<Jim> (SPOILER) Dave, I love the solution to 2.2, it was the hardest to find for me and the best of the series in my opinion. <Dave> (SPOILER) 2.1b is not really the way I would like to see this ultimately go, mark's efforts are truer to the original idea. It's food for thought, cook away... <Dave> (SPOILER) PPS. Please upload any distinctly different solutions to the Rook's problem. The number of solutions is unknown, but they are numerous, so it would be interesting to see how varied they are. <Dave> (SPOILER) PS. Kirima, are you out there? <Dave> (SPOILER) Oh dear (to put politely)! I've just seen the speedrun on 2.2. We have a problem: 2.2 doesn't force the bit I want to force, 2.1a doesn't force the bit you want to force. 2.2 has to go but first I need to decide whether to just fix it or mod 2.1a. Ideally, it should force both bits, but I don't see a way yet. <Dave> (SPOILER) It happens Mark, I did exactly the same thing with LOT16.1, which is why it currently shows 3/3 solved instead of, correctly, 2/2. I'm quite surprised it is so low but these 'Grab the Dalek'-esque levls do seem to cause a bit a trouble. So, as you requested, I have modded Rook's Tour to 9x9, maximal being, as you know now that you are in the Doughnut Club, 472 (or 474 steps in the implementation. Upload coming shortly. I have not been able to find any solution online, so this one will have to be solved properly. To be fair, it's actually not that hard if you approach it right. This is a good thing because any attempt at a brute force solution would take until next Easter! Also put blue back to red, I think it is safe this time. Not looked at Improv since your comments, will be in touch ... <mark> I've rated my own level by accident(Improv 2.1a)so I reset the score to 5 5 5 I will average it out after it is solved. I was scoring the one below which i had not scored straight away as i could not decide. I got very lucky on it and did not know to put. <mark> (SPOILER) Dave when i got up this morning i awoke to a few levels and improv 2.2. Last night i had already made a better version of 2.1 but left it as i've deleted enough levels lately. When i saw your 2.2 and it was similar looking to what i'd already made i deleted hoping it was not a spoiler for yours. Spent about an hour trying to mod your level then i found a flaw (check speedrun) easy fix i guess. Anyhow i've reposted 2.1 with the different ending version 2.1a. Sorry all for messing about but i do like this level,and i can still see harder things to come. |

<mark> (SPOILER) Added speedrun: 461 moves (old: 467). Had to lower scoring check this. |

<Jim> (SPOILER) Finally got this. |

<mark> (SPOILER) I thought improv was too good to give up on so i've had another go. I see that you have been very busy with your own level Dave so i've tried again. Your new level is to me even though solved is very hard to see how it works.Iv'e not rated yet as i knew how to do it but 9 or 10 for style and effort. Discovered another flaw in escape,and that is if someone delete's a level your bookmarks get lost. I had a short go on rooks before i went out and managed 327,just needed fine adjusting. I was desperate to see Jim's lucky find but i was a little bit merry and my brain won't work after a couple of beers,so i had to wait till today and start all over again. My solution not like yours at all but there are probably many. Anyhow after talking to you last time i managed to get all 15 books on pdf for free. Without you saying what the level was about in title i might not have twigged. As for what is next could you strech it to a 9 x 9 i don't know how that is done or if there are any answers available. All in all another great level but as easy as knoting doughnuts together. Cheers have fun. |

<N7DOT> A nice twist on the twist :) |

<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. |

<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. |

<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) <N7DOT> (SPOILER) Added speedrun: 112 moves (old: 402). quite simple. I really like little levels. |
|
|
<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. |
 |
<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. <N7DOT> (SPOILER) Dave, It's possible to measure direction reversals with one dalek for horizontal and vertical each, but it takes up a fair amount of space (a decision tree using teleports to connect the nodes) I won't upload my prototype so as to avoid spoiling the style points. <Dave> (SPOILER) N7, been thinking about RetCon. I long had in mind a similar idea where the space you've just left would flip if you changed direction. RetCon inspired me to get the mechanism working because it could be used for an implementation of something else. So far it works if you change from vertical to horizontal and vice versa but doesn't yet detect back-tracking. Just have to rethink 'slightly' to incorparate this too with the 15 bot limit, I will get there, very close. |

<Dave> (SPOILER) Added speedrun: 191 moves (old: 220). Not tidied up. |
