11. When selecting moves to play in the actual game (not playouts) superko is checked and forbidden. positional superko (as opposed to situational superko). - Dave Hillis -----Original Message----- From: Don Dailey <[EMAIL PROTECTED]> To: computer-go <computer-go@computer-go.org> Sent: Sat, 11 Oct 2008 9:11 am Subject: [computer-go] simple MC reference bot and specification On Sat, 2008-10-11 at 13:33 +0100, Claus Reinke wrote: > I have a rough idea of what that might be.

I'm going to publish a real simple java reference program and some docs to go with it and a program to "test" it for black box conformance. (Actually, it will test 2 or more and compare them.) I would like to get someone who writes better than I do to write up the standard in less casual language but it goes something like this: 1. A complete game playing program so it can also be tested in real games. 2. Play uniformly random moves except to 1 pt eyes and avoiding simple ko. When a move is otherwise not possible, pass. 3. Playout ends after 2 consecutive pass moves (1 for each side.) 4. 1 pt eye is an empty point surrounded by friendly stones for the side to move. Additionally, we have 2 cases. If the stone is NOT on any edge (where the corner is an edge) there must be no more than one diagonal enemy stone. If the point in question is on the edge, there must be NO diagonal enemy stones. 5. In the playouts, statistics are taken on moves played during the playouts. If the move is played FIRST (during the playout) by the side to move it is one data point and the win loss record is maintained. 6. The move with the highest statistical win rate is the one selected for move in the actual game. 7. In the case of moves with even scores a random selection is made. 8. Pass move are never selected as the final move to play unless no other non-eye filling move is possible. 9. Random number generator is unspecified - your program should simply pass the black box test and as a further optional test your program should score close to 50% against other "properly implemented" programs. 10. Suicide not allowed in the playouts or in games it plays. 11. When selecting moves to play in the actual game (not playouts) superko is checked and forbidden. 12. If a move has NO STATS taken (which is highly unlikely unless you do very few playouts) it is ignored for move selection. Did I miss anything? I would like to get feedback and agreement on this. Please note - a few GTP commands will be added in order to instrument any conforming programs. Haven't figured those out yet, but it will be designed so that it can report number of nodes, number of playouts, average score of playouts, etc. So the tester may set up some position and a ko, and ask for statistics based on the number of specified playouts. - Don _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
