David Levy was the organizer. The event was sponsored by [|AST], Walter Bannerman was supported by [|Unicible S.A.], [|Lausanne] and IBM, Lausanne . A few days later at the same place, [|Marion Tinsley] won the Checkers Man vs. Machine World Championship by virtue of a 4-2 score (with 33 draws) over [|Chinook]  .  The Heuristic Programming in Artificial Intelligence conference was again held during the 4th Computer Olympiad, but proceedings were not published. ||

Promotion Bug
In the round 3 game Chess 2175X vs. Genesis, Chris Whittington's program had a promotion bug, and only accepted a minor rook promotion after Genesis promoted to a queen. Arbiter Jaap van den Herik did not allow on the fly fixing of the bug during the game, since it was not I/O but search code, and judged to continue playing, allowing Whittington to correct the position, if Genesis played a diagonal "Rook move". However, Chess 2175X later played a move attacking the pseudo rook diagonally with its undefended queen and Whittington soon resigned. Next round, he withdrew from the tournament, which unfortunately left an odd number of participants.
