I'm sure the engine author can help you with this.

We will just leave that as it is as I am looking for something that the strength can be increased by optimizing eval param values. For personalities, this is already the intended behaviour of the engine, so we will not touch it.

I am looking for uci engines that have more options especially evaluation parameters, options that are of spin type, example.

option name PawnStructure Bonus type spin default 30 min 0 max 99

I will try to optimize these engines as an experiment with my tuner.

I knew MadChess, and Amyan.

Hello !

The recommendation of Ruxy GmBH AG (the no.1 in area, by far ) is:

DisasterArea of Herr Jochen Peussner/Germany !

The evaluation (and what an evaluation ! Its ancestor was famous: the private Neurologic) is completely tunable.

Development versions of iCE allow the modification of all evaluation weights at runtime. But I dont use a UCI option for that as I don't intend to expose those parameters in a GUI.

There is a special setweight command in iCE that changes the weight

Code: Select all

Usage: setweight name <name> values <mg eg> [-q]
       setweight id <id> values <mg eg> [-q]
       setweight default

     |                                           |    WEIGHT    |
  ID | WEIGHT NAME                               |   MG     EG  |   MAX
 ----+-------------------------------------------+--------------+-------
   0 | PAWN_MATERIAL                             |   101    113 |    127
   1 | KING_MATERIAL                             |   INF    INF | 32.767
 ----+-------------------------------------------+--------------+-------
   2 | KNIGHT_MATERIAL                   MIN 300 |   407    405 |    555
   3 | BISHOP_MATERIAL                   MIN 300 |   407    432 |    555

setweight id 0 values 105 105
Setting weight PAWN_MATERIAL [ 0] values to (105, 105)

If you are interested I can make you a dev version of iCE 2. All those weights are tuned by my GA tuner so I use some partly strange looking values that work somehow but are probably far from optimal.

If you are interested I can make you a dev version of iCE 2. All those weights are tuned by my GA tuner so I use some partly strange looking values that work somehow but are probably far from optimal.

At this time I am only interested on uci option type formats, as the tuner is adapted on that format, although I can change the tool to use setweight.

My tuner is a script, and after determining some values, I use cutechess-cli and set options there for game test.

I see that this is problematic when testing large number of params, reading from a file would be a better option.

I am not into large params tuning yet, just a couple of 10 to 20 params so far.
