0.3.2

• Fixes a bug where the bot passed too early and lost won games because of it. #261
• Resign lost games earlier. This speeds up the benchmark and is also nicer for humans. #264
• Speed up the calculations of the priors by moving them into the worker threads. #275
• Implement the reg_genmove GTP command. #289
• Implement the kgs-genmove_cleanup GTP command. #290
• Improve the scoring accuracy when the game is over. #292
• Fix bug where some rotations of the small patterns were missing. #299
• Implemented the imrscl-uct_gfx custom GTP command. A GoGui analyze compatible command to show the number of playouts that went through each child node of the root (i.e. each point on the board) #293

Performance

The benchmarks were run on a c4.8xlarge EC2 instance with 8 worker threads.

After running 500 games on 9x9 with komi 6.5 and a time limit of 2 minutes (sudden death) the win rate against GnuGo 3.8 level 0 was 76.2% (± 3.71 at 95%, ± 3.79 at 99%) with the default configuration. It agreed on the final score with GnuGo in 74.09% (± 4.35 at 95%, ± 4.44 at 99%) of games.

After running 1000 games on 13x13 with komi 6.5 and a time limit of 10 minutes (sudden death) the win rate against GnuGo 3.8 level 0 was 42.8% (± 3.05 at 95%, ± 3.11 at 99%) with the default configuration. It agreed on the final score with GnuGo in 59.78% (± 4.53 at 95%, ± 4.63 at 99%) of games.
