Puzzle 10: I have a question about the sentence "The white cells must form streets. The white area of the streets cannot contain fragments of 2x2 cells."
Is this the rule of a Town puzzle or the restriction on answers (in this case, a Town puzzle is the same as a so-called Clouds puzzle)?
For example, the mini-example without "2" is valid or invalid?
Without the digit 2, the example does not have a unique solution.
Oh... I maybe misunderstand the rules of "Town puzzle"...
My former interpretation is as follows:
Make a Town puzzle with a unique solution in the 12x10 grid.
"Town puzzle" rules:
Place some dark rectangles, that are at least two cells wide and two cells high.
They can not touch each other, not even diagonally.
The numbers outside the grid show the number of dark cells in the corresponding row or column.
The white cells must form streets - the any stretches with a width of one cell and length at least 2.
The white area cannot contain fragments of 2x2 cells.
(<- the rules of "Clouds" + street rule )
Conditions for optimization:
Maximize N, the number of streets.
If two solutions have the same N, then the solution with the smaller sum of the given numbers is considered better.
However I read this reply and guess that the following interpretation is true:
Make a Town puzzle with a unique solution in the 12x10 grid.
"Town puzzle" rules
Place some dark rectangles, that are at least two cells wide and two cells high.
They can not touch each other, not even diagonally.
The numbers outside the grid show the number of dark cells in the corresponding row or column.
(<- exactly "Clouds" rules )
Restriction on the answer grid: (= NOT "Town puzzle" RULE!!! ONLY FOR OPTIMIZATION!!! )
The white cells must form streets - the any stretches with a width of one cell and length at least 2.
The white area cannot contain fragments of 2x2 cells.
Conditions of the optimization:
Maximize N, the number of streets.
If two solutions have the same N, then the solution with the smaller sum of the given numbers is considered better.
Which interpretation is correct? Or still misunderstanding? Please clarify!
I now understand where the questions came from. In the September Contest 2010, I published the Town puzzle. When solving this puzzle, we used the condition that the white area does not have 2x2 fragments. I repeated the name of the puzzle in 2020, but without looking back at the previous work. This point probably confused the solvers. In this April Contest, I suggest using the second option that you have described.
I see how it is. OK, now I consider this optimization by using the latter option. Thank you for your reply! |

Otherwise it would have no solutions, if I'm looking correctly. But still, even if they don't all have to be filled in, can at least some of them be filled in? |

Country : Indonesia | athin posted @ 2020-04-12 4:56 AM Oh well, I already had a nice construction for the first interpretation, now I have to update it (or maybe scrapped it).. Hope this kind of misunderstanding doesn't come in later contests.
To clarify again, the solution of the town puzzle may have 2x2 cells. But if it happens, then it will get absolute 0 points. Is this correct? |

Country : India | anurag posted @ 2020-04-12 12:49 PM Yes, 2x2 areas are fine, but give no points. 1xN streets will earn you points. I suppose the admin has vowed not to reply to any of the questions, but to take down posts.

Puzzle 11:
If for example I only use 5 rows x 10 columns table, should I just put only the contents in row 1 to 5? And should I just put 10 characters in one row?
Sorry before, but this question hasn't replied yet. I'm afraid it's missed because of the puzzle 10 discussion. Thanks |

1. In example, is there reason that [0,0] should be used?
2. Should "ALL" dominoes are placed? If so, why is there no [1,1]?

2. Should "ALL" dominoes are placed? If so, why is there no [1,1]?
1. It is simply that examples are illustrative and some authors usually make examples without putting much effort into it. There is no specific reason why [0,0] has to be there. It has multiple solutions. However, I would think it is advisable to have the example illustrate all rules.
2. Most likely not. I believe all are to be used. But I could not make progress beyond the right-most column, so I can't tell for sure.

Or is that not required? |

Country : Indonesia | athin posted @ 2020-04-13 4:53 PM I'll try to help answering some queries:
Puzzle 5:
- You should put ALL cards. That's why [0,0] are in the example. I have solved this puzzle so the rules should be good.
Puzzle 11:
- All cards are not required to be connected. And surely, if the solution has multiple occurences of a card, but only one that does not contradict with the rule (i.e. not sharing an edge), it is acceptable. Because.. some cards are basically subset of another card.
- For the answer key, we don't need to specify the border and number because the instance of the puzzle is just a grid with some diamonds in some cells. |

There is some confusion about the answer key, as I mentioned earlier. I would like this to be cleared. |

There's an obvious typo. In the lower right corner should be 1-1. Please note that I do everything manually and do not access programs. I'll fix the example and update the file. |

I managed to solve it considering that every external border is a wall (like in the example ).

1. Puzzle 10 Town. What if I accidentally sum up the given digits wrong? But the rest of the puzzle is correct.
2. Puzzle 11 Diamonds. What if I count the amount of diamonds wrong, but my solution is valid and is described correctly with (WWRWRW...)
3. Puzzle 12 Opti-battle with losses. What if I calculate the equation wrong although the puzzle describe is valid.
4. Puzzle 12 Opti-battle with losses. What if I miss some of the possible solutions. Let's say I get 3 solutions, but I actually have 6. (Therefore my equation also gets wrong). But the puzzle created is valid.
5. Puzzle 11 Diamonds. Can 2 cards touch each other by corners? |

1-4. All calculations are double-checked, don't worry.

As always, there will be no problem with that. It is only a little overhead for the author to report back claimed and actual scores.
4. Puzzle 12 Opti-battle with losses. What if I miss some of the possible solutions. Let's say I get 3 solutions, but I actually have 6. (Therefore my equation also gets wrong). But the puzzle created is valid.
Score should be based on the submitted solution.
5. Puzzle 11 Diamonds. Can 2 cards touch each other by corners?
Cannot.
