Re: WPF Sudoku GP 2020

Well known is probably stretching things a bit :roll: personally I think that would apply to Extra Regions, Fortress and maybe Renban. I much preferred the balance of types in round 2 to be honest :D

It's not what I'd really call a 'logic' puzzle, but I've seen far worse sequences.
I'd call it maths homework :lol:

Re: WPF Puzzle GP 2020

Also note that for whatever values you put for the sequence, there will be a 6th order polynomial you can construct that fits the sequence. It’s a terrible puzzle for the GP.

Re: WPF Puzzle GP 2020

Quite annoyed to miscount 7 as 6 for the 59point nurikabe - that would have moved me up to 40th. I think it’s going to be pretty competitive behind Neil and James this year!

Re: 20th 24HPC in Budapest

I think me and Neil are planning on coming - we might even get our round together! The timing is a bit annoying from a UK perspective - there's a bank holiday on Friday which is doing funny things to the prices of flights as a few people are fancying a bit of a jolly in Budapest. My current plan is ...

Re: WPF Sudoku GP 2020

In general the classics points have been a bit weird. At a guess I’d say for any given puzzle one of the testers had a great time, perhaps after guessing or even restarting. I doubt that was the preferring for any one individual tester either! My strategy has been to ignore the lower point classics ...

Re: WPF Sudoku GP 2020

yeah I suspect that hidden clone caused more than a few people a spot of bother. I’m not at all sure I properly tweaked all of the logic. I just about tweaked that the regions might overlap, tried the top left shift and that just about worked with a bit of experimentation. Not sure how you’d have ru...

Looks like the contest is over: https://logic-masters.de/LM/2020/q_tabelle.php?id=127 Ken Endo solved all the puzzles because of course he did :) It's a bit complicated mixing up the German results with international, but as far as I can see from the UK: 12.

Re: WPF Puzzle GP 2020

There were lots of points for this round wich kind of meant puzzle selection was key. I'm a bit annoyed I missed the fillomino variant, and the tera XX as they were both relatively easy points compared to what I did do. Bad luck with answer keys Freddie, I assume 10/14 isn't all wild speculation and...

Re: WPF Sudoku GP 2020

Round 1 results. I thought that was pretty tough, and that seems to be backed up by only 12 solvers getting a full 13/13. I hope the GP's aren't going the same way as the USPC and the so-called "Snyder Effect" with the difficulty ratcheting up year on year. Top 3 UK preliminary results are: 39. Heat...

Re: Different Neighbours

I find the quickest way to solve harder examples is just to take a guess and hope you get to a contradiction sooner rather than later. There are a few techniques you can use before you need to resort to that though. Notating where numbers go across two adjacent cells can propagate very quickly acros...

Hi Liane, could you add some further details please?

Also, the price structure has always been a bit...

Re: What is a Sudoku? Report general consultation

Hi Fred, thanks for your comments, and I hope the finished report will better answer some of your questions.

Re: What is a Sudoku? Report general consultation

Hi Sam, thanks very much for the feedback! Agree on 1, the wording needs a bit of tightening up (and maybe also to try and use slightly less “technical” language 2 and 3 I’m hoping the final section will help clear up. You have to draw the line somewhere, and I’m certainly not going for full mathema...

What is a Sudoku? Report general consultation

Hi everyone, See this link for the current state of the report.  Sections 1-4 are complete, but 5 is incomplete (and will hopefully make the report more practical and understandable when complete). Given the timing, I think now would be the time to open this up to a more general consultation.  There...

Re: Puzzles at the Mind Sports Olympiad in London on Sunday

Nice! - getting the intended solution to that sequence I think makes you a very worthy winner Rodders. I have to say I think both me and Neil looked at it for a lot longer than 10/15 minutes so to get that intended answer was a really good bit of solving!

Re: Puzzles at the Mind Sports Olympiad in London on Sunday

I’m not sure it’s completely fair to put words into Prasanna’s mouth - I’d imagine he has his own take on it and has somehow managed to rationalise his decision. All I know is that regardless of anything else, if you’re supplying puzzles for competition, don’t reuse anything!

Some quick thoughts about the events. Sudoku: I think Neil had mentioned to me previously that the Mind Sports Olympiad tends to oscillate between being quite easy, to being very difficult. This year was a very difficult year! The format involved solving 8 Classics, 6 Diagonal, 6 Irregulars and 8 Ki...
