The 23rd Computer Olympiad was held November/December 2020. As a consequence of the global pandemic, for the first time the competitions were fought online. This involved creating new rules that were, in large part, dependent on having the participants cooperate on organizing and conducting the events. The event was a success and will be repeated online in 2021.
