Computer Olympiad

Not to be confused with International Olympiad in Informatics or its many feeder competitions like the United States of America Computing Olympiad.

The Computer Olympiad is a multi-games event in which computer programs compete against each other. For many games, the Computer Olympiads are an opportunity to claim the "world's best computer player" title. First contested in 1989, the majority of the games are board games but other games such as bridge take place as well. In 2010, several puzzles were included in the competition.

Developed in the 1980s by David Levy, the first Computer Olympiad took place in 1989 at the Park Lane Hotel in London. The games ran on a yearly basis until after the 1992 games, when the Olympiad's ruling committee was unable to find a new organiser. This resulted in the games being suspended until 2000 when the Mind Sports Olympiad resurrected them. Recently, the International Computer Games Association (ICGA) has adopted the Computer Olympiad and tries to organise the event on an annual basis.

Bridge

Main article: Contract bridge

A bridge hand being played

Bridge is a trick-taking card game for four players.

Bridge participation in the Computer Olympiad was largely discontinued when in 1996 the American Contract Bridge League established a new official World Computer Bridge Championship, to be run annually at a major bridge tournament. Starting in 1999, that event is now co-sponsored by the World Bridge Federation.
