You can have multiple kos on the board. Two is the most usual case that doesn't trigger other rules. Easiest (logically, not practically, perhaps) is to never repeat a board position ever (so called superko, I think), which could be implemented as a full-board-position hash. s. On Mar 11, 2015

Lukasz, They are not newcomers. See KGS Annual championship ranking, for example. Nomitan and DolBaram have KGS rank 3d and 5d, resp. in blitz games. #DolBaram registered last UEC Cup but didn't come to the venue :D The reason Zen lost against Nomitan was, as far as I've studied, just a

As for the game records in the UEC Cup, we are checking them manually because there are some garbage in the SGF files saved by the NNGS server. It will take several days to clear them all to publish on our Web page. Sorry. By the way, as a side information, Sakakibara kun is a 7d in Tygem. Best

Can you say anything about whether you think their approach to unsupervised learning could be applied to networks similar to those you trained? Any practical or theoretical constraints we should be aware of? On Monday, 16 March 2015, Aja Huang ajahu...@gmail.com wrote: Hello Oliver,

 The important thing is that the games don't have to be played perfectly: They just need to be significantly better than your current model, so you can tweak the model to learn from them. Thats an important incite. I hadnt thought of that.  Maybe could combine with some concept of forgetting,
