DON Chess Engine

[erashid]

If it is stockfish based, how come you already started work on it in 2003? Stockfish was released in 2008. Glaurung 2004.

It was Initially my own implementation.
Later, when marco started.
I took some (to read: almost all) ideas from there.
But it is still not a complete fork.
You can compare code and see there is nothing same now.
you can't even compare a single file with SF.

Thanks

Stockfish is a clone/derivative of DON. We'll probably be tormented by this masterpiece this year too...

Are you seriously saying this?

I am surprised?

Thanks

The latest version really didn't impress me. It seems you messed up something:

All my engines work perfectly on SSE41, but the DOM stops working after 4 or 5 matches, it freezes. Does anyone else have this problem? As I said, only it gives me trouble...

Hello Chacal,

I already told you if you give little time and help me i will resolve your issue.
Otherwise DON engine is great .. you already see.

But I think you not have enough time to give and solve your own problem.
and you ..self assumed the engine is not working...

What else I could say.

Thanks

But I insist on asking, is the problem only with me? If so, it's simple, I don't use the engine and it's solved...
