During the contest, all contestants will have to wear recognizable clothing provided by the organisation, unless explicit exemption is given by the organisation.
At least six problems will be posed. So far as possible, problems will avoid dependence on detailed knowledge of a particular applications area or particular contest language.

The jury has the right to change or withdraw problems during the contest. When this happens the jury will inform all teams.
Each team will use a single workstation. The organisation is responsible for determining that teams have reasonably equivalent computing resources.
A solution has to be written in C, C++(14), Python or Java (unless the problem statement explicitly states otherwise). Business teams can request other submission languages, on which the organisation will decide whether it will be made available for submission.
The jury decides per programming language which libraries and function calls are allowed to be used in the solutions. This will be published on website before the contest starts.

Each run is judged as accepted or rejected by a judge, and the team is notified of the results.
For each problem, the jury has a correct solution and test data.
A problem is solved when it is accepted by the judges. The judges are solely responsible for accepting or rejecting runs.
The winner of a pool is decided by (in order):
The team with the most correctly solved problems.
The team with the least total time. The total time 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 accepted run plus 20 penalty minutes for every rejected run for that problem regardless of submittal time. There is no time consumed for a problem that is not solved.
The team that first submitted its last accepted problem is ranked higher. In case a tie still remains, the team that first submitted its second-last accepted problem is ranked higher, and so on. In the event that this does not resolve the tie, the ranks will be determined by chance.
The jury is responsible for everything that has to do with the problem set and can be contacted for this through the ‘clarification requests’.
A team may be disqualified by the organisation or jury for any activity that jeopardises the contest such as dislodging extension cords, unauthorised modification, using of contest materials, using forbidden function or library calls, or distracting behaviour.
The organisation has the right to stop the contest, extending the contest time, temporarily block submissions for all teams or change the scores in exceptional conditions.
In situations to which no rule applies or there is ambiguity about the rules, the organisation decides.
