Central-European Olympiad in Informatics


The Central European Olympiad in Informatics (CEOI) is an annual informatics competition for secondary school students. Each of the participating central European countries sends a team of up to four contestants, a team leader and a deputy team leader.

Central-European Olympiad in Informatics (CEOI) aims at motivating secondary school students of Central Europe to:

  • get more interested in informatics and information technology in general,
  • test and prove their competence in solving problems with the help of computers,
  • exchange knowledge and experience with other students of similar interest and qualification,
  • establish personal contacts with young people of the Central European region.

Additionally, the CEOI may:

  • provide training for the students participating in the International Olympiad in Informatics (IOI),
  • initiate discussion and cooperation in informatics education in the secondary schools of the Central European countries.

Delegations from the Croatia, Czech Republic, Germany, Hungary, Poland, Romania, Slovakia and Slovenia are invited as regular participants.

The contestants compete individually, i.e. a team score is not calculated. Competitors are selected through national computing contests.

The contest consists of two days of computer programming, solving problems of an algorithmic nature. The rules and regulations of the contest resemble the rules and regulations of the International Olympiad in Informatics (IOI), which served as a role model for the invention of the more local CEOI.

The first CEOI was held in 1994 (Romania, founder of the CEOI), five years after the first IOI.
