( #3333=superdoc: print w/replies, xml ) Need Help??

My first try at golf:

sub b { $M = scalar keys %t; $m = $M *= $M; foreach ( keys %t ) { $r = c( $_ ); ($m,$n) = ($r, $_) if ($r < $m ); } $n; } sub c { @s=@_; %b = ( $s[0] => $b=$sum=0 ); while ( @s > 0 ) { $b ++; @s = grep { ! exists( $b{$_} ) } map { @{$t{$_}} } @s; @b{ @s } = ($b) x scalar(@s); $sum += $b * scalar(@s); return $M if $sum > $m } $sum; }

works for graphs too, I think.

Update: I can write that down in 196:

sub b{$M=$m=@_*@_;for(keys %t){$r=c($_);($m,$n)=($r,$_)if($r<$m)}$n}su +b c{%b=($_[0]=>$b=$sum=1);while(@_){$b++;@_=grep{!$b{$_}}map{@{$t{$_} +}}@_;@b{@_}=($b)x@_;$sum+=$b*@_;return$M if$sum>$m}$sum}

slower but shorter: down to 177:

sub b{$M=$m=@_*@_;for(keys %t){$r=c($_);($m,$n)=($r,$_)if($r<$m)}$n}su +b c{%b=($_[0]=>$b=$sum=1);while(@_){$b++;@_=grep{!$b{$_}}map{@{$t{$_} +}}@_;@b{@_}=($b)x@_;$sum+=$b*@_}$sum}

I never new how hard obfuscation is! </code>

    [Corion]: You'll only ever need that option if you have a long-running query whose results are not cached by your DB already, and in those cases I presume that the programmer will want to maintain the temporary tables themselves - I wouldn't know when to drop ...
    [Corion]: ... the temporary tables, and also don't have a good idea on how to create unique table names for them
    [hippo]: OIC. In that case leave it out but invite feature requests and see if any of the users suggest it. :-)
    [Corion]: Talking about this makes me realize that it's likely only a half useful idea. But it still would be convenient to have as an option...
    [Corion]: hippo: Hmmm - yeah, I could document it and wait for code implementing that option to show up ;-D
