Re: [computer-go] Minimax with random evaluations

And I'm running it now.  I implemented it the slow naive way, generating
a set of legal moves twice, once for each side.

I'm pretty sure this is equivalent to simply counting single point eyes.

I don't have enough games to give the full picture but after a few
minutes the legal move count version is easily dominating both the
random evaluation and the random mover.


LMC(5) = Legal Move Count at 5 ply
RE(5)  = Random Evaluation at 5 ply
RM     = Play a random legal move.

  LMC(5)  vs  RM     97.4%  (38 games)
  LMC(5)  vs  RE(5)  87.1%  (31 games)

   Ok, I will put on a legal-move-count evaluation test to see what
   happens.

   But even if it scores well, it doesn't necessarily follow that it is
   because it's mimicking mobility.  My intuition however is that it
   basically does.  

   Speaking of intuition, I couldn't agree more with you.  I have learned
   NOT to trust my intution.  Intuition is very useful for many things,
   but not for drawing hard conclusions.
