I have to admit that it is a little bit frustrating that this simple question cannot be clearly answered by you, even after being repeated five times. I do not really understand why it is that difficult to just say "yes, programming is allowed" or "no, programming is not allowed".
To be clear: I have no clear opinion about whether it should be allowed or not (I haven't programmed yet and I probably won't have time for it anymore), but I dislike the fact that you ignore one specific question for a whole week while answering every other question just a few hours later. For this contest it may be too late, but please don't do this in future contests again.
Hello Christian,
If I knew the answers to all the questions, of course I would have suggested it. I don't program and participate in all tournaments without resorting to this process. Let's leave this question to the discretion of each puzzler.
1. The contest is literally called "Riad Khanmagomedov's April Contest". It is your contest. You decide the rules :- ) If someone else decides the rules, and you just run the contest, you should know who to ask
2. For the contests with an instruction booklet, it seems there is a standard wording in the rules:
Outside solving help of any kind is not permitted. This includes but is not limited to:
assistance of any kind from any other person; prepared notes, books, calculators,
computers, or tools other than items explicitly permitted.
I would assume this goes for this contest as well, and for any other contest on the site with no explicit rules. |

About the equation, the first three are not valid: "_PLUS_65821=-9403x-7" and "65821=-9403x-7" use two consecutive operators, which is not allowed (based on an answer on this thread). Maybe you will cap these solutions to the optimal one (with score 658210), since this issue was not clarified in the Puzzle Booklet and was fixed only the last day of competition.
Huge thanks for all these beautiful puzzles, some classic ones were really hard and very enjoyable to solve! |

Yes, THANK YOU RIAD for some really great puzzles. I love the format, much more satisfying than 60/90 minute frenzy with the printer
On first seeing them, I thought I would hate the optimizations, but in the end I loved them all. It turns out the only thing I really hate is Mechanical Sudoku. The number equation was the least fun of the optimization - mostly because I resolved to manual brute force,. I am happy to see that I managed "local optimums" for Record Score (best solution with symmetrical paths ), and Opti-Road (best solution with G=g (or V=v ).
As for the top three solutions for "From 0 To 9":
Since these solvers were aware of the possibility to use negation/unary minus, which was explicitly endorsed by Riad on the forum, I would think it fair to allow them the top solution utilizing it:
-65821=-9403x7

Thanks Paul,
I have completed the check and you will see the preliminary results very soon. |

Thank you Nis,
In your solution 12. Record Score there were forbidden passes, which reduced your result.
The result -65821 would be minimal, but it was necessary to strive for the maximum. |

Indeed, and indeed.
I also see that I had errors in 2 of the regular puzzles. Bummer.
It does seem like some scores are missing for puzzle 10 (including mine ) - not sure if this is also due to invalidity of the answers? Seems unlikely, since "moeve" submitted what looks like the same solution as me, modulo reflection, and scored 8 points for it
Anyway: Thank you, once again. |

I checked the table with my sheet. Some points were not saved. I'll ask Deb to add them.
P10:
Jo97 11 points,
Nizz 8,
Ausmunchkin 5,
Tiralmo 2 (Tiralmo confused the setting digits horizontally and vertically, but I counted him 2 points ).
P11:
Sugitakukun 11,
Christian 5.
Thanks! |

All the optimizers were interesting, and I think that the LMI-Road puzzle has a good new logic idea. |
