RE: [computer-go] Passing and RAVE/AMAF

[David Fotland]

I use Many Faces' knowledge.  If the Many Faces engine says the game is in
endgame and there are no dame left, then pass is enabled in that node of the
UCT search.  The game is in endgame if enough moves have been played, and
all groups are settled (either alive or dead).

 The question is, what about passing? That presumably doesn't get
 counted as a good future move in AMAF, so how can passing gain wins
 (or runs, for that matter) when it's the right move (e.g., when there
 is a seki on the board)?

Yup, I can verify that my half-baked plan didn't work. If you use  
most wins to choose moves during playouts, once you have a win, you  
will never change your mind, because each playout will either  
increment that move (and maybe some others) or increment nothing  
(because it's a losing playout).


So: Pebbles only for actual moves, not playout moves.

The Pebbles rule (I should have published something better than this
first, so that 'Pebbles Rule' could refer to something really cool)
concerns solely the question of which move to select when your
search is over. The conventional choice is to play the move that has
the most *trials*, and Pebbles version is to play the move that has
the most *wins*.
