Abstract. The competition tasks at the International Olympiad in Informatics have evolved over its 20-year history. We distinguish three periods in this evolution and highlight it from various viewpoints. The 101 competition tasks are presented in a table that summarizes their task type and difficulty level, and that classifies them according to concepts involved in their problem and solution domains.
