[Bug-gnubg] How to set up world class evaluation in command line interface?

[Kari Uusitalo]

Hi,

I am new to the GnuBG and having the following problem:

I can succesfully set the evalution in the GUI version of GnuBG
(Windows) to utilize 2-ply evalutions (in hints). However, when I try
to do it in command line interface the GnuBG does the evaluation only
to 1-ply level.

`eval' and `hint' will use:
   Chequer play:
     Neural net evaluation:
       2-ply evaluation.
       Using pruning neural nets.        Cubeful evaluations.
       Noiseless evaluations (deterministic noise).

   Move filters:
     Move filter for 1 ply:
       keep the first 8 0-ply moves
     Move filter for 2 ply:
       keep the first 2 0-ply moves and up to 3 more moves within equity 0.1
       keep the first 0 1-ply moves
     Move filter for 3 ply:
       keep the first 16 0-ply moves
       keep the first 4 1-ply moves
       keep the first 0 2-ply moves
     Move filter for 4 ply:
       keep the first 8 0-ply moves
       keep the first 0 1-ply moves
       keep the first 2 2-ply moves and up to 3 more moves within equity 0.1
       keep the first 0 3-ply moves

   Cube decisions:
     Neural net evaluation:
       0-ply evaluation.
       Using pruning neural nets.        Cubeful evaluations.
       Noiseless evaluations (deterministic noise).

In the GUI the hint dialog gives several moves that have been
evaluated in 2-ply level. So, what I am doing wrong in the command
line interface? Is there a way to somehow enable the predefined
evaluation settings (world class, etc) in the command line interface
(as there is with the GUI version)?

Thank you very much for any info!
