  • Grader update

    Last couple of hours grader has been overloaded due to large number of malicious submissions indended to create large queue and make it impossible for other competitors to submit. The problem has now been resolved.

    Due to possible large queues we have introduced 15 second delay between the submissions for each account until the end of the contest.

    Thanks,

    Bubble Cup Crew

  • Changes to the grader machine

    Due the problems with grader machine we encountered yesterday, we decided to permanently change the grader machine for Round 2.

    To ensure same submission conditions, we regraded all yesterday's submissions. Unfortunately, this meant some of the yesterday's successful submissions failed by being too close to the time limit. Please try submitting the problem again to ensure it passes all testcases on the new grader.

    Sorry for the inconvenience,

    Bubble Cup Crew

  • New Bubble Cup Scoreboards are live


    Dear contestants,


    While you were busy solving Round 1 problems we were working on changing underlying database and improving scoreboard performance and looks. New scoreboards will now generate 2-3 times faster than before and also include country flags.

    We have also made an improvement to Individual profiles by displaying your current teams inside of them, and fixed problem with accounts getting signed out after 30 minutes even with "Remember me" option set.

    Please remember to finalize your teams soon, as you won't be able to edit them 48 hours after Round 2 starts.

    See you again in Round 2,

  • Time and memory limit updates

    We have noticed couple of solutions with the same big O notation as accepted solutions not passing due to different compiler optimizations. To fix this we decided to slightly increase time and memory limit constraints and regrade problems Arrow and Primitive Pythagorean Pairs.

    Travelling Knight is also getting an update to slightly increase the diversity of possible approaches.

    Updated time/memory constraints:

    Arrow: 2s/256MB -> 4s/256MB

    Primitive Pythagorean Pairs: 1s/128MB -> 2s/256MB

    Travelling Knight: 0.5s/512MB -> 1s/512MB

    Thanks,
