Participation and eligibility

Eligibility of CERC 2021 teams

The coach certifies the eligibility of contestants and serves as the official point-of-contact with the team prior to and during contest activities.

According to ICPC Regional Rules, all contestants have to be eligible by satisfying the Rules and the Eligibility Decision Tree. The host must bring a completed and signed eligibility form at registration. See the schedule for deadlines.

Participation fee

Since CERC 2021 will be performed online with local proctored teams, there is no participation fee.

Contest rules

General rules

The General Rules of the 2021 Regional Competitions are published on the ICPC website.

Technical rules

Teams

Only teams accepted by the Regional Contest Director can take part in the contest. All teams that want to participate have to check in at the registration desk on Friday, or Saturday morning (late registration). A team cannot compete in the CERC if the Participation Fee has not been paid in advance. No cash will be accepted during the registration.

Conduct of the Contest

All team members must attend all contest activities as specified in the schedule. The Coach is expected to attend or be available via phone during contest activities. Failure to attend any of the designated contest events can result possibly in the disqualification and forfeiture of any prizes. At least six problems will be posed. As far as possible, problems will avoid dependence on detailed knowledge of a particular applications area or a particular contest language. The language of the contest is English. All written contest materials and all communication with the contest officials will be in English. Contestants may bring resource materials such as books, manuals, notes and program listings. Contestants may not bring any machine-readable versions of software or data. Contestants may neither bring their own computers, computer terminals and calculators nor any kind of electronic devices such as headphones, radio sets, cellular phones, smart gadgets, etc.

As an exception to the previous rule, a team may bring their own keyboard (standard USB keyboard without wireless connectivity, etc.). The keyboard should be submitted to the organizer during the Registration.

Solutions to problems (source programs) submitted for judging are called submissions. Each submission is judged as accepted or rejected and the team is notified of the result. Additional information about the reason for the rejection is described in the contest system. A contestant may submit a question about a task through the judge system. If the judges agree that there is an ambiguity or error in the task statement, a clarification will be issued to all contestants. Contestants are not to converse with anyone except members of their own team and personnel designated by the Regional Contest Director. System support staff may advise contestants on system-related problems such as explaining system error messages. The contest will be held in a networked environment. The network may only be used to submit solutions, to ask questions, back up the solutions and to produce listings in ways designated by the organizers. Any other use of the network is strictly forbidden and shall result in immediate disqualification and removal from the contest area.

While the contest is scheduled to last five hours, the Regional Contest Director has the authority to alter the length of the contest in the event of unforeseen difficulties. Should the contest duration be altered, every attempt will be made to notify contestants in a timely and uniform manner.

A team may be disqualified by the Regional Contest Director for any activity that jeopardizes the contest, such as dislodging extension cords, unauthorized modification of contest materials (hardware of software), forbidden network activities or distracting behavior. The Regional Contest Director is solely responsible for ruling on unforeseen situations and interpreting these Rules.

Scoring of the Contest

A problem is solved when it is accepted by the judges. The judges are solely responsible for accepting or rejecting the submitted runs. In consultation with the judges, the Regional Contest Director determines the winners of the regional contest. The Regional Contest Director and judges have the authority to adjust for or adjudicate unforeseen events and conditions. Their decisions are final.

Team ranking details are described in the information page of the contest system.

Contest environment

The contest environment details are described in the information page of the contest system. The details may change up to the practice session.
