Rules
This is a contest in programming for teams of size 1-3. The teams will be presented with a collection of algorithmic programming challenges when the contest starts, and the winning team will be the one who solves the most problems successfully. Teams will receive feedback immediately on whether they solved a problem correctly or not.
Prize elegibility
Everyone is welcome to participate in the contest, unless someone in the team has had access to the problem set in advance. However, only students who are currently enrolled in courses at University of Bergen are eligible for prizes.
Scoring
Teams are ranked according to the most problems solved. Teams that are tied for amount of problems solved are ranked by least time penalty and, if need be, by the earliest time of submittal of the last accepted run.
The time penalty is the sum of the time consumed for each problem solved. The time consumed for a solved problem is the time elapsed from the beginning of the contest to the submittal of the first accepted run plus 20 extra penalty minutes for every previously rejected run for that problem. There is no time penalty for a problem that is not solved.
Accepted languages
We support all languages supported by Kattis. We guarantee that every problem can be solved in the languages Python 3, Java and C++. However, we do not guarantee that the same algorithm will neccessarily work in all languages.
