The IOI 2019 Azerbaijan brought together more than 300 talented young people who showcased their skills in the most prestigious computer science competition in the world.

Please make sure to check the official IOI 2019 website for the results/scoreboard, tasks, photos and newsletters. 

All participants (contestants, leaders, guests, committees, etc.) are invited to spend 5 minutes and fill the online feedback and survey form (sent to your email address). Feedback and suggestions regarding IOI 2019 can help the IOI community to better organize the future IOI competitions.

Finally, the host organizers hope that IOI 2019 also helped you to learn more about Azerbaijan, the Land of Fire. Similarly, the IOI 2019 Azerbaijan Host Organizing Committee hopes that you liked the City of Winds, and will visit Baku again, to explore more, to travel, or maybe to study or to teach.
