<Dave> (SPOILER) I'm glad you found that quite quickly, Jim! We'll call it a lucky accident. I thought I had thoroughly tested, clearly not thoroughly enough. Not worried about the solution because this is a classic puzzle, like solitaire (one-left), nim, and many others, the solutions are out there. It was great fun to implement and I was absolutely determined to do it in way which resulted in an orthagonal d-map (nearly). Credit to N7 for finally providing the inspiration and motivation. I could resist building in a 'Clocking Out' type counter. The count used won't help there .). Not sure what to do next ... P.S. I have tried a number of variations of the Rook's Tour idea but so far all have trivial solutions.
Rook's Tour (Full Implementation)	Wed 27 Nov 2013 18:01
<Dave> 'Rook's Tour (Full Implementation)' uploaded by Dave: An implementation of the classic Maximal Rook's Tour (or Arrow Tour) problem. Move a rook around a chess board in a re-entrant tour visiting every square once. A square is 'visited' if you stop and change direction on it. Once visited any attempt to stop on it again will be fatal but it can be passed over safely. The only catch is you have to find the longest possible route (330 for 8x8). Fixed.
Rook's Tour (Full Implementation)	Wed 27 Nov 2013 17:54
<Dave> Moved to graveyard: Thank's Jim. Fortunately a small error rather than a fundamental problem with the mechanism. Fix coming. I'm also changing red to blue for the chequer effect. I'm not sure this is a necessary precaution but just in case ... Besides it gives you a very visual indication when a move has been made. <Jim> (SPOILER) Added solution "Untitled": Sorry Dave, I found a loophole accidently, I uploaded it to show you. This was an amazing implementation, I can't imagine how long it took to do. Maybe you can fix it. <Dave> 'Rook's Tour (Full Implementation)' uploaded by Dave: An implementation of the classic Maximal Rook's Tour (or Arrow Tour) problem.

Once 'visited' any attempt to stop on it again is fatal but it can be passed over safely. The only catch is you have to find the longest route possible. There are mathematical proofs of the length of the maximal route (330 for 8x8) but none regarding the number of different solutions that I am aware of.

<N7DOT> My reversal detecting mechanism required one mechanism for each of horizontal and vertical, so it required 3 mechanisms still. <Dave> (SPOILER) N7, I haven't figured out your dalek/teleport direction reversal detector but don't worry about uploading it just yet, I have found another way. I now have three separate mechanisms: one which only triggers on horizontal reversal, one only on vertical reversal, and the third only on either change of axis; each of these requires 3 bots, that leaves me with 6 bots and loads of space... it 'should' be enough.

<N7DOT> (SPOILER) Dave, you got me! (no idea how to improve that, not enough space to move the steel efficiently) <Dave> (SPOILER) Added speedrun: 110 moves (old: 112).

<mark> (SPOILER) Nice run Dave i was hoping i'd stopped being so blind to the obvious but not so. I'm sure you can improve improv,how about a number 3. I was kind of treating this level like a new series as N7 hinted.

<Dave> (SPOILER) Added speedrun: 223 moves (old: 233). <Dave> (SPOILER) Added speedrun: 233 moves (old: 534). <mark> 'Improv 2' uploaded by mark: A bit more fun.

<Gil Anthony> very nice level make more....

<Dave> (SPOILER) Mark, that is the second solution I mentioned earlier. Nice job finding both! I won't go into it any more details about how many ways there are to do each of the three counts because that is a big spoiler in the right hands. Suffice to say, you've got this well sussed.

<mark> (SPOILER) Very nice level Dave,very satisifying when you find the last number needed.(blue for me). I found 15 different counts between 49 and 100 before solving not looking anymore. Never came up with any logical way to work the out the count just brute force. Uploaded my solution but you probably already knew that. Found a few different ways to find some of the other numbers,but only 1 for red and blue. Not to sure with the eight, might be a bit mean but it is very solvable if you want to do it. Thanks look foward to your next.
