The International Olympiad in Informatics (IOI) is one of the most recognized computer science competitions in the world. The competition tasks are of an 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 CEMC was proud to host the 22nd International Olympiad in Informatics held August 14 - 21, 2010 at the University of Waterloo. |
Canada's entry into the annual IOI competition is determined by performance on the Canadian Computing Competition. The table below lists Canada's past results.
