Hi all,
what about multiple submission for optimizer puzzles? There is reduction of potential score, as for usual LMI contest, or are allowed without impact on the score?
Thanks
Gabriele

Last submission will be considered. There is no penalty as there is no instant grading.

Hi there I am enjoying your contest. It is very well done. I do have a question about Dice Maysu. If you cover an existing circle with a half domino is it still 'seen'? For example, if one were to place a domino of six such that a pre-existing circle would be the middle of that six after placement --- would the middle circle be covered ? Would the circle be 'in play' along with the rest of the domino ? Or would one not be allowed to place a domino of 6 in such a location?

Thanks -E

In Dice Masyu, every given circle must match a half-domino circle.
e.g. You cannot place a 6-domino such that the centre cell of the 6 covers an existing circle.
And you cannot have an existing circle with no half-domino covering it.

I understood my mistake on Levers, and finally solved it ! So my earlier post can be trashed ...

I also just solved "Crossword with tips". Great puzzle ! I loved it
But I was surprised to find multiple distinct solutions to this puzzle (i found 5)
However, the marked diagonal is the same for these 5 solutions, so no matter.
Are you aware of these multiple solutions, or do you want me to provide them to you ?

Hey Looping,
It is interesting that you managed to find 5 solutions. If it really does have multiple solutions as you say, it is not 'ok' just because the answer key is unique. Answer keys are there only to allow for claiming that one has solved the puzzle.

I have a question about distyle.
In the rows at the edges of the board, do the gaps count as white squares, or are two black dominoes across a gap counted as part of one black grouping?

I also found 5 solutions to this puzzle. As marked diagonal is the same for all of them, I submitted that common diagonal.
(If organizers need alternative solutions, I can send them.)

Once the contest is over, I'd like someone to send me those alternate solutions, as I completely missed them during my solve.

Tapa's answer key is as taxing as solving the puzzle itself. 12,0,7,0,6,0,....format would have been far easier.

Tapa: The focus in red background next to the text input will not go. It is there eternally even after entering the answer key string. Is something wrong with that part of the page? I would be glad if the admin can confirm the answer key was received.

I can see a couple of optimizers (not mine) with single cell mistakes, presumably from entering the long answer keys.
Do we have a rule for these situations? I don't feel that 0 is fair if they put hours(?) of work in.

It is not always possible to organize a competition perfectly, I admit.
During the checking optimization answers, I took into account a few moments:
PENTOCOLOUR. Without points those answers where the same pentaminoes touched or the same black pentaminoes met twice. Taner instead of the claimed 42 points scored 40. Henna, Pierdante and Eugene's answers contained extra orange and black cells, but I figured it out.
MAGIC TAPA. Anthea missed twice: in the top row instead of (12) he indicated (3), and (23) placed in the 4th row (it was necessary in the 2nd). KuroTent placed (23) in the 8th row, not in the 9th. I counted them the claimed points. Shinichi do not score points, because in his puzzle multiple solutions.
MAXIDOMINO. Kazuya lured places 1, 3 and 4, Vladimir changed 1 and 2. I awarded them points. Anurag and Nicholas are not score points, because in their puzzles are multiple solutions.

I congratulate James, Christian and Tomoya!

In the final table, the scores for the 7th puzzle are rounded (8 instead of 7.5 and 3 instead of 2.5).

Riad, thank you for the very interesting tasks! As always, your assignments are simply unique! Sorry, I did not have enough time to show a more decent result. It's amazing that you noticed my flaw on MAXIDOMINO (replacement 1 and 2) - thanks for the reward! And it is surprising that you didn’t notice my failure to refine PENTOCOLOUR (replacement of black L and V), which would give 37 and +6 points to the final table. This is how your appetite for your attentiveness grows!) I apologize that it may have frightened someone who counted himself 74 in PENTOCOLOUR - does the orange color of pentamino are so much worse than black not to count orange?) I'm already looking forward to your new habitually unusual and interesting tasks! Thank you for the good work!

I would like to thank Riad for beautifully though contest, as usual. :-) My favourite pieces were Sumino and Dice Masyu, meanwhile, I broke twice the Crossword because I did not realize one extra possible combination at the top of the puzzle. In optimization I am still such a beginner, but we will see next time. :-) I am looking forward to it. Thanks once more.
