[Bug-gnubg] Hint only uses 0-ply when importing / setting positions

[Henrik Ravn]

Hi there!

 

GNU BG seems to be using 0-ply hints when you set positions up manually.

Steps to reproduce:

 

(Using GNU BG for Windows 030501)

 

1. Start GNUBG

2. Confirm that evaluation parameters are set to at least world class

3. select Edit->Enter command and enter "set matchid cInqADAAIAAA" (w/o quotes, of course), and click OK

4. select Edit->Enter command and enter "set board 4LsLgArgOTjAUQ" and click OK

5. Select Analyse->Hint

 

This is what I get:

 

    1. Cubeful 0-ply    bar/23 21/16*                MWC:  56,66%
       0,483 0,094 0,003 - 0,517 0,176 0,007
        0-ply cubeful [expert]
    2. Cubeful 0-ply    bar/20 6/4*                  MWC:  54,68% ( -1,98%)
       0,458 0,081 0,002 - 0,542 0,234 0,012
        0-ply cubeful [expert]

.. etc ...

 

This in spite of Evaluation parameters are clearly set to world class (and so should be using 2ply)

 

I have also confirmed this with SGF position import, and by giving the commands directly to the cmdline program.

 

When I play against GNUBG a select a hint during play, it uses 2-ply, just as it should. Even weirder, if I do an Analyse->Evaluate, it correctly uses 2-ply. Still weirder, if I start a new game, and let the eval engine run at least once (i.e takea hint or let GNUBG play a move) and THEN do steps 3 to 5 I get a 2-ply hint, but ONLY in the GUI version. Starting a new game in the cmdline version and then doing 3-5 still produces a 0-ply hint.

 

What am I doing wrong here?

 

be well
