Posts: 67 ![]() ![]() ![]() Country : France | Puzlifouk posted @ 2014-04-08 11:22 PM Small question about Battleships: When you say "Maximum length of horizontal / vertical line segments", do you mean "CONSECUTIVE horizontal / vertical line segments"? Otherwise, in the example, the top right corner '2' is actually 2 1/2 long. |

For example, can the 2 on the last row have a segment of his turn crossing the quadrant border ? Does crossing the border cuts the length of a segment ? For example, with the 1 near the median horizontal border, could it cross this border and still count as one segment ? (as there is only one segment IN the quadrant) Nice puzzles anyway ! Yes, a segment of turns can leave the quadrant. In the example I specifically gave one such angle (in cell with "?"). Similar question for Battleships With Line: can a row or column have a longer segment which is partially outside the quadrant, if the portion within the quadrant is below the given maximal length? |

That is the bold diagonals of rectangle/sides of triangles. There are 6 small Trid puzzles, each has bold borders that are 7 circles long. Numbers can NOT be repeated along those 7-circle borders, or any other diagonal within the same small triangle. (it's the same idea as the Sudoku On Cube puzzle, there are 6 little puzzles with individual solutions, but they have identical digits along their common borders) |

Posts: 7 Country : Turkey | sduran posted @ 2014-04-10 1:02 AM 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) |

Could you explain pls. 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. |

Posts: 30 ![]() 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 ? |

Posts: 67 ![]() ![]() ![]() Country : France | Puzlifouk posted @ 2014-04-13 3:05 PM 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? |

Posts: 241 ![]() ![]() ![]() ![]() Country : Indonesia | chaotic_iak posted @ 2014-04-13 4:15 PM 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! |

Posts: 10 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... |

![]() Posts: 172 ![]() ![]() ![]() ![]() Country : ITALY | forcolin posted @ 2014-04-13 7:20 PM 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.
