For my fast/dumb neural net engine, Antbot9x9, I coevolved the weights using a similar tournament system. Each individual played a number of games against all the others, round robin, and the score was the sum of points for all of its games.
Some observations/claims: Non-transitive effects seem more visible. Consistently overplaying garners extra points from weak opponents but needlessly loses extra points against strong ones. It becomes more important to play your opponent as well as the board: if you think that you have him outmatched, take some risky gambles, overplay. Every game in the tournament matters, right till the end of that game. I think it could be interesting to try some bot tournaments like this. It might be fun to watch. When the strongest bot was playing the weakest, even near the (painfully one-sided) end of the game there would be an element of suspense. The stronger bot would (or should) be trying to swindle a few last extra points it didn't deserve, and the fate of the tournament could hinge on it. - Dave Hillis -----Original Message----- From: "Ingo Althöfer" <3-hirn-ver...@gmx.de> To: computer-go@computer-go.org Sent: Mon, Nov 23, 2009 4:10 am Subject: [computer-go] Re: Hahn system tournament and MC bots Alain Baeckeroot wrote: A Go tounrmaent with Hahn system has been retransmeted see ... http://www.suomigo.net/wiki/HahnSystem Thanks for the interesting stuff and the links. >From the link HahnSystem: Winning By 0.5-10 gets 60 points Winning by 10.5-20 gets 70 points Winning by 20.5-30 gets 80 points Winning by 30.5-40 gets 90 points Winning by >40.5 gets 100 points Losing by 0.5-10 gets 40 points Losing by 10.5-20 gets 30 points Losing by 20.5-30 gets 20 points Losing by 30.5-40 gets 10 points Losing by >40.5 gets 0 point I would have found a "completely continuous result system" ore natural, for instance iving +40.5 points for each win with 40.5 or more iving -40.5 points for each loss with 40.5 or more iving x points for each score in between +40.5 and -40.5 And I believe that MC-bots would gain about 2 rating levels gainst human players, when compared with normal chinese scoring. Just my 40.5 cent, Ingo. -- reisknaller: GMX DSL Flatrate für nur 16,99 Euro/mtl.! ttp://portal.gmx.net/de/go/dsl02 ______________________________________________ omputer-go mailing list omputer...@computer-go.org ttp://www.computer-go.org/mailman/listinfo/computer-go/
