[computer-go] published stats on string merge frequencies, etc

2009-04-29 Thread Christian Nentwich
Hi all, I've been looking through the archives trying to find out if anybody had published information on the following during uniform random playouts and/or real games: - Frequency of string merges - Frequency of placing stones in empty space - Average length of strings, etc. I noticed

Hi Yamato, Could you give us the source code which you used? Your algorithm is too complicated, so it would be very helpful if possible. Actually I think the source code would be much harder to understand! It is written inside RLGO, and makes use of a substantial existing framework that

Hi Remi, What komi did you use for 5x5 and 6x6 ? I used 7.5 komi for both board sizes. I find it strange that you get only 70 Elo points from supervised learning over uniform random. Don't you have any feature for atari extension ? This one alone should improve strength immensely (extend
