The International Olympiad in Informatics (IOI) is an annual competitive programming competition and one of the International Science Olympiads for secondary school students. The first IOI was held in 1989 in Pravetz, Bulgaria.
Each country sends a team of up to four students, plus one team leader, one deputy leader, and guests. Students in each country are selected for their country's team through national computing contests. Students at the IOI compete on an individual basis. There is no official team ranking.
The contest consists of two days of solving six complicated algorithmic tasks by writing computer programs in C++.[1][2] All task materials are published on each year's contest website soon after the competition ends.
