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.

Updated booklet uploaded. Some calculations were wrong in puzzle 12.

Lots of luck to all players, and thanks to Riad for organizing this tournement, which will certainlay be fascinating as usual.

Is there something wrong with the Optimizers column on the potential score page? I have submitted 2, but it says 3. For Christian, it says 4...

In task 7 are there two different sets of numbers for Battleship and Pentamino or are the numbers the same for letters in both problems?

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?
