Overall it's a fairly nice test, I enjoyed it. It's a bit unfortunate that there was no JOC example in the test case. For submitting, after ten puzzles without popup I was pretty sure I had done something very very bad when there was a popup after the eleventh puzzle. I was confused and read the popup twice very carefully, just to more than double my solving time. And another little thing that I don't understand: Why is there an automatic submission after 5 minutes? There are so many situations where this is bad. Can you tell me one situation where this is good? | ||||||||||||||||||

Posts: 739 ![]() ![]() ![]() ![]() Country : India | vopani posted @ 2013-11-18 2:15 AM I finally got to participate in an LMI screen test! (after co-authoring the first, authoring the second and testing the third). Even though the B2: Repeated Neighbours has issues, I wanted to share what I did. '3' cannot occur in R5C1, R5C2, R5C3, R6C2 due to the puzzle rules. If '3' is in R6C3, it also has to be in R5C4 but since it is a 'Just One Cell' sudoku (so, non-unique), I submitted R6C1 as '3'. Pretty cheeky huh? Did anyone else get this weird funda? ;-) Also, an interesting thought about using 'uniqueness' in Just One Cell, it sounds funny though.

Hey my friend-despite-the-fact-you took-part-in-WPC, Interesting reasoning, although it is wrong. ![]() "...If '3' is in R6C3, it also has to be in R5C4..." you can conclude that 3 in R6C3 is not the answer of the JOC sudoku, but you can't conclude that 3 cannot be placed in R6C3 (it can be one of the multiple solution). I was in such a hurry about submitting my solution after having found the 3 in R5C4 that I didn't thought that it could not be possible, as it has to be in R6C3 as well (what I've seen however).

Lots of fun! Some of them were pretty darn hard, but most of them were perfect for the quick online solve. It was definitely in reach even for someone like me to finish within the time limit. A few of them were a lot harder to do without a pencil! A good memory exercise for me to see how much of that I could keep in my head. The colors interface would have been nice for bifurcating at times if I could have figured out how to make it work for me instead of changing the color of everything when I clicked on a color. | ||||||||||||||||||

Posts: 31 ![]() Country : United States | joshuazucker posted @ 2013-11-18 4:07 AM Oh, forgot to mention: the popup warning about just one cell was very confusing because I had filled in just one cell! So I worried that somehow the interface thought that I had submitted a puzzle with a non-1 number of filled-in cells. It would be nice to be warned about the warning. | ||||||||||||||||||

(Semax's point too) I agree, we should've said that this will happen. That'll be noted for next time (if at all we do variant JOCs again, that requires a think through in itself), and having a JOC in the example series on interface is also a good idea. | ||||||||||||||||||

In the solving interface, it would have to better if we could have been given different colors for backtracking the puzzles. | ||||||||||||||||||

Posts: 152 ![]() ![]() ![]() Country : United Kingdom | detuned posted @ 2013-11-18 5:59 PM I'd also like to know what is "incorrect" with my E5 - JOC5 - Killer solution. I entered R1C4 as a 6. The reasoning goes like this: 13 in the bottom right is either 256 or 346 - either way we certainly can't have R6C4 as 6. By the law of leftovers this means R1C3 cannot be a 6. The 6 in R1 must therefore go in C4 because it can't be part of a 7 or 8 cage... edit: n/m I see e5 seems to be missing on the results page, i assume it's a bad puzzle...

I certainly made liberal (ab)use of it... I agree, felt a lot faster on the harder puzzles once I started trying out things. Maybe one or two levels of undo to deal with actual typos? We actually discussed a lot about this, and it is the reason why we ensured that if you change color, it'll change throughout, meaning color changes are only for player preference rather than guesswork. With undo, we're not sure what is a great way of doing things. My point is someone solving could honestly make a mistake and it'd help to undo to retrace. So the only use isn't guesswork, and I'm always in favor of keeping things that help normal solving even if they could be used towards shortcuts, so we decided to keep it. Maybe restricting to one or two levels is a good idea, but I personally am still non-committal to the same. Would love to hear more views on it. I'll read back now to other points and queries. I only addressed the more pressing ones while I was away conducting a puzzle event here simultaneously over the weekend. | ||||||||||||||||||

There are so many situations where this is bad. Can you tell me one situation where this is good? It is probably the same reason why normal tests have a time limit instead of just saying, solve and submit whenever you like. Here the expected difficulty per grid is really low compared to normal tests, so a per grid time limit adds to the competitive aspect of things. In other words, I'd just say its easier and so we can experiment with a different quick-fire setting for it so we do. It is the general idea of a screen test (the same was used in WPC 2011 too) that we've tried to extend to Sudoku. The bigger challenge is in ensuring that at least most of these are easy enough for everyone to submit some in spite of time limits. Looking at the general feedback I feel at least that has been achieved this time. |
