Nilz - 2016-02-17 12:19 AM

Is there an error in today's solution? I'm fairly sure I've solved it, but it's not letting me submit. Of course, it's possible I'm being an idiot, but I've triple-checked!


Nilz - 2016-02-17 12:21 AM

Hmm, it just let me submit 7 minutes later and I'm certain I didn't change anything- could you check my solve please and fix my time if you can see that I had the correct solution earlier (if this is possible)? Thanks.


The solution has been corrected. That is the reason your submission was accepted. I'm working on getting your (and Ivan's and some other players') timing correct.

CTC Scoring system

The scoring system and formula are exactly same as previous years.

  • Submissions within 60 minutes will be considered for scoring
  • 2 minutes penalty for each wrong submission
  • 15% time penalty for each late day (maximum 2 late days are allowed – so a puzzle can be solved upto 72 hours after it is uploaded)
  • Each puzzle has its own points, which is computed from solving times of top 10% players on that day.
  • Each player gets points for solving a puzzle based on own solving time and others’ solving times. Exponential distribution is used.
  • Total points for a player is sum of puzzle points over 7 weeks.

Just curious -- when there are a lot of people who did not finish the puzzle (as with today's), do they get factored into the calculation for MED?

For scoring purpose, only players with CoTI <= 1 hour is considered. All DNFs are ignored.

For example, if you go to 14th Feb's in the score page, you should see a line at the top :

Results for 2016-02-14's puzzle / Num Players : 200 / Top 10% : 20 / Top 10% AVE : 102.1950 / PuPo : 10.1091 / MED : 275.5600
All 5 DNFs are ignored. All 3 players with CoTi > 3600 are ignored too.

I hope Serkan's hand is better!


Recently I had an operation, in these days the time is not by my side, it flows very slowly, and I'm perceiving so much pain than I'd already have, I'm living a delusion :). Also I've figured how hard to able to write :). I have so much pain, but I hope that in next 10 days it will be better for me.

Thanks for asking


I know what you mean -- when I'm not well, it feels like the days last forever, and I just can't wait for the day I'm all better.

Hope that day is coming for you soon.

I could not submit my solution (18th Feb) when I finished solving it (about 20 minutes before deadline). I tried again then some minutes later again but could submit only after a half hour.

Timing adjusted for anurag, chaotic_iak, litleboy, nilz, prasanna16391, TiiT
prasanna16391 commented at 2016-02-17 01:01:16
Not sure how to rate this one. I re-solved it later with some very narrow connectivity logic, which was excellent and a lot of fun. But I just don't think that this was something most people would be able to see with a timer running, and with the big size its more of a lottery for someone who just intuitively solves for the middle being empty. .
brecher92 commented at 2016-02-17 02:39:14
I still don't see the logic with the 1-1-3 on the left side. I'm looking at a few other people's solves and see that this was handled early on, but I don't see how.
achan1058 commented at 2016-02-17 02:52:56
I do not understand this puzzle. The amount of guesses I have made is insane.
achan1058 commented at 2016-02-17 02:57:55
By the way, how do you view other people's solve?
detuned commented at 2016-02-17 03:50:30

very hard.
swaroop2011 commented at 2016-02-17 06:50:16
half of the puzzle i could solve it logically. But later had to guess couple of times which didn't went my way.
anderson commented at 2016-02-17 10:24:49
I guessed the 1-1-3 on the left side and got lucky because that guess propagated through the whole puzzle. Looking at it again, I'm having a lot of trouble completing it logically (i.e. not looking more than 2 steps ahead).
MrLiang commented at 2016-02-17 11:19:53
Ahh!! brain block. It's look like "Puzzle Marathon" for me. :(
tamz29 commented at 2016-02-17 15:47:36
Should've guessed earlier :/
rob commented at 2016-02-17 17:18:02
I only figured out that left area towards the end, with some not-quite-rigorous solving before (though the middle area being empty was necessary due to uniqueness at some point). But it's possible to start there. The core restriction there is that the bottom right cell of the 113 can't be isolated, else it breaks the single 4 together with the 24 and the 33 below. Then you can deduce that the top left cell of the 113 has to escape upwards past the 14, and the top left corner can be resolved.
gareth commented at 2016-02-18 00:16:34
Far too hard for a daily puzzle - I had to give up since I couldn't spend long enough on it, and come back the next day. If a puzzle is extremely hard without warning then it's unreasonable to expect people to magically have enough time set aside at the moment they discover this. It also takes away the fun of it, and means those who don't have other commitments have a definite advantage. ;)

As it happened a few days ago, an incorrect solution seems to have been entered in the background. That is fixed now, and the timings of the 'incorrect' submissions which match the actual solution will be in the system and edited to reflect on the score page soon.
