International Olympiad in Informatics (IOI)

The International Olympiad in Informatics (IOI) is the biggest international programming competition for secondary school students. More than 300 participants from 80 countries around the world participate each year.

Each country may send no more than 4 students to the competition, that's why most countries have national comptitions to select the IOI participants.

The IOI'18 will be held from 1-8 September in Tsukuba, Japan.
