SWERC follows the ICPC regional contest rules.

Exceptionally this year, because the contest will take place online, some of these regulations are changed. The modified parts are in bold.


The SWERC eligibility criteria are those outlined in the regional contest rules. In particular, all contestants must satisfy the 2020 eligibility decision tree. Contestants must be students registered at a university in the SWERC region, and must be able to prove this fact (with a student card, a proof of enrollment, or some other official document).

Contest material

Exceptionally this year, and unlike from the rules of the world finals contestants are allowed to use their own computers and electronic devices, and to use one computer per team member.

The rules about Team Reference Document ("notebooks") and about using the Internet will be announced here later.

Team members are not allowed to communicate with the outside world during the contest, or to share any information about the contest problems or about their own solutions before the contest ends.

Programming languages

The main programming languages of SWERC are C, C++, and Java. In addition, the contestants have the option of using Kotlin, OCaml, or Python. Note that OCaml can only be used at SWERC, not during the World Finals.


The scoring rules are the ones described in the ICPC regional contest rules. We clarify that the total time of teams is measured in minutes (not seconds).

In case there is a tie, the following local tie-breaking rule is used (from the SWERC 2016 page): If two teams solve the same number of problems and have the same total time, 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.

Team composition

All teams who want to participate have to follow the registration procedure as described in the registration page. There is no onsite attendance requirement this year.

Registration is open to institutions from Portugal, Spain, France, Italy, Switzerland, and Israel. By special request teams from other countries may be allowed to participate in this region. Further, as per the regional contest rules:

An institution may send contestants to only one regional contest in a given year.

The rules pertaining to the number of teams that may be sent by each institution are described on the registration page.

Code of conduct

We are dedicated to providing a harassment-free experience for everyone, regardless of gender, gender identity and expression, age, sexual orientation, disability, physical appearance, body size, race, ethnicity, or religion (or lack thereof). We do not tolerate harassment of SWERC participants in any form. Sexual language and imagery is not appropriate during SWERC, including talks, contests, and social events. Participants violating these rules may be expelled from SWERC without a refund at the discretion of the organizers.

If you are being harassed, notice that someone else is being harassed, or have any other concerns, please contact the organizers.

(The SWERC code of conduct is inspired by Conference Code of Conduct.)

Insurance and expenses

The SWERC organizers do not cover the accommodation, transportation, and other expenses of participating teams.

Each team should make sure that they have appropriate insurance (e.g., against accidents or diseases) to participate to SWERC. Insurance is the responsibility of the teams, not of SWERC organizers.

SWERC organizers do not accept any responsibility for the personal belongings of participants at the contest venue. In particular, contestants should be aware that some belongings, such as electronic devices, cannot be taken to the contest area (see contest material). Contestants are advised to leave such items under the responsibility of a trusted party (e.g., the team coach), or not to bring them at the contest venue altogether.

Intellectual property

The SWERC organizers do not assert copyright on any code written at SWERC, and do not require SWERC competitors or coaches to license their code in any specific way. Solutions submitted by SWERC contestants will not be distributed to third parties without the consent of their authors.

Likewise, in Team Reference Documents, we allow contestants to use third-party code that they have not written, including copyrighted code; and we allow them to use this code in their solutions to SWERC problems. However, it is the responsibility of contestants to ensure that their use of third-party code in Team Reference Documents and in SWERC solutions is compliant with any copyright requirements that apply to this third-party code. SWERC organizers accept no responsibility for any legal consequences arising from such use.
