WPC 2013 - IB - Questions and Answers

Postby Gyorgy ISTVAN » Thu Oct 03, 2013 6:02 am

Dear puzzle-friends,

the full Instruction Booklet for the WPC 2013 will be available within a day on the official WSC-WPC site.
I started this topic in order to have a place where you can ask your questions (or simple write your opinion) and get answers in advance, so the Q&A session can be a short one in Beijing.
Please note, that there will be a different topic for the WSC IB.

Best regards,
Gyorgy Istvan

Hi, I have a question about Part 3, puzzle 7 - Digital honey

Does the rule about all different neighbors (of a digit) apply to a black field?

Thanks

No, the rule that "neighbours of a digit are different from each other" only applies to cells with digits. Neighbours of a black cell are not required to be all different.

Question on the Finals Format (given a wide range of flipchart experiences in past years):

Will solvers be required to use marker or will colored highlighter or even pencil be allowed? In the event only dark marker is allowed, will there be a second copy of the puzzle available to a solver in case, say, their Radar becomes quite obscured? Is there any contingency planned for a puzzle that neither solver can finish within a particular time (there was a WSC example last year that took over 15 minutes and was quite a mess for both solvers)?

Thomas - given that your questions are relevant for both WSC and WPC, I need to sync up with WSC organisers before committing to a response. Please allow some time for us to do so. Thanks.

Received a question offline on the Radar puzzle, featuring in round 2 and the play-offs: "Are the rectangles allowed to have dimensions of 1xN?"

The answer - no, 1xN shaped rectangles are not allowed. Both dimensions of every rectangle have to be at least 2.

Regarding the details of Finals to be held on flipcharts, I can now confirm that the following clarifications apply for both WPC and WSC:

1. Solvers will be given two markers (one black, one blue) and will be asked not to use any other tools for writing. According to local organisers, the rationale includes that the type of paper that these puzzles will be printed on does not work well with pencils. Spare markers will be available in case they run out of ink.

2. There will be exactly two copies available of each of the puzzles in the Final. In case their puzzle becomes too obscured, solvers have the option to ask for a clean sheet (once per puzzle) at any point of time during their solve (but not within the one minute of verification time).

3. The solving times of each of the puzzles in the Final will measured by a clock that's clearly visible in the room by the solvers, judges and the audience. In case neither solvers finish a puzzle within 15 minutes, the round is halted and declared a draw, whereby neither solver gets any points (but if a solver declares "ready" just seconds before the 15 minutes elapse and their solution is correct, they will get the win for the round, even if the verification of their puzzles does not finish before the 15 minutes are up).

If such a draw occurs, then it is possible that neither finalists reach 3 points from the 5 rounds (e.g. the standing is 2-2 with one uncounted draw). In an event like that, as a tiebreak, they will start solving a 6th puzzle (or possibly even a 7th one, in case of at least two draws, and so on). The puzzles in a tiebreak will be the puzzles that have been eliminated by the finalists. The puzzles that were eliminated last will be used first. E.g. the 6th puzzle should be the one that was eliminated with the 5th choice. Note that this way the sequence of alternated favouring of the finalists that is implied from their alternate choice/elimination of puzzles does not break, because in the 6th round they are solving a puzzle that the 1st placed solver had chosen to eliminate, therefore this is designed to be in favour of the 2nd placed solver, just as all the other even rounds, while the odd rounds are designed to be in favour of the 1st placed solver.

The Final is designed with 10 puzzles, with the Finalists choosing 5 and the other 5 available for tiebreaks. If 10 rounds were not enough to decide the winner, the title is decided by the results of the two days of main competition, according to the rules in the Instruction Booklet. If even that doesn't help, we will toss a coin, seriously. (We are not talking about plausible events here - we thoroughly tested the Final puzzles and we believe they are all humanly solvable and well within 15 minutes, especially by people capable of getting there!)

Hope that helps - please let us know any further questions.

Two more minor clarifications:

1. Round 07, puzzle 12, "Odd-Even Tapa" - none of the digits concealed by an "E" can be zero.
2. Round 13, puzzle 3, the name of the puzzle is Trinaire, without the extra "a" in the middle.
