Re: Scaling of Lc0 at high Leela Ratio

Disagree here. It has been shown that given enough nodes, MCTS and minimax converge. Since alpha beta is just a faster, more efficient, version of minimax, that means alpha beta and MCTS converge too. It's therefore not correct to say that MCTS can't find mate in two. It can, it's a question only o...

Re: Lco road to 8000 or 10000! self play elo.

P.S, Testers say 30xx network is still -100 to -150 elo beyond 11248. Fake news.... anyone can verify or disprove your claims after even just a few games, I believe it's actually worse...

Re: Lco road to 8000 or 10000! self play elo.

I can show a sample of CCRL 40/40 games (easily 30s/move) between equal-rated engines (2900) with a sequence of 4 1-0 for either one. Self-play may have even higher draw rate plus probably much higher for top engines, but that doesn't change the fact that 4 games is not enough whether you like it o...

Re: Lco road to 8000 or 10000! self play elo.

No, I don't think that's realiable - this can happen quite easily (again, speaking of engines of similar strength, not hundreds of elo gap) It took me 10 seconds to find 4 games where two versions of my engine scored 3 1/2 - 1/2 in self-play, but after 10k it was a wash and within error bars. I see...

Four games, 30 sec to move
Lc0 with old NN is stronger
This is hilarious, play 1 game next time.
I wish I knew that it's sufficient to test with just a handful of games, that would've saved me tremendous amount of time.
The only hilarious thing is Lc0 self-testing.

Re: My non-OC RTX 2070 is very fast with Lc0

Just looking at NPS doesn't say anything about engine strength if you tweak the search settings. Evaluating the same position over and over is really fast but also not very useful. Do you know the true search speedup with Lc0 going from one card to two? Would 2 x 2080 Ti be about 1.8x faster than o...

Re: How good is the RTX 2080 Ti for Leela?

I have a question. I can buy a dual 2080 OC with 8gb GDDR6 each for a similar price as A single 2080 ti OC with 11GB GDDR6 Which would give the stronger Leela performance and by how much? Dual 2080 hands down. Thank you! From the spreadsheet, the rtx 2080 gives about 26000 nps and the rtx 2080 ti g...

Re: My non-OC RTX 2070 is very fast with Lc0

My power supply is not that strong (500W), hope it stays well. I think power supplies are at their most efficient at about 50% load, as they reach maximum load the efficiency drops a bit - might be finding out what wattage you're consuming with a power meter. But if your CPU is a quad, only one har...
