Sorry for being late, I just saw this thread. Sure, I'll try to push this one. I think the best moment will be after Joerg's test passes or fails. In both cases, your piece values will be a good test for the SPSA sanity.Lyudmil Tsvetkov wrote:Sorry, SF guys, I just can not resist seeing Joerg pushing a piece values patch on the framework, and me not being able to do so...
I had the opportunity to suggest in the past a change for a single piece value, the pawn, but never for all pieces at the same time.
It is simply irresistible, I am sure my values are going to pass after 500 games.
Below are my suggested values:
PawnValueMg = 194, PawnValueEg = 256,
KnightValueMg = 817, KnightValueEg = 846,
BishopValueMg = 840, BishopValueEg = 865,
RookValueMg = 1278, RookValueEg = 1294,
QueenValueMg = 2514, QueenValueEg = 2547,
MidgameLimit = 15581, EndgameLimit = 3998
Lyudmil, you possibly told you could push one other patch in the future, could I ask you for the last time that we try this one, just for a single time, maybe when there are fewer tests going?
I would be very grateful, it is simply irresistible.
Or maybe someone else could help me with pushing the above patch, I am sure Joerg will not mind to have one other version tested.
BTW, I pushed the SPSA test for the rook psqt. The first time the values were too many (64+64), so I rescheduled it with only mg values and symmetric about vertical (32 values to tune).
