US Computer Go Competition History

The earliest computer go competitions were organized at the Usenix conferences in the early 80's.

The Ing Wei-Chi Educational Foundation and Acer sponsored the US Computer Go Championships at the US Go Congress, as preliminaries to their world championship, from 1988 to 1990.

David Fotland has organized and run the US competition since 1991.

Prizes

A plaque or certificate, and the admiration of your peers. The last four years there has been prize money available, with prizes for the first four or five places, and a prize for the best new program.

Any program can enter this contest and win prizes, no matter where it is from. The best new program prize will go to the highest finishing program that has not competed in a US computer go championship, Ing Cup, or FOST cup tournament.

The goal of this competition is to encourage computer go development, and see how well the programs play, so in areas not explicitly covered by the rules, the tournament director should make decisions in a way that can allow games to continue.

Rules

• Ing GOE rules will be used. All games will be even, without handicaps. Programs are not required to show the final score in Ing style. Komi is 8 points.
• Programs must be able to remove all stones, or indicate which stones they think are dead. If both programs pass thinking unsettled groups are alive, they are assumed alive for scoring purposes. The tournament referee will resolve any disagreement between programs on the status of groups after the game is over. Programs do not have to continue play.
• If a program makes an illegal move or refuses input of a legal move it loses immediately. Remember that GOE rules allow suicide. Several games have been lost in the past when one program committed suicide and the other would not accept the move.
• Mirror go is not allowed past move 60.
• Time limit is 120 moves for each side in one hour.
• Please provide your own computer at the contest site. Transportation costs and risks are borne by the contestant. We will provide a locked room, but the congress is not responsible for the loss of any equipment left there.
• Each program must be operated by an author, or designated representative. Each program can only be registered once.
• Participants should make a game record. These records are public and will be delivered to the AGA.
• Programs are encouraged to implement the computer go modem protocol to allow programs to play each other without human intervention. In a pairing, if one program has the modem protocol and the other doesn't, the program with the protocol gets 70 minutes instead of 60, to allow for operator time.
• If the modem protocol is not used, a go board will be used between the computers to record the official position. By mutual agreement the operators can decide not to use the go board, but then should be very careful to enter moves correctly.
• Programs can be restarted after a crash with the clock still running during the time it takes to restart or possibly reenter the moves.
• If the modem protocol is used, the time used will be taken from the programs own clocks provided they are in close agreement. Otherwise Ing clocks will be used by the operators. By mutual agreement between operators, clocks can be not used. In this case, if there is a crash, 20 minutes will be clocked for total recovery time from all crashes.
• If there is hardware failure, power failure, or disagreement about the position that can't be resolved and more than 150 moves have been played, and the referee can determine the likely result, the referee will adjudicate the game. Otherwise it will be played over.
• No change in go playing algorithm or program parameters is allowed during a game, but changes are permitted between rounds. If a program is playing too slowly and looks like it will lose on time, get the tournament referee. The operator will be allowed (one time only) to enter a command to adjust the computer's clock or playing level to speed it up when there is 10 minutes remaining on the clock.
• If there is enough time, a full round robin will be played. Ties from the round robin will be resolved by single elimination, with any bye's determined randomly. In the single elimination, game will be played with opposite colors from the games in the round robin. If we play round robin there will not be fixed round starting times.
• If there are too many entries for a round robin, a swiss tournament will be held with first round pairings determined by past results or by chance. In each round programs with the same number of wins will be paired if possible. No program will get more than one bye. A bye counts as a win. The same opponents will not be paired twice. The tournament referee has final say in the pairings.
• Tournament standings are determined first by number of wins, then by sum of defeated opponent's scores, then by sum of opponent's scores, then by head to head.
• All rule disputes are settled by the tournament referee.
