The International Olympiad in Informatics is one of several international science Olympiads held annually around the world. Exceptional high school students from various countries compete in the prestigious algorithmic competition to sharpen their informatics skills—such as problem analysis, design of algorithms and data structures, programming, and testing.
Main Objective
- To discover, encourage, challenge, and recognise exceptional high school students for their talent in the field of informatics.
- To foster friendly international relationships among computer scientists and informatics educators.
- To bring the discipline of informatics to the attention of young people.
- To promote the organization of informatics competitions for high school students.
- To encourage countries to organise future IOI.
Each participating country selects a team of up to four contestants to represent their nation. The team, accompanied by a team leader and deputy leader, will compete in a two-day competition. Each contestant competes individually to maximize their score by solving three algorithmic problems within five hours.
Participation in IOI is not directly open to individuals. Each participating country sends a team of four students and selection is coordinated through a national competition.
If your country is not listed on the Members page of the IOI, you need to approach an organization that is capable of initiating such an activity in your country. For instance, it could be an organization that already conducts Olympiads in other subjects such as Mathematics or Physics. You should ask someone from this organization to contact the Secretary of IOI for more information about the procedure for new countries to join IOI.
