KTH Challenge 2013 online contest
By lukasP, 11 years ago, In English

We organize a programming contest at KTH in Stockholm next Sunday, April 21, 11:00 — 15:00 CEST. You can register now for the online contest and solve some warm-up problems from the last year's contest. The problems in the real contest will be of similar character and difficulty, they were done by almost the same people after all. The allowed languages are C/C++, Java, Python, C# and Go, but Python might be too slow for some problems.

For people going to the World Finals this is a great opportunity to try out the Kattis contest system.

Btw, the contest also has an on-site competition happening at KTH in Stockholm, but only for university and high school students.

I hope you will have fun!

I just want to remind you all that the contest is tomorrow. I am curious if you manage to solve the hardest problem.

          Sorry, we thought we could open the registration for a bit longer, but we are now busy with other stuff.

Sorry everyone, I missed that Scrool (the guys running the judge) had to close the registration, so I didn't emphasize that you should register beforehand. We'll make it better next year!

Added as a contest in the Gym — 2013 KTH Challenge. Two issues:

  • I wrote a checker for E because the output is not unique. I think it is good idea (and good style) to publish jury's checker programs.
  • I found that the answer on the test 28 (problem E) seems to be incorrect. I replaced it with the output generated by one of the solutions.

    The checker in now available on the website.

    Yes, the output was incorrect, it's fixed now. The checker was not reading it anyway, because it's always possible to transform the graphs.

    We decided to publish the problem packages including testdata, wrong solutions, generators and validators.
