2015 Sudoku GP

Post by detuned » Sun 04 Jan, 2015 11:18 pm

We don't have a thread for this one; what with all my travelling around this weekend I'm quite grateful there is an opportunity to give this a crack tomorrow evening.

N.B. you will need to register to participate if you have not done so already for the 2014 Sudoku/Puzzle GP

I think whichever way I try, this isn't going to quite look right. UK Results for round 1:

1.	David McNeill	UK		495	13	13	01:20:07

My showing was good enough for 49th - a little disappointing personally speaking but I didn't have too much preparation. Good to see some new UK names on the list!

Good work, David, Tom & Heather. Not a great set of puzzles for me, and I chose badly, despite not wasting any time on Thermo & Arrow, both of which did not work out well post-event. Good to see so many total entrants, 494 troubling the scorers, which reconciles me to being outside the top 100.

Sudoku GP Round 2 results (UK) from http://gp.worldpuzzle.org/content/offic ... sudoku-2-0 :

Name Country Pts Sent Ok Time
Mark Goodliffe UK 510 12 12 01:07:41
Adam Bissett UK 480 12 11 01:22:48
Tom Collyer UK 475 13 11 01:28:49
Heather Golding UK 395 11 10 01:24:42
Mike Colloby UK 300 6 6 01:28:10
Saul Glasman UK 275 8 8 01:22:32
David Collison UK 240 7 7 01:29:30
Sam Boden UK 235 5 5 01:01:31
Charley Parsons UK 190 6 6 01:09:49
Jennifer Warrender UK 190 6 6 01:24:37
George Michael UK 75 3 2 01:10:09

My 510 was tied with 30 other people for 56th place, all of whom presumably couldn't do Puzzle 13. Despite 23 minutes (plus a couple at the start) on the Battleships, I couldn't crack it, due to a (repeated) mistaken assumption about the middle row (it was a lovely puzzle, as I worked out afterwards). I thought, when I checked the rules about applying for bonus points, you could only do that with a full submission - is that wrong? Not something I've had to consider before...

Well done, Adam, by the way.

I had a discussion with the organisers last year along those lines. My understanding is that to gain bonus points you may only have a minor error (e.g. two digits swapped) in one of your puzzles, and so you can't get any bonus points if you miss a puzzle entirely or enter a blatantly wrong answer for it.

Thanks James,

That explains bonus points awarded to those without 13 correct solutions, and also that I am yet to be in a position to push that magic button. It might even explain why the marking process seems to take 24 hours when I was expecting there was an algorithm to do it all. I'm a little shocked that the application of the system is so logical and sensible though...

Round 3 results are up: http://gp.worldpuzzle.org/content/offic ... sudoku-3-0

The UK piece is:
1. Tom Collyer.......... UK 560 13 13 01:19:17
2. Mark Goodliffe ...... UK 520 11 11 01:30:00
3. Heather Golding .... UK 495 12 12 01:27:29
4. David Cook........... UK 310 9 9 01:28:05
5. Roderick Grafton ... UK 290 6 6 01:29:56
6. Adam Bissett ....... UK 290 8 8 01:30:00
7. Charley Parsons .... UK 235 8 8 01:27:33
8. Saul Glasman ....... UK 230 7 6 01:29:35
9. Mike Colloby ........ UK 175 4 4 00:56:59
10. Jennifer Warrender UK 120 6 4 01:27:48

Confession: I would have been marked as 55 pts less, but the markers generously accepted my plea for credit after the webpage (or my browser) glitched in the middle, causing me to refresh it and not realise it hadn't saved a 30-pt solution - this also contributed to me being 3 seconds late with a 25 pt solution. Well done, Tom and Heather. Tom, I totally agree with the decision to leave the Consecutive Quads puzzle till the end - heavily undervalued at 40 pts.

I actually thought the consecutive quads in the competition was pretty easy - although I left it til afterwards having got totally stuck on the one in the instruction booklet.
It's very interesting which rounds we as a country seem to do well on...

I do wish I had woken up to the fact that the competition started in January - might struggle to get six of the rounds done. It has at least highlighted the types I need to practice (a lot!)

Actually, Heather, I agree that the Instruction Book example was much harder, and took me ages. In fact, my Instruction Book performance would have been disastrous as I broke at least 3 of the variants there. I also agree with Cooky that the best thing(!) about the GP is it shows you your weaknesses (but also your strengths).

So, did I miss an email or was I simply stupid enough to think that the previous emails on 31/12 and 27/01 meant that last year's feedback had been taken on board ?

I'm glad to go error-free for the first time this year!

I don't recall solving a consecutive quads before, I hadn't looked at the instructions. I suspect with even a little preparation I should have been able to get this set finished, but there's always another time :) A very encouraging set of UK results nevertheless!

Haha, I've made a point of solving it now. It wasn't that hard, although perhaps a conducive to silly errors, which probably explains why my guessing potshot approach to it during competition didn't work so well!

Thanks, Heather. I can't deny it was exciting to press 'Claim Bonus' for the first time!

Very well done Mark. The Classics were all quite tricky. And some of the later puzzles took time as well.

My submission wasn't logged. I have just heard from Karel to say that my first submission was after the contest had ended!
