according to diayajilin rules;
1-digit in a cell shows total number of black cells on its both diagonals
2-or shows total number of black cells on its any diagonals
for example;
digit 2 in a cell and there is 2 black cells on any of its diagonal and there is one black cell on its other diagonal. that is satisfied the rule?
In Diayajilin, if there is a digit "2" in a cell then this is the total of all black cells in both diagonals, added together.
i.e.
there is 1 black in NW-SE diagonal and 1 black in NE-SW diagonal
OR
there is 2 blacks in NW-SE diagonal and 0 blacks in NE-SW diagonal
OR
there is 0 blacks in NW-SE diagonal and 2 blacks in NE-SW diagonal
(but you can NOT have 2 blacks in NW-SE diagonal and 1 black in NE-SW diagonal )

Country : India | In my line if there is a no 2 is it necessary to have the length of lines equal to 2 on both sides or on side is enough. |

Country : France | Hi.
For 'Roman OX', I thought it was possible to use 'X' AND 'O' inside the grid, but the submission page specifies to use only 'X' and '-' ? |

It means that the shapes must cover grid cells exactly. e.g. You cannot place the 1x1 shape to cover half of one grid cell and half of another grid cell. |

Country : France | Grizix posted @ 2014-04-11 4:27 AM Another question, about Battleships with Line :
Does the maximum line length have to exist or is it just a maximum ?
In other words, for a row with a 2, do we need to have at least one line of length 2 or only 1 length lines is ok ? |

It is needed to have such a lenght. |

Country : France | Hello,
I really enjoyed this contest, with dense and varied problems. As a beginner, I always lack of time to look for problems in the usual competitions. This time, I only missed a little time to improve my optimizations ...
By the way, when can we expect to have the final results? |

We still are working on the optimizers (to check correctness of submission ). Riad is going to solve all of them soon.

Country : Indonesia | I like how there are essentially only six distinct submissions among those in Roman OX with score less than 200.
The 26x13 was amazing. I tried something similar but couldn't get 6 strands to run zigzagging like that because I ran out of minoes. But I tried it on 26x12; I should have tried 26x13 indeed. My first submission was a 26x8 with a T-tetromino at D1-E1-F1-E2, a monomino at A26, and a L-trimino at G26-H25-H26; something like the 26x8 on the booklet but with less minoes used. And obviously it can be extended at will, so a good thing there's that 26x26 limitation, too. (My submission is different, improved from the above.)
Meanwhile, time to guess the author! |

Country : Germany | Semax posted @ 2014-04-13 6:28 PM Mine is the second one, 13x23. I could not place the last piece to make the rectangle longer, but even if I could have, the 13x26 would still be so much better. I just didn't think of putting the pieces directly at the left border...

Country : ITALY | and I am the third with 25*11. did try the 6 loops but could not figure it out.
Sebastian was very good. The top solution is amazing, the idea of leaving out the trimino to respect the parity is fantastic.
At first glance it seems to me that the first two solutions of the arrows are wrong as they do not respect the rule that white cells cannot share an edge. Which may reshuffle substantially the leaderboard for the top positions......
As usual, Riad has pulled out from his hat a set of puzzles of fantastic quality. The astronomer is in my opinion the best puzzle. of the optimizers I like the Pentomino, it has so many possible strategies for getting the extra step. Thanks to Riad and the other organizers.

We added the restriction of 26X26 almost at the end because we thought there will be confusion over answer keys entering. But it looks like there would have been much confusion without it.

Yes, those are invalid grids. I missed that rule while making the pdf. |

my guess is Tomoaki
The limit at 26 has also another function, to make illegal the solution (infinity, 2 ) which came to my mind immediately. Pity. |

Country : France | auroux posted @ 2014-04-13 9:43 PM For Roman OX, the second listed solution with 160 (middle of top row on first page) is incorrectly formatted, with an extra ";-" in the horizontal clues and a missing vertical clue. I assume this is because the contestant separated the two halves with a ";" instead of a "," and in fact submitted the same solution as the 3rd listed one (immediately to the right).
(As for myself, I feel stupid for finding the solution scored at 180 and managing to convince myself that none of the clues could be removed, when the two distinct solutions scoring 160 are in fact obtained precisely by doing so. Duh). |

I'd have suggested an infinity x 8 to score better than an infinity x 2. :P |

Thank you Deb for your support!
With your pdf-files check solutions has become fast. Previously, I had to draw dozens of puzzles, and then check. |

I made a stupid error while submitting my entry for #5, but I still did better than I usually do on the speed tests. Plus I usually skip optimizers but thought I'd at least try this time! |
