This week, the Central European Olympiad in Informatics 2023 (CEOI 2023) is going to take place! CEOI is a programming contest for secondary school students from countries in Central Europe. Around 50 contestants from Croatia, the Czech Republic, Germany, Hungary, Poland, Romania, Slovakia, Slovenia, and our guest countries Israel, Switzerland, and Ukraine will compete against each other, solving difficult problems of algorithmic nature. Each participating country sends 4 contestants from their national olympiads which take place in the months beforehand.

The contest consists of two days, Tuesday and Thursday, on each of which the contestants have 5 hours to solve 3 problems of varying difficulty. Each problem is worth 100 points that are distributed into multiple subtasks with different constraints that allow the participants to earn partial scores.

CEOI 2023 is hosted in Magdeburg, state capital of Saxony-Anhalt and among the most historical cities of Germany. There will be a live scoreboard during the two competition days, and we will host an online mirror around a week after CEOI. For more information about the contest, visit the official website at ceoi2023.de.

We wish all CEOI contestants an enjoyable contest and a good time in Magdeburg!
