Looking for uci engines with piece value options shown

[Ferdy]

I will be testing/improving an spsa tuner at https://github.com/fsmosca/spsa. I am primarily interested on uci engines with settable piece values. Deuterium has and I am looking for others to try. What I will do is to weaken the engine by unoptimizing its piece value and try the tuner if it can improve from there.

If you try it, and have some available threads, just increase the number of rounds in cutechess-cli setting or read this section https://github.com/fsmosca/spsa#c-sampl ... n-scenario.

While it doesn't allow to set up piece values, Stockfish derivative Thothfish allows you to modify them:

Some free Rybkas IIRC had it.

I'd be glad to release a Minic version for that if you're interesting

option name Queen OP type spin default 0 min -100 max 100

Can't use this at the moment because there is space in the option name. Will revise the tuner later to accept parameter name with space.

Does Queen OP value mean an increment/decrement to a default value?

Not in 2.3.2a so far.

I am interested, preferably an option name without space. Also allow the min/max to have more distance from default value.

Example:
option name KnightValue type spin default 300 min 100 max 500

The King and other old versions of Chessmaster from CM9000 up to the last version I think.

You can use Minic 2.38 unofficial release. All pieces can go from 0 to 2000.

If that work, please send me your optimized setting !

In Cheese you can change pieces values but only in personality files.
I could add an option in the next version but I have no time to release a new version before September.
