[computer-go] More UCT / Monte-Carlo questions (Effect of rave)

[Chaslot G (MICC)]

I also implemented RAVE in Mango. There was a few points of improvements (around 60 Elo points with gnugo as reference), but as much as in the paper of Gelly and Silver :( (around 250 Elo points if I remember well)

It might be that the effect of RAVE depends a lot on the simulation strategy. Indeed, sometimes my RAVE was playing very good moves but also very bad ones.

I get a small effect from RAVE, My rationalisation is that if the  
program is rich with other features to improve performance RAVE may  
not add that much.
