[computer-go] random evaluation results

[Don Dailey <drd@xxxxxxx>]

I ran several games with random evaluation and have some results to
report.

boardsize:   5
     komi:   0.5
       ko:   simple
game over:   after 2 passes (but not inside search)
     eval:   #define EVAL (8192 - (rand() & 0x3fff))
  scoring:   chinese (tromp/taylor) - no dead stone resolving.

 r2    44.300   1000 games
 r3    62.200   1000 games
 r4    68.800   1000 games
 r5    73.000   1000 games
 r6    92.200   1000 games
 r7    38.616    549 games


r2 is a 2 ply search, r3 is 3 ply etc.  All players are playing
against r1 which is a 1 ply search which is the equivalent of simply
playing a random legal move.

I have no clue about what's going on at depth 7.   I cannot find a bug
that would explain this.
