IOI - Past, Present, Future

The idea of initiating international olympiads in informatics for school students was proposed to the 24th General Conference of the United Nations Educational, Scientific and Cultural Organization (UNESCO) in Paris by the Bulgarian delegate Professor Blagovest Sendov in October 1987. This plan was included into the Fifth Main Program of UNESCO for the biennium 1988-1989 (Section 05 215). In May 1989, UNESCO initiated and sponsored the first International Olympiad in Informatics (IOI). (Quoted from the IOI'89 and IOI'92 Report). The first IOI was held in Bulgaria in 1989.

The IOI is one of five international science olympiads. The primary goal of the IOI is to stimulate interest in informatics (computing science) and information technology. Another important goal is to bring together exceptionally talented pupils from various countries and to have them share scientific and cultural experiences.

The IOI is organized annually in and by one of the participating countries. Each participating country typically sends a delegation of four contestants and two accompanying adults. Students compete individually and try to maximize their score by solving a set of informatics problems during two competition days. Cultural and recreational events are organized on the remaining days.

The competition tasks are of algorithmic nature; however, the contestants have to show such basic IT skills as problem analysis, design of algorithms and data structures, programming and testing. The winners of the IOI belong to the best young computer scientists in the world.

The IOI Regulations constitute the official definition of the IOI. The International Scientific Committee is responsible for a scientific content of the IOI. The International Committee supervises the IOI.

To decide next steps in the development of IOI Workshops and Conferences are organized.

There are several mailing lists for collaboration between members of IOI.
