Country : India | Some notes about April Contest 2022Please note this contest will have a slightly different format than regular LMI tests.
Key differences from regular LMI tests:
1. There is no IB (i.e. no Instructions Booklet). If you have any questions about any puzzle, please ask here in the forum.
2. The PB (Puzzle Booklet) does not have any password.
3. You can download the pdf and start solving. Login at the contest page and click on "Start test" to start submitting.
4. There is no time limit other than the 1 week duration. You can submit until the contest ends.
5. There will be some optimizer puzzles. Other puzzles will be very hard (compared to regular LMI tests)
6. Same scores will have same rank (i.e. early submissions do not count towards rank)
Other important points:
7. There shall be no instant grading in this test.
8. There shall be no online solving interface (like penpa) provided for this test.
9. The score page shall be made available later.
10. There shall be 10 pages in the Puzzle Booklet.
11. Participants can submit answers any number of times. The last submission shall be considered for scoring.
12. There shall be no separate notification on submitting answers.

No, in this case, the ball is re-addressed to the player who cannot be used. |

Country : Germany | CJK posted @ 2022-04-16 3:41 AM For Record Score, does the goal shot also count as part of the path? Especially, if one team has a player next to the opposite goalkeeper, can the same order of players count twice (since this player can kick the ball directly or diagonally into the goal) or is this counted as the same path? |

Country : New Zealand | kiwijam posted @ 2022-04-16 10:24 AM I have some clarifications for the optimizers. Please correct me if I'm wrong.
10. Opti-Road:
There is an error with the example. The column digits should be 22212, not 21212.
Also there is an error with the example answer key: the score for the example is 8, not 9.
11. From 0 to 9:
Without parentheses, we will always do multiplication and division (x and / ) before addition and subtraction (_PLUS_ and - ). Also, dividing by 0 is not allowed.
12. Record Score:
Total score is number of white paths plus number of black paths. The example is simple so I attach another one.
In this, White has 1 path, 1235674 (this is from the previous question from Christian - I think it is not important which direction #4 scores? ).
And Black has 2x2=4 paths, 1234567, 1234576, 1324567, 1324576. It is not possible to go from #4 to #6 directly.
And so the total score for this example is 5.

11. Yes.
12. Yes.

Hi Stefano,
1. It is not forbidden, but the fragments do not overlap each other.
2. Yes. |

If I am not mistaken, CJK's question doesn't have an answer yet. It would be convenient to know if we have to work only with paper/pencil for the optimization problems or not, in order to be rated with the same criteria.

Hello Riad,
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. |

How do you approach to final solution from your initial guess/solution?2. How do you become aware of that you have reached to the optimum solution? That depends on the specific optimizer, but basically I first try to build a solution, any solution.

After a few attempts, usually, one has a sense of whether one has produced something good (possibly close to optimal ) or if it feels that there are some guiding principles that aren't understood yet. And of course, often, there are BIG surprises when discovering what other people have managed to do with the same optimizer problem. I don't want to comment too much while the contest is going on, plus I'd risk making a fool of myself if I made hasty pronouncements and it turns out my solutions are really really far from the optimal ones, but after initial skepticism I became quite fond of this year's optimizers. I think they are extremely well designed, in the sense that one can profitably approach them by hand and get a sense of how they work; and, if I dare say so, I don't think computer brute force search would be particularly more helpful on these than careful thinking and formulating intuition. |

Two white players cannot pass to each other if there is a black player on the line between them. And two black players cannot be connected by a straight line if there is a white player between them. I hope I am not one of those with errors. I have a solution that works well on paper, and proofread what I input into the submission box, but still am not confident that I encoded my solution correctly. Forming the answer key was the least enjoyable aspect of working on this optimizer, perhaps because I feel really bad at encoding/decoding grid coordinates when letters are used in both directions.

But when I returned to the answer page after submitting it looked normal, so I think they can be ignored... The contest end time was set incorrectly, hence the confusing error message. It was sorted few hours back.
If anyone else is seeing message like "contest is over", request to refresh the submission page. |

Thank you @auroux for the comment. Actually this is how I solve these problems: firstly, finding an initial solution/taking a guess, then improving the solution till I'm satisfied. But, this time I thought maybe by any chance there is another way of doing this; like in other puzzles, they have very good and well designed pathway to reach to the one and only solution and if you follow the logical pathway you know that every step you take you are correct and will reach to the only solution. For optimizer puzzles, in the same way I can reach to a solution but most of the times I can't be sure whether it is optimal. I can only know that after checking top solutions once the contest is over. Again, thank you for your opinion, this clears my dilemma. |

Country : India | About the Record Score Example posted by Kiwijam, is that a valid solution? Because, the instruction says that own goal is not allowed. Here, BLACK numbered 6 player is on the row (row R) from where he can shoot the ball to his own goal. Similarly for WHITE numbered 3 player, he can shoot the ball diagonally to his own goal. Or, is it just calculation of own goal is not allowed? |

I need clarifications about the second optimizer puzzle:
- Is it allowed for a side of an equality to begin with a _PLUS_ or - sign? Such as 8_PLUS_3 = _PLUS_11 or 5 - 6 = -1?
- Can two arithmetic signs be consecutive, like in 8x-3 = 6x-4? Here, the cross symbol 'x' and the minus sign '-' are next to each other. Is it a valid equation?

Hello Christian,

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. |

Country : France | Carlos posted @ 2022-04-23 11:08 AM Woah it's nice to see all the puzzlers' solutions for the optimizers!
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

Woah it's nice to see all the puzzlers' solutions for the optimizers!
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!
Thanks Paul,
I have completed the check and you will see the preliminary results very soon. |

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
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. |

Hello Christian,
It is noted on my sheet that you have 5 points. Sorry, we'll add it now. |

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. |
