Moscow Puzzle Cup 2016 Author Posts: 234 Location: Russia | chaotic_iak - 2016-04-20 2:06 PM Borderless Sextet: - Must all cells in the loop region be used in the loop? Is the loop's length 16? By "touching", does it mean Snake-like touching (being on adjacent cells while not being consecutive cells in the loop) or Masyu-like touching (using the same cell twice)? - Do the diagonal clues for packing count multiple cells of the same region only once or as many times as the cells? (That is, do they add up regions' numbers or cells'?) 1. The loop region consists of 16 cells, the length of the loop 16. Everything else you determine by solving a puzzle. 2. The sum of the numbers in the yellow cells are indicated along the two diagonals. For example, if along the diagonal 6 yellow cells, that indicated the sum of the numbers in this 6 cells. | ||

Posts: 172 Location: ITALY | debmohanty - 2016-04-20 5:54 AM auroux - 2016-04-20 3:13 AM I don't think I understand the answer format for puzzle #1, or else I'm not sure I understand why my submission triggers the red message "pentomino letters, + or -" as if it were malformed. Could an organizer check whether my submission for Pentobattle is well-formed? (answer key contents are valid and of the correct length to match expected answers?) (I also happen to think that I have solved the puzzle correctly but understand that you'd rather not comment on that). Thanks in advance! Denis The red warnings are not correct for this puzzle. Will have them fixed. I had the same problem as Denis. will wait to see when it's fixed | ||

Moscow Puzzle Cup 2016 Author Posts: 234 Location: Russia | Para - 2016-04-20 5:53 PM In "In the Citadel", I assume there is only a restriction on using stairs once and not on the paths between the stairs? Yes, there is only a restriction on using stairs once. This is evident from the example in the Answer format. | ||

Posts: 172 Location: ITALY | a question about 4.BRICKS. the brick fragment which must be filled with the length of the brick will always occur at one of the ends of the brick or it can occur also in the middle? | ||

Posts: 187 Location: New Zealand | "Borderless Sextet" questions: - Is every cell of the grid in one of the 6 regions? Or can there be cells which are not used? - Packing Figures are only on white cells, Battleships only on blue cells, the other 4 regions can be white or blue. Correct? - The Battleships region must include empty cells between ships, but can other regions include empty cells also? e.g. can the Snake region be larger than 19 cells, or can the Scrabble region include cells without letters? I think in the other three regions, every cell must be part of a loop/tetromino/yellow figure? | ||

Posts: 315 Location: The Netherlands | In Opti Pentobattle, if I input the wrong K+1.5N because I didn't count the number of solutions correctly, will my solution be counted as wrong or will it count as the correct K+1.5N? | ||

Location: India | Para - 2016-04-21 10:05 AM In previous years, Riad has corrected the "optimized value", if it is wrong. It will be done similarly for Opti-Pentobattle. In Opti Pentobattle, if I input the wrong K+1.5N because I didn't count the number of solutions correctly, will my solution be counted as wrong or will it count as the correct K+1.5N? The purpose of asking optimized value is to sort the solutions quickly. | ||

Location: India | Tie-breaker for Puzzle 10 - OPTI-PENTOBATTLEAnnouncement from Riad - Tie-breaker for solutions with same value of K + 1.5NIf two solutions have same value of K + 1.5N, the solution which has smallest rectangular Pentomino area will be considered as better solution. | ||

Is that the smallest rectangle the pentomino shape could be fitted in (with max dimensions 10 by 10)? Is this purely by size (9x4=6x6)? | ||

Moscow Puzzle Cup 2016 Author Posts: 234 Location: Russia | Para - 2016-04-22 5:29 PM What does smallest rectangular Sea Area mean exactly? Is that the smallest rectangle the pentomino shape could be fitted in (with max dimensions 10 by 10)? Is this purely by size (9x4=6x6)? The best, where Pentamino area limited by the rectangle of smaller area. For example, the area bounded by the rectangle 8x10 better that by the rectangle 9x9. The length of the rectangle cannot be more than 10. | ||

Typed Logic Author Posts: 241 Location: Indonesia | So it's the area that's not covered by pentomino, the area that doesn't contain the ships? | ||

Posts: 187 Location: New Zealand | So it's the area that's not covered by pentomino, the area that doesn't contain the ships? The area not covered by pentominoes is "land". The pentominoes are the "sea". The ships are placed into the sea somewhere. So then the pentominoes contain ship cells and empty sea cells. You need to find the smallest rectangle (max 10x10) that will hold all your pentominoes. | ||

Typed Logic Author Posts: 241 Location: Indonesia | Oh, right, ships are placed on sea. I instinctively translate regions left without pieces as sea. I also misread the tiebreaker, thinking that the tiebreaker is to minimize the area of the largest rectangular region that is entirely inside the pentominoes. | ||
