The most important at a glance:


The problem set will be available in English only.


We have updated the rules again; there is no more age limit.

There are two categories in which teams will be divided: "students" and "professionals". The category "students" will contain teams which consist only of students currently enrolled in a Swiss educational institution (including exchange students), and who have not yet obtained a Master's degree. 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".

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 organizers will suggest merging teams when appropriate (with the consent of all concerned people).

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.

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 algorithmic problems that may be divided into 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.
