Can you reproduce it issuing gtp commands, i.e., loading in the failing position from sgf-file and requesting gnugo to generate a move? Example: loadsgf games/strategy25.sgf 61 gg_genmove black On Thu, Jun 18, 2015 at 3:56 PM, Petr Baudis pa...@ucw.cz wrote: Hi! I've observed the

Re: [Computer-go] fast + good RNG

Looking at the lightest playout version of my bitmap-based 9x9 program (source-code somewhere in the archives), I spent an estimated 2% of the time generating random numbers, so 40% seems to indicate something is not right, such as re-initializing the generator all the time. The execution time of

Re: [Computer-go] Teaching Deep Convolutional Neural Networks to Play Go

Correct me if I am wrong, but I believe that the CrazyStone approach of team-of-features can be cast in terms of a shallow neural network. The inputs are matched patterns on the board and other local information on atari, previous moves, ko situation, and such. Remi alluded as much on this list

All, I completed a new, improved, still not perfect, but hopefully more portable version of the bitmapgo mockup. The 9x9 source will be send out separately as a reply. I am still cleaning up the 19x19 version and send it later. Some general observations and questions: o drop-off in playout

Welcome Aldric, Not a frequent poster myself, here are two resources that you may find useful. 1) an extensive library of articles related to computer-go is collected on http://www.citeulike.org/group/5884/library This list provides a wealth of articles tracing back many years and used to be

Re: [computer-go] CUDA and GPU Performance

Christian, Would you care to provide some more detail on your implementation for the playouts? Your results are very impressive. At 19x19 Go using bit-boards, your implementation is roughly 7x as fast as the bitboard implementation I presented just a few weeks back, and also outperforms libEgo by

Zach, I can't help the windowsiness, but thanks for taking a look already. Popcounting I believe to be optimal for 32-bit only instructions, especially since I would like to keep the intermediate byte-count to help speed up the random pick function. There is a really neat trick to speed up the
