The British Informatics Olympiad is the computing competition for schools and colleges. We are proud to present BIO 2023.
The 2023 British Informatics Olympiad

Eligibility

 

The British Informatics Olympiad (BIO) is open to students under 19 years of age and studying full-time at an establishment of Secondary or Further (not Higher) Education in mainland Britain. Entries are co-ordinated by the Head of Information Technology or another member of staff at the school or college (teacher in charge).

A similar competition exists for students in Northern Ireland and the Republic of Ireland.

Structure of the first round

 

The first round of the BIO consists of a 3-hour paper, with three questions, to be taken in school. Each question is to be solved by writing a computer program, on any type of computer and in any language; the questions will be supplemented by written problems.

The exam will be taken on a day of the school's choosing, but marks must be submitted electronically by 15 January if they are to be considered for the final.

Answers consist of the student's computer programs (which should be stored electronically), the written answers to the problems, and the results of the tests specified in the marks scheme.

The answers are to be marked by the teacher in charge. Marks should be submitted on the form which will be described on the marks scheme. All answers should be retained by the teacher in charge and may, for moderation, be required at short notice by the BIO organisers.

Structure of the final

 

The final will take place in Cambridge during the Easter holiday, 2023. The best 15 competitors in the first round of the BIO will be invited to take part.

Food and accommodation will be paid for by the BIO.

The final will consist of a series of written and programming problems. The machines used for the final are expected to be running Linux. The programming language available will be C/C++. There will be an opportunity for students to use the contest environment prior to contest.

The four winners of the BIO and a team reserve will be selected at the final, and will be announced at a presentation ceremony on the last day.

International Olympiad in Informatics

 

The four winners will form the team to represent Britain at the International Olympiad in Informatics (IOI). In the event of one of these being unable to attend IOI 2023, a reserve will be substituted at the organisers' discretion.

The IOI will take place in Hungary in August 2023. All expenses of travel (with the UK and between the UK and the IOI), food and accommodation will be covered by the BIO and IOI, although team-members are advised to bring their own pocket money.

The team will be accompanied by at least two team leaders.

The team members will compete as individuals against approximately 350 students from 90 countries, solving problems using computers; the best students will receive gold, silver or bronze medals.

Interpretation

 

The Chairman, Director(s) and Secretary of the British Informatics Olympiad will have the final say in the interpretation of these rules, and any ambiguity or question should be referred to them.
