But without and *.ini and without a README, how to set different parameters/personalities?

I think the idea is that you use the Engine Settings dialog to set the parameters, and then have the GUI save them, so that each time the engine is loaded it will automatically run with the modified settings.

George, I thought Ferdinand already had answered this in the original thread about your problems?

http://talkchess.com/forum/viewtopic.php?t=62611

Ok, I think I understand now, you miss more or less a readme file for knowing what settings can be changed at all?
Ferdinand described how you can see them by starting from console and feeding a few commands to get them.

You can also load it in WB and just look at the settings.
There is a menu for this, since ... I don't know when - several years at least.



For CuteChess Ferdinand has already described how you change the engines.json file with the desired settings...

Edit: I forgot that you also directly can see and change the engine options in CuteChess under Engines/Advanced options or similar...

In WB 4.8 you can modify the winboard.ini file and the command line for this engine, for example, to change the value of pawn in op and en.

Code: Select all

-firstOptions "PawnValueOp=90,PawnValueEn=120"

In WB 4.9.xxxxxx, options can be saved permanently by going to the engine settings, modify its values and press make persistent button.

George, I thought Ferdinand already had answered this in the original thread about your problems?

I missed that, but in the general case anyone doesn't read this forum how could he set the parameters in cutechess-cli for example?

Ok, I think I understand now, you miss more or less a readme file for knowing what settings can be changed at all?

Well i see the settings inside Cutechess or Winboard and i was too dumb/fast to ask anyway.
With an *.ini file it was more convenient but anyway this works too so....

Ferdinand described how you can see them by starting from console and feeding a few commands to get them.

For CuteChess Ferdinand has already described how you change the engines.json file with the desired settings...

Thank god there is not need to do that manually.

Thanks for keeping this engine updated, still the best playing 10x8 with much new parameters.
In my tests though, previous version 3.2 remains the strongest.

Thanks for the info, I have not seriously tested it vs 3.2 before the release but tested it vs other engines. There was a bug that I unfortunately introduced in my pruning/reduction modification. I will fix this once I get the time.
