Does it mean that length and width both should be > 1, or the area should be > 1? The length and width both should be > 1. |

Is it on the belt, in the enclosed space, or the union of the above? No stars on the belt. |

The total of mines is given. It's the only place the 4th mine can go. |

Posts: 35 ![]() Country : United States | FoxFireX posted @ 2013-04-11 6:24 AM Couple of questions on the optimizers. For Domino Castle, the answer page notes that "some rows may not be used". Does that mean that if we build the castle into, say, a 12x12 grid, the empty rows/columns don't count against us as the minimum row/column value? For Tetrasudoku, it's not explicitly stated, but I assume I know the answer: Must the sudoku be solvable at all? That is, is it acceptable to create a puzzle which has no solution, making the value of K=0? (I can't imagine that's okay, but figured I'd bring up the possibility anyway.) |

If you count the length of the line from dot to dot, then that length must go up or down by one from one segment to another as you travel the loop. In the example, if we start with the segment in the upper left of the grid and go clockwise, we start with a segment that's 2 units long. The next is 3 units long, then 2, 1, 2, 1, 2, 1, 2, 3, 2, 3, 2, 3, 4, 3, and back to the original 2 unit segment. |

Posts: 668 ![]() ![]() ![]() ![]() ![]() Country : India | swaroop2011 posted @ 2013-04-11 3:04 PM Just to confirm, In Domino Castle we have to use all dominoes i.e 1-1,1-2...1-7. ......7-7 so in all "49" dominoes right ? or is it 1-1,1-2...1-7 then 2-2,2-3..2-7, 3-3.. so in that way 28 dominoes ??

You have 28 dominoes. Using all dominoes build a castle. Castle is connected freeform figure. |

You have a set of 28 different dominoes to use, once each... You have to follow the given rules, but if the rules don't restrict something, then you can do it. |

![]() ![]() ![]() ![]() ![]() Country : India | Administrator posted @ 2013-04-12 5:53 PM About Domino Castle : Please note that no domino can be used twice. (So each domino has to be used exactly once.) We can see that in some submissions, a single domino (e.g. 3,4) is used twice. This is not allowed. Those submissions are invalid, and will not be considered. |

![]() ![]() ![]() ![]() ![]() Country : India | Administrator posted @ 2013-04-12 6:01 PM Yet another note about Domino Castle : The task is to minimize the expresses (R-r)^2+(C-c)^2 Not to maximize it. We see a case, where the player has (probably) tried to maximize it. |
