Gelntlemen, please post your code. The public round has now started and it'll be a free-for-all. So, hack away at your opponents code.

I hope everybody did their research before actuallly coding. If not, your fault. Otherwise, you would have come across the following article The Shuttle Puzzle – A Lesson in Problem Solving . The article contains a complete analysis of the puzzle, the embedded rules for the algorithm, and, yes, the algorithm itself, ready to be translated to KiXtart

Let the games (second part) begin...

Here's my still very golf-able 249 code. For the record, i came up with my algorithm soley based on Jooel's post of the solutions in the private round, so thanks Jooel

Code:

function s($a)
   dim $,$i,$c,$n
   $=' '
   for $c = 1 to $a
      $ = 'Wa' + $ + 'aB'
   next
   $ = split($,a)
   $s=join($,'')

   $n=1
   for $i = 1 to $a*2
      for $c=$n*($i-2*($i-$a)*($i>$a))*($i<$a*2) to -$c step -2*$n
         $[ascan($,' ')] = $[$c+$a]
         $[$c+$a]=' '
         $s=$s+a+join($,'')
      next
      $n=-$n
   next
   $s=split($s,a)
endfunction

I'm leaving for Vegas today, so i'll catch you guys again on Wednesday. Good luck!

and here's my 308:
Code:

Function s($i)
dim $d,$,$_,$k,$t

  $ = " "
  for $_=1 to $i $=W + $ + B next
  $t=$

 for $i=6 to 9
   if $i>5 $_=$_<1 endif
   for $k=1 to 2
     $d = instr($," ")
     if iif($_,W,B)=substr($,$d+$k-2*$_*$k,1) & ($_ ^ W=substr($,$d-1+2*$_,1)) | $i>5
       $i = "B "," W","BW "," BW"
       $ = left($,$d-1-$_*$k) + $i[2*(1<$k)+$_] + substr($,$d+1+$k-$k*$_)
       $t = $t + ! + $
       $s = split($t,!)
       $i = 0
EndFunction

[edit]
found out that my tester was corrupt. thus this code does work and 245 is the leading score.
[/edit]
but if it does work on some other kixtart version, here is 245

Code:

function s($a)
   dim $,$i,$c,$n
   $=' '
   for $c = 1 to $a
      $ = Wa + $ + aB
   next
   $ = split($,a)
   $s=join($,'')

   $n=1
   for $i = 1 to $a*2
      for $c=$n*($i-2*($i-$a)*($i>$a))*($i<$a*2) to -$c step -2*$n
         $[ascan($,' ')] = $[$c+$a]
         $[$c+$a]=' '
         $s=$s+a+join($,'')
      next
      $n=-$n
   next
   $s=split($s,a)
endfunction

had commented out the valid lines when wanted to quickly test possible shorter resolutions

so, your code indeed worked fine.
sorry.

By the way, i didn't read the link jens posted, but if you look at the position of the space ' ' with regards to the center of board, a pretty clear pattern appears. Here are those positions for $=1 to 5

Quote:


1 -1 0
1 -1 -2 0 2 1 -1 0
1 -1 -2 0 2 3 1 -1 -3 -2 0 2 1 -1 0
1 -1 -2 0 2 3 1 -1 -3 -4 -2 0 2 4 3 1 -1 -3 -2 0 2 1 -1 0
1 -1 -2 0 2 3 1 -1 -3 -4 -2 0 2 4 5 3 1 -1 -3 -5 -4 -2 0 2 4 3 1 -1 -3 -2 0 2 1 -1 0

btw, nice to see you got rid of those darn substr()'ngs

my head was too deep in the bushes to find out the correct array patterns.
I thought there was no way to get it shorter with arrays so never cared to even look that way.

Arggghhh ... And I thought the end was at 3:00 PM (GMT+1) not 1:00 PM

I just came back from doing the weekend shopping, changed the direction of my loop a bit and got a working code (518 though, but hey)

Ok here's my 279 code, dont have time right now to golf, but maybe tommorow.

Code:

Function s($)
Dim $a,$b,$c,$d,$e,$f,$g
$d=" "
For $b=1 to $
	$d="W"+$d+"B"
	$a=$a+$+2
Next
Redim $s[$a]
$=2
For $c=0 to $a
	$s[$c]=$d
	$d=Join(Split($d),SubStr($d,$b-1,1))
	$d=Left($d,$b-2)+" "+substr($d,$b)
	$b=$b+$
	$e=Iif($a/2>$c+1,1,~)
	If Abs($)=1
		$=-2*$e*$
	Else
		If $f
			$f=$f-1
		Else
			$=$*$e/2
			$g=$g+$e
			$f=$g
EndFunction

Corrected the link. Will run the scripts through validation later today.

And anybody who plays a round of KiXgolf deserves to be more than a Stranger/Newbie
