Hyatt 4000 openings
Hi,
Anyone knows where I could find the "Hyatt_4000_openings.epd" file mentionned on the CPW? The link there is no longer working.
Thanks.

Re: Learning piece-square table
I am not sure what the current standard way to approach this is. In Winter I only use PSTs for knight and king position evaluations. I assume the board is completely symmetric with respect to rotation and reflection, which is not actually the case due to pawns as well as castling rules. Under this ...

Learning piece-square table
Hi, I'm rewriting my (a new) chess engine from scratch and I'm about to write a basic evaluation function that would at first only consists of material and piece-square table (psqt). For now I'm not gonna do any learning I'm just gonna chooses values that seems sensibles to me, but eventually I'm go...

Can theses be used to test a chess engine?
How performant are they compared to a desktop computer?

Re: Lazy SMP in Cheng
Hi Martin, As you know I just recently found out that lazy SMP is a valid alternative to YBWC. Since then I read a it about it on CCC. The idea is that if you have, say, two threads searching a depth d you also launch two threads at depth d+1. When one of the thread searching at depth d finish it's ...

Re: A new chess engine : m8 (comming not so soon)
Isn't lazy SMP the technique that use the TT as a communication device between threads that search the same tree? Basically yes, but it has been improved since the old days (also we're using larger TTs today): resync on each ID iteration, early termination when one of the helpers finishes and run e...

Re: A new chess engine : m8 (comming not so soon)
Perhaps you may try chess variant, say capablanca, 8 rows x 10 columns. Two pieces each are added in each side, one piece is a combination of knight and rook the other piece is a combination of knight and bishop. It is fun and interesting to explore the possibilities of these two new pieces over th...

Re: A new chess engine : m8 (comming not so soon)
I'm pretty sure you meant 7. Lazy smp :wink: It scales above 16 cores and works even at ultra-fast TC (1" per game). YBWC already contradicts point 1 (lazy smp can be implemented and debugged in two weeks or perhaps even less). Isn't lazy SMP the technique that use the TT as a communication device ...
