Puzzle 11: If the solution has multiple occurences of a card, but only one that does not share borders with other cards, is it acceptable?

Puzzle 5:
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]?

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.

What about the answer key for Diamonds? How can we specify the borders and numbers?

Yes, that should be fine.

Puzzle 11: The instructions miss one more detail: All cards must be connected.
Or is that not required?

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).

Cards may not overlap.

What happens if I miscalculate something in optimizers? Lets put here some concrete examples to make my question more clear:

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.
5. Cards can touch each other by corners.

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.



Score should be based on the submitted solution.



Cannot.

I did not see your reply before posting mine. Cards can touch? In the squares puzzle, squares cannot touch. I thought the same rule applies here. Are you sure?

It would be nice if only author answers the questions. In that way we can be sure that the answers are correct and it doesn't get messy.

Thanks Riad for the answers!

Puzzle 11:
1 ) Can the corners of the cards touch?
2 ) Can diamonds go one on top of the other?

1 ) Yes
2 ) In the example, cards 3 and 5 share a common diamond.

In puzzle 8 of the contest does the direction on the bottom, 2nd from left, end before the edge of grid intentionally, or is this an error?

Considering the "white streets may not form 2x2 area" rule in 10 is actually not part of the Town ruleset, but a requirement for the author (that we must form a unique Town puzzle, which happens to have no 2x2 white area), I'll have to ask the same for 11 too: is the rule "cards may not share borders" part of the Diamonds ruleset (if there are multiple ways to reconstruct the contours, but only one of them also has no cards sharing borders, then the solution is unique) or is it a requirement for the author (the solution in the previous case is not unique)?

Your quick retort was rude and unnecessary, if not ridiculous. On the contrary of what you think, and if you have not been following, the participants are NOT the source of mess. Instead they are the ones who are doing the admins' job.
Everyone is confused with many of the puzzles. Even after all that tedious messaging back and forth, look at the last question here - Chaoticiak has still got the rules of puzzle 10 wrong (or I got it wrong). I am also not sure yet as the 'suggested' but not confirmed second version appears to be a trivial puzzle. You can imagine how shabbily all of this was managed. The earliest queries regarding Puzzle 10, for example, came from me and they were selectively taken down for no reason!

The random change in Puzzle 11 is unacceptable just 2 days shy of the deadline. It would be unfair as I had not considered corner touch until now.

I do not understand how that answers the question. If language is a problem, the admin should own the responsibility of a mediator.

I think I understand your third version. Is it different from both versions described here previously? I think it is. One can take the liberty to innovate, given that the instructions were woefully inadequate.

Puzzle 8: Hex maze
Answer format is total number of obtuse angles of the path. Do I have to count (the number of obtuse angles) both sides of each turn of the path?

An obtuse angle measures strictly between (and not including) 90 and 180 degrees, so even if you did count both sides, you should arrive at the same answer.
