Re: LCZero Accomplishments and Goals Thus Far

Sigh..wake me up when it is 2800 elo running on singe CPU core, which is what every other engine uses in rating lists. As far as I am concerned, it is still a 2100 elo engine there. Your demand for uniform platform comparison is commutative. Why not demand all the other engines run on a GPU? Then i...

Re: LC0 on 43 cores had a ~2700 CCRL ELO performance.

A0 was not better than SF8 even with 4TPUs. Rigged tests and and cherry picked results mean nothing. Deepmind paper states that out from 1300 games A0 played with Stockfish the result was +318 =958 -24 in favor of A0 so how A0 is not much much better than SF?? Do you accuse Deepmind, a research com...

Re: LC0 - how to catch up?

Stunning progress in the last weeks, maybe it is a bit too early, but i believe here is an paradigm shift underway. So how do the old school chess programmers intend to catch up with LC0? -- Srdja I do not see a progress in the last weeks but a regression. This is normal. AlphaGo and AlphaZero also...

Re: LCZero: Progress and Scaling. Relation to CCRL Elo

On tactical test suite, also no significant progress. Let's hope for now that move selection in the openings will change this real stalling (that in self-games was artificial). It surely was stuck with some local optima in the openings, and the whole training process was flawed. If not this is the ...

Re: LCZero: Progress and Scaling. Relation to CCRL Elo

Indeed. Leela's output is an expected score, not actually a win%. The wording on the site has since been changed, it seems, although now it includes this "50%=draw" bit in the legend, which caused some debate in the discord. Probably should just say "50%=equal chances" or some such thing ("expected...

Re: I'm not very happy with the do {} while() statement in C

saddling the development community with a scrawny architecture basically forever. Well, no. The last true x86 architecture was the 486. After that, we still have the external x86 instruction set, but not the architecture; internally, modern x86 CPUs are something entirely different. And nobody care...

Re: I'm not very happy with the do {} while() statement in C

It is simply what you get when you keep hacking on an instruction set to add new features. The customers have decided that they don't want to throw away all the software they already paid for. That's why backwards compatibility won, because it addressed the needs of the paying customers. But none o...

Re: Google's AlphaGo team has been working on chess

It's still sold. BrainMaker Professional for Windows $795 :lol: CALSCI had a second generation of ISA/PCI accelerator boards that could process 2.3B NN connections per second (a Pentium 90 could do 1.9M connections per second). These boards shipped with either 64 or 128 CPUs and cost up to $8,345. ...
