
This however doesn't seem terribly elegant (or efficient), am I anywhere near what I should be doing in this case?
and thanks for your great help!
