New engine _Crab_ based on StockFish

[smatovic]

unbelievable but not impossible...

gets around 2700kN/s so it's as fast as the JA build

no i am debugging this code for hours seems that i messed up my equations some where....

Has Jim made a compiled exe for this engine? Or are you referring to Stockfish?

compared to stockfish

Oh Ok, I hope that Jim makes a compile for this one too!

[Look]

You know Sven Berger, maybe some StockFish/Crab code has gotten in your simulation project, watch out!

Many thanks for the new compile, but I can't seem to get reproducible results comparing both the 32-bit build and the 64-bit one. Times, solutions, you name it, are different. Meaning, they act like different engines.

[Look]

So Silver, are you suggesting that, Berger has added some of his simulation code to Crab to revenge ?

[svchbe]

it's the same story with the stockfish builds...
so it's probably some kind of optimization...

Yes, it is a plot.

Seriously though, I get solutions at different depths, almost randomly, on every position, the plycount varies, etc. I don't know if this is normal, but it makes comparing them, without extensive testing, difficult.

Maybe it's nearly an original program and not entirely based on Stockfish.

It could be categorized as engines akin to Protector 1.3.5 which I think was considered original rather than derivative.
