- May participate for free.
- Exists of students from the same institution and who are not participating in another team. The institutions must be located in either Belgium, Luxembourg or The Netherlands.
- Has a coach, which is the contact person of a team. This can be a team member or a student or faculty member of the institution.
- Participates in the student teams pool for the title “Winner of the Benelux Algorithm Programming Contest 2020”.

The Contest
Introduction
- The language of the contest is English. All written contest materials will be in English.
- The contest lasts for 5 hours.
- From the beginning until one hour before the end of the BAPC, the scores are displayed.
Problems
- At least six problems will be posed. So far as possible, problems will avoid dependence on detailed knowledge of a particular applications area or a particular contest language.
- A contestant may submit a claim of ambiguity or error in a problem statement by submitting a clarification request to a judge. If the judges agree that an ambiguity or error exists, a clarification will be issued to all contestants.
- The jury has the right to change or withdraw problems during the contest. When this happens the jury will inform all teams.
System
- Each team will use at most three workstations, i.e. at most one computer per team member.
- A solution for a problem has to be written in C99, C++ (version 14 or later will be available), Python (versions 3 will be available), Java (version 11 or later) or Kotlin (version 1.3), 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.
- A team is disqualified if they submit harmful code that disrupts the contest
- For every solution, only the standard library of the chosen language may be used, i.e. no other function calls can be made.
- There is no explicit restriction on internet access during the contest. However, the organisation discourages copying code from reference materials as solutions will be checked on similarities. If there is suspicion of plagiarism among teams, both teams are subject to disqualification.
Judgement
- 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 the pool is decided by (in order):
- The team with most correctly solved problems.
- The team with the least total time. The total time is the sum of the time elapsed from the beginning of the contest to the submission of the accepted run plus 20 penalty minutes for every rejected run for that problem regardless of the submission 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”.
Special Rules
- A team may be disqualified by the organisation or jury for any activity that jeopardises the contest such as dislodging extension cords, unauthorised modification, unintended use 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.
- If necessary, the organisation can make changes and exceptions to the rules.
