Okay, I added a few more timings (playouts / second, very rough): Plug-and-Go refbot:        14700 CRef bot (-O3)             12500 Gongo                      1 Java bot:                   6500 CRef bot (no optimization)  5882 Note that Gongo and Plug-and-Go are using different board data

I took AMAF as the process to consider all the moves regardless when they were played in the sequence (although a slight discount for later in the sequence seems to help a little) whereas RAVE is using an undefined method to favour some nodes over others prior to expanding them. The reason (as far

The relative values look about right. But I remember getting much higher numbers. Did you run the Java versions with or without the -server parameter? Mark On Mon, Dec 14, 2009 at 11:00 PM, Brian Slesinsky br...@slesinsky.org wrote: Okay, I added a few more timings (playouts / second, very
