Hello, Codeforces!
Microsoft Development Center Serbia is thrilled to announce the start of the 13th edition of Bubble Cup competition! Bubble Cup is an international, ACM-style team contest aimed at university and high school students.
You can register and take part in the competition on the BubbleCup website. Qualifications consist of two online rounds which start on the 1st of April and on the 1st of May and last for 25 days each. Both online rounds will feature around 10 problems selected from various Online Judges, including at least one challenge problem!
The best 16 teams will compete in the 5-hour long finals in Belgrade, Serbia, tentative date being September 2020 due to COVID-19 situation.
Biggest change in the rules from the previous iterations is that now for any country other than Serbia there can be at most 2 teams in the finals. Please check the updates rules on the BubbleCup website.
You can find problems from previous finals on our Codeforces online mirror competitions:
Bubble Cup X — Finals [Online Mirror]
Bubble Cup 11 — Finals [Online Mirror, Div. 1]
Bubble Cup 12 — Finals [Online Mirror, unrated, Div. 1]
We wish you best of luck in competition! Let the coding begin!
It will be cool if we will see score of submission on challenge problem. Is it possible to do?
It is only possible to see the highest score which one of your submissions has achieved which is kinda annoying when you try to upgrade your solution and don't know if it is achieving at least a similar result as the best one so far. One possible work around is to submit in SPOJ but the time limit there is a little bit stricter than it is in the Bubble Cup system so it is not exactly the same.
Also checker on SPOJ seems to be broken, as you can get negative score.
Is there rule meaning that not just the top X will advance to the finals?
Yep, top2 from each country.
Also there is a wildcard rule and the only one was given to team DEUSSS.
