Polyglot question.

[Rebel]

I am using: PolyGlot 1.4.30b by Fabien Letouzey with the ini-file

Code: Select all

[PolyGlot]

EngineDir = C:\mea
EngineCommand = fruit21.exe

[Engine]

option name History Threshold type spin default 15 min 0 max 100
option name King Safety type spin default 15 min 0 max 400
option name Passed Pawns type spin default 15 min 0 max 400

Trying to see if those changes work by crippling Fruit's playing strength considerable but it plays as strong as ever.

Next try:

Code: Select all

[PolyGlot]

EngineDir = C:\mea
EngineCommand = fruit21.exe

[Engine]

setoption name History Threshold value 15
setoption name King Safety value 15
setoption name Passed Pawns value 15

Same result, no change.

Tried to find other Polyglot versions on the net but wasn't successful.

What solution?

Your [Engine] section is in the wrong format.

Try this after the line containing [Engine]

Code: Select all

 History = 15
 King Safety = 15
 Passed Pawns = 15

The latest one from 2016 is 2.03 which is still available at HGMs site:

Anyhow your syntax for the engine section is wrong.
For your example it should be:
(I suggest adding a log too in the polyglot section at least until
you have figured out, if all your changes are really sent)

Code: Select all

[PolyGlot]

Log=true
LogFile=blabla.log

Code: Select all

[Engine]

History Threshold = 15
King Safety = 15
Passed Pawns = 15

BTW I suggest to fiddle around with 'Piece Activity' for crippling its strength.

How did you get the square brackets to appear in your "code" section?
What did you use to escape them.
I was unable to include [Engine] in the code section in my earlier post.

Colin, I did nothing special. This means either we have a different setting
in our phpbb user profile or we both have a different encoding in our browsers
and yours hits one of those mysterious encoding problems, which exist
in this board for quite a while - already before the transition)

It was that simple. Thanks.
