Some notes about April Contest 2024

Please 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 9 day 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.

Hello! I think there's an error in the example of puzzle 12. Specifically, the row maximum is wrong.

Thanks for the answers... however, I haven't checked, but I thought it might be possible to form a polygon (possibly concave, which I suppose is permitted) by using the S clue twice and the NE clue once, for example, if the clues for a row are S and NE. If this were indeed possible, would it be allowed?

The numeric values of the letters are the same for both puzzles.

Concave polygon is allowed. It is also allowed to use a triangle (I received this question by mail). You can use the S twice and also NE if these clues are in the same row.

For the third optimizer (counting names), the words have to form a single connected component, isn't it? The rules don't mention it explicitly.

You need to get a single connect crossword in which each word intersects with at least one other. That's right.

For the second optimizer, Easy as Opti; do circles between the two grids have to conform to both grids, even if it is left empty? i.e. is a row allowed to have something like (1) --1234 ( ) 1234-- (3) where the (x) represents a circled cell? Or should something like this always hold: --abcX (y) --dXef where the relative of X is fixed even if there is no digit in circle y? I hope my question makes sense. So if both grids have to conform (the second case), a solver can use this information in the way we could use it in puzzle 6 Easy as First and Second in the sense that if an empty circle is deducted to contain digit X if it was not empty, then the other grid should also conform to that digit X being in the first or second position, right?

Cheers :)

The same as in puzzle 6. In the circle between the grids, the digit is common to both grids. If the circle between the grids is empty, you can find a digit from one grid and use it for the second.

Thanks for the answer to problem 10 (By compass). And for problem 12 (Counting names), if we can choose the value of a letter in certain cases (D which can be 10 or 19, for example) I suppose that the choice made for a certain letter in a certain place must be the same depending on whether we consider the letter horizontally or vertically, right?

Ah, I didn't understand we were taking those rules from puzzle 6. Good question Leonardo.
To clarify, is this statement correct Riad?:
"There must be a unique solution, which has a digit in every circle and both square grids filled according to the rules."

It is not necessary for each circle to have given digits. You need to create a puzzle with a unique solution within the rules of puzzle 6.

The translator gives a sentence that I cannot understand.
When you solved puzzle 6 letters appeared in the common circles that were correct for both grids. The same should be true here. When checking, I will write the digits only in the circles common to both grids. These digits should work for both grids.
To achieve a unique solution you can additionally enter numbers in the squares.

For the answer format for optimization problems, what exactly is meant by "Type one answer key per line"? Compared to the 'Answer format' examples in the booklet, you have to go to the line after each comma, right?

You need to enter a word and cross it with at least one other word, so as not to break the rules.

Hello Riad,
I gave my answer for problem 12 (Counting names) before your answer saying it must be a single connect crossword. My answer has three non connected groups and in each group each word intersects at least one other word. Could you confirm that it is not a valid answer ?
Another question : If in a row or a column all the cells are blackened, this row or column has the score 0 in the corresponding oval. Is this right ?

Hello Christian,
You've got three crosswords, which is unacceptable.
In an empty row or column the score is 0, this is right.

Hello,
No news since the end of the competition; what's going on? In any case, like every year, I really enjoyed it!
My only regret is that I ran out of time to come up with a proper solution to problem 10 - By Compass ...

For those that are new to Riad's contest, the next step is that a PDF containing all the optimiser solutions will be shared, so the community can check they're valid. I imagine the By Compass submissions might be very slow to produce.
Also the first 9 puzzles will be scored normally by LMI, there is just some test data on that page for now.

Apologies for the delay. I have lost some of the software I use for creating the images. You are right that generating images for By Compass was indeed difficult. I have just produced the the submission entries as-is. It is going to be lot of work for Riad to cross-check.

Oops I posted a few times as the submission button seemed not to work but probably just slow internet.

I spent some time hand-drawing lines on the By Compass grids.
Quite interesting to see the many approaches.
I can't post it here, so will email to Deb.

[edit: haha Leonardo, I was also failing to submit my posts (I thought) because it wasn't letting me attach a file. A "Delete Post" option would be nice.]

Thanks for the great contest! The same wishes as L00ping007's. I solved puzzle 8 correctly, just soft click typing '-' after # LIANE----L-Q-M-#HUDAK-O-JIAQI instead of LIANE----L-Q-M-#-HUDAK-O-JIAQI.

Riad, agree with your opinion. Enough time is given to check everything before sending answers. However, why Christian got 14 points for puzzle 12? He mistook too - in the word "Lionel" he submitted digit 0 instead of "o" letter.

I've already congratulated Riad - as I do every year - on the quality of his problems and the event he puts on for us every year, which I personally wouldn't miss for the world (my son better not be getting married that week, or I'll skip the ceremony!).
I must also warmly congratulate kiwijam, who did an almost faultless job (a great performance), even though the optimization problems seemed to me to be of a very high level.
Finally, I'd like to confirm that in my opinion you need to be fairly strict about entering answers correctly and respecting the answer format, as long as it's not deemed ambiguous. We all know that this can be discriminating (I've had to pay the price), which is why it's important to keep a close eye on things.

There was an error in your solution in lines 19-21. Instead of W there should be E. I counted lines 19 and 20, but line 21 gives two polygons with a common vertex. Nevertheless, your result was slightly better than Carlos's. I gave you 2 points.

I assume the 0 points on an optimiser means that the submission was invalid. Could you send me the multiple solutions you found for my Easy as Opti?

Menderbug, I think that the right grid of your puzzle Easy as Opti has at least these two solutions:

_3124_
_2_134
314_2_
4__312
243__1
1_24_3

_3124_
_2_134
314_2_
4_3_12
24_3_1
1_24_3

Oh, you're right. Bummer, I moved a 2-clue from C4 in the second grid to C6 in the first for aesthetic reasons because I thought they were equivalent. Must've overlooked something when re-solving.

Carlos, thanks for the two solutions given. There is also a 3rd solution:
_2134_
_4_132
413_2_
23__14
3_42_1
1_24_3.
Unfortunately, in such cases, points are not allowed.

Thanks a lot for this annual contest, Riad, and specifically for this edition. The puzzles were amazing to solve (I think I spent most of the time on the Kakuro with stars), and I found the first two optimizers very fun to investigate.
Huge congrats for kiwijam, you were so close to have the best scores on all the optimizers! You really deserve your first place.
See you next year :)
