Re: Hyatt 4000 openings

Some of them are very polar, if you are going to use them for contests. Here are those with a centipawn eval of at least 100 centipawns: rn2kbnr/pp3p1p/3p4/4p1p1/4P3/5Q2/PPP1NP1q/RNB1K1R1 w Qkq - acd 36; acs 218; bm Nbc3; cce 376; ce 570; id "Hyatt-Quiet.3397"; pm Nbc3; pv Nbc3 Nd7 Nd5 Ngf6 Nxf6+ Nx...

Re: Smoothing SF progress of nextchessmove

I'm paid pretty well, but a graph of my salary over time won't look like the SF Elo graph. Mine would look more like a square root function, where it rapidly rose after college for a few years then rose more and more slowly. I do agree that even 0.05% interest growth per year would be exponential. B...

Long algebraic is what the UCI format calls it.

Handy for computers but ugly, ugly, ugly.
SAN is so much easier to read for humans.

Re: Smoothing SF progress of nextchessmove

I guess that even with the bad version the correlation coefficient is very close to 1, which means the progression is very nearly linear. Since Elo is exponential, this is excellent evidence of constantly having exponential progress in the strength of Stockfish. That is really pretty amazing. Too ba...

Re: 237 Mn/s for Stockfish on an 2xEPYC 7742

There was an analysis in the programming forum a while back that showed software advance in strength is exponential, just like the hardware advance.

Re: Trying to understand Retrograde analysis (EGTB generation)

https://www.chessprogramming.org/Retrograde_Analysis http://home.hccnet.nl/h.g.muller/EGT7/7-men.html A word on this: It is fun and interesting to examine and code an algorithm for EGTB, but there are a lot of implementations available already. If you want to do it for your own enjoyment, there is n...

Re: RMO - Randomized Move Order - yet another Lazy SMP derivate

Doesn't this indicate that the reductions are flawed? Otherwise, where does the Elo increase come from? If a fatter tree is better then maybe the reductions are incorrect or too extreme. On the other hand, it seems possible that the small extra randomness introduced by the thread local storage might...

Re: Elo - elo - ELO

Elo is Correct. ELO and elo are ignorance.
That having been said, I've probably made both mistakes.
It's like degrees Celsius. Would you write CELCIUS or celcius?
