The Central European Olympiad in Informatics (CEOI) is an annual informatics competition for secondary school students.
The contestants compete individually, i.e. a team score is not calculated.
Competitors are selected through national competitive programming contests.
The contest consists of two days computer programming, solving problems of an algorithmic nature.
The structure of these competition days is described in the article about the International Olympiad in Informatics (IOI), which served as a role model for the more local CEOI.
