About the International Olympiad in Informatics: Empowering Young Minds Through Algorithmic Thinking

The International Olympiad in Informatics (IOI) is one of the most prestigious global competitions in computer science for secondary school students. Established in 1989 under the auspices of UNESCO, the IOI was created to foster interest in informatics and information technology, and to bring together the brightest young programmers from around the world.

The competition is overseen by the IOI International Committee, which sets policies and guidelines, while each edition is organized by a different host country’s national informatics organization—typically supported by their ministry of education or a major academic institution. These hosts are responsible for developing original tasks and managing the logistics of the event.

Focused on algorithmic problem-solving and programming, the IOI challenges participants with complex tasks that require deep logical reasoning, creativity, and precision. It aims to promote excellence in computing education while also encouraging cultural exchange and international collaboration.

Now in its fourth decade, the IOI has grown to include over 90 participating countries. It continues to inspire the next generation of computer scientists and software engineers by offering a platform where talent, perseverance, and innovation are celebrated on a global stage.
