Location: New Zealand | Anurag, please show respect to Riad, I'm much enjoying the effort he has done for this competition.
I think the Magic Tapa expression is clear and makes sense as it is (range minus minimum). As he says, you can maximize whatever you like but the final scores will be based on the official expression.
And yes, a score of -1 would be better than a score of 0 if you can achieve that. If there are other negative scores then the most negative score would be the best. |

Location: France | I do not know what "score" you are talking about when you say "And yes, a score of -1 would be better than a score of 0 if you can achieve that. If there are other negative scores then the most negative score would be the best."
If the score is the final score to maximize (that is | R-r | -r + | C-c | -c), then personally I have never seen that -1> 0 nor -10 > -5 !?! ... But you are free: as you say the expression is clear, everybody will interpret as he wants. |

Location: India | That's Correct and clears the doubt, at least for some.
The whole purpose of asking questions is to be able to complete the set and I am sure puzzle solving is not an objectionable activity. For any unrelated suggestions/objections, I believe personal emails are a better medium. |

Ships: As it is not mentioned on the file, I assume the fragments are pulled out straight without rotation and can be put back the same way as they are. Also, the column clues consider all 10 cells and not just the 5-cell strip.
Probably everyone might have understood the puzzle description, but since I didn't and need some clarification;
A)Is the red clues in the 5x10 fragments intended to be solved as 5x10 battleship clues, or is the red clues the equivalent of 10x10 original battleship clues?
B)Is it okay for ships to be 'fragmented' in the 5x10 clues? |

Location: France | Very sorry all, the expression has to be minimized! So everything is clear and ok, I will not comment this point any more. |

Location: Russia | In puzzle 11, I will remove the brackets, if it is principled. Minimize the expression R – 2r + C – 2c. James rightly noted that the minimum can be negative.
In puzzle 7, the red clues extend to 10 cells.

Location: United States | I have a question about "at the levers."
If two digits are on one side of the balance, is each one multiplied by its distance from the balance? So if there are two digits next to each other on the pivot, with the closest one unit away from the pivot, would the total for that side be thw closer digit plus twice the outer digit? |

Location: United States | It looks like the example for dice masyu has multiple solutions, can you confirm if this is a mistake or if I am misunderstanding a rule?

Location: New Zealand | @randomperson1729: Exactly right.
@ghirsch: The Dice Masyu example has multiple solutions, but the big puzzle has only one solution.
@deu: No, the 10x5 rectangles can not be rotated or reflected. |

Can two grids use the same ship type?
8. Dice Masyu
What happens when you place a dice on top of an existing circle? Does the position of this existing circle have to match the position of a circle on the dice? |

Location: France | A small question again, about "Fragments of seas" : is there 1 fragment from each grid, or is it possible that 2 fragments come from the same grid, and no fragment come from another grid? |

Location: France | I'd like some clarification about Dice Masyu.
What happens when you place a dice on top of an existing circle? Must the position of the existing circle match the position of a circle on the dice?
Do all existing circles in the grid belong to a dice?
Edit: Sorry for the double post, I thought I made a mistake and didn't correctly submit the first one

One type in each grid. The answer to your question is "NO." |

Location: ITALY | 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

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

Location: United States | 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 |

Location: New Zealand | 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. |

Location: France | 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 ? |

Location: India | 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.

Location: United States | 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? |
