Re: Results of the 2nd UEC Cup (Re: [computer-go] UEC cup)
Thank you for your suggestion David.

You can seed a swiss competition so it is likely that the best programs will meet in the last round. Well, we have thought of making the games shorter, but we were concerned of the effect it might give to the results of the tournament. #I understand that shorter games will work against MC based programs. If 40 minutes is too long for most programs, we would certainly like to move to shorter games.

Re: [computer-go] Format of the UEC Cup
Thank you for you suggestions, Rémi. To tell the truth, I was also surprised by the format of the tournament when I first heard it last year, and still in doubt if it is a good way to organize the tournament. #Especially when the top four programs get seeded next year. I did not come up with the idea of having no seeds, it is certainly worth discussing. Organizing a 'minor league' is difficult due to the number of participants and the availability of space, but we might be able to organize one if we are able to afford more rooms.

We know that we are sacrificing accuracy, and do want to know what the participants (and might-be-participants) think about how the tournament should be organized. #This includes opinions on how should remote attendance be allowed At first, I was also surprised by the format of the tournament. From a statistical point of view, it certainly does not rank participants in the most accurate possible order. But the ranking of a 9-round tournament always depends a lot on luck, anyways. The advantage of direct elimination is that there is no risk of tie, and it makes the final rounds more exciting. I think the format is very good. Still, I have a couple suggestions. First, it might be better to let everybody play in the qualification tournament, even the previous top 4. The quality of pairings in the second day depends a lot on the quality of ranking of the qualification tournament. Strong programs would have no difficulty to qualify, anyways. And a program that loses a game because of technical problems can try to fix the technical problem for the next game (or the next day). Also, some participants may feel frustrated that they were eliminated in the first day. Maybe they could play swiss between them in the second day. Regarding remote play, I don't like it, but that is probably because I don't profit from it, whereas my strongest opponents do :-) It seems that the UEC Cup is very well organized, and I thank you very much for your work.

[computer-go] The first Go UEC cup
Dear all, As most of you know, Gifu Challenge was canceled for this year. Instead, there will be a computer go competition held by the Cognitive Science and Entertainment (EC) Research Station of the University of Electro-communications. Unfortunately, we are not able to provide prize money for this competition. As with Gifu Challenge, some number of deputy operators will be available, so you can attend the competition even if you cannot come to Tokyo. As we might not be able to provide operators as much as the Gifu Challenge, please contact us early if you require a deputy operator. The announcement follows: Cognitive Science and Entertainment (EC) Research Station of the University of Electro-communications, are organizing the first Computer Go UEC Cup during December 1-2, 2007 at the east campus of the University of Electro-Communications, Tokyo. Computer Go Forum is the co-organizer. This competition, being planned as a successor of Gifu Challenge, is open to anyone in any country. The aim of the competition is, by serving as a place of technical exchange of international computer Go research, to activate research of computer Go. With this purpose, the winning prize is not money, but a trophy. Important Dates: Entry submission deadline: October 31, 2007 Championship: December 1-2, 2007 The website of the UEC Cup is as follows: http://jsb.cs.uec.ac.jp/~igo/eng/ You can register from the form provided on the website: http://jsb.cs.uec.ac.jp/~igo/eng/mailform.html If you have any questions, feel free to contact us from [EMAIL PROTECTED] ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
Re: [computer-go] .. if Monte-Carlo programs would play infinitestrong
Eeh, am I missing some point here or would not any Go program that uses search and infinite computer power simply SOLVE the game - given that scoring is done right and infinite loops are ruled out? The question should be more precisley stated as: Is playing strength a strictly-monoton increasing and unlimited function of computing power. But I thought the meaning of the question was clear. Considering simple Monte Carlo approach to 9x9 Go, the answer to this question is, No. Experiments made by Yoshimoto showed that dimishing returns could be seen when adding samples. It is described in the following article: Haruhiro Yoshimoto, Kazuki Yoshizoe, Tomoyuki Kaneko, Akihiro Kishimoto, and Kenjiro Taura: Monte Carlo Go Has a Way to Go, Twenty-First National Conference on Artificial Intelligence (AAAI-06), pages 1070-1075, 2006 The paper could be found at the following location: http://www.fun.ac.jp/~kishi/publication.html -- Shunsuke SOEDA ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
