The problem set will be available in English, French and German.


We've updated the eligibility criteria and people which are not students now can also participate!

There are two categories in which teams will be divided: "students" and "professionals". The category "students" will contain teams which consist only of students pursuing a master's degree or lower, currently enrolled in a Swiss educational institution (high school, HES, university, ETH or vocational school) or currently enrolled in a foreign educational institution but doing a bachelor/master thesis in Switzerland. Teams that contain at least one predoctoral/PhD student or one person that does not fulfill the above defined "student" criteria will be part of the category "professionals". All members of all teams must be between the ages 14 and 28 (included).

There will be a separate ranking for the student category, and both categories can win attractive prizes.

Individuals without a team may also register. The judges will try to form balanced teams (to the best of their abilities) out of all individuals who are not yet in a team.

There will be a task to be solved after registration. Deadline to solve it is 8 hours after the registration deadline.

Participation fees

The participation fees are 5 CHF per contestant. The fee will have to be payed at the latest 2 days after the registration deadline.

Conduct of the contest

The Contest will be preceded by a dry run. The aim of the dry run is to get the contestants acquainted with the judging system. All data on the team’s computers will be erased after the dry run.
The Contest duration is 4 hours and 30 minutes.
The Contest features between four and eight algorithmic problems, divided into three sub-problems (more details on the info page).
The Contest will take place on modern computers running our specialized contest environment. You can find all the details at the contest environment page.
The participants may request the organizers to print their source code in order to help with the debugging.

Scoring system

Teams will be ranked according to the total number of sub-problems they solve correctly. There will be no partial credit.

During the last hour of the Contest, the ranking display will be frozen and the winners will only be announced at the HC2 Diploma Ceremony.
