Re: ChessBase's prophecy of 2004 fulfilled in 2019

Rank Name Elo +/- Games Score Draws 1 Kimo 42580 49 30 400 57.0% 24.0% 2 Kimo 11248 18 30 400 52.6% 23.8% 3 Texel Elo 2100 3 32 400 50.5% 14.5% So with no search, NN 42580 is only about 30 elo stronger than 11248. From what I've seen, I'd be surprised if old NNs are much above 2000 elo on a human l...

Re: Neural Net Endgame technique

One thing missing from the discussions are actual examples of endgames being 'solved' by a neural net so people just assume Leela's endgame weaknesses are a neural net feature. I hope to rectify this in this post and hopefully any future discussions might take these examples into consideration. (I'...

Re: Where are the funs of Leela?

A lot of tests were around 1 min bullet. But there were also 3+2 min in 2080RTX and also a few people with 20xx RTX cards do exact TCEC time control with 2 hours per game. I wonder if there are any updated scaling graphs. For older versions, there looked like a problem with Leela's scaling, especia...

Re: Where are the funs of Leela?

Not sure. It points to Lc0 being much better than SF in the openings. About the weights of openings and middlegames, I had some results showing middlegames as more important. After all, the result starting from the middlegames is only +7 -3 and a bazillion of draws for BF, not an outrage, not even ...

Re: Where are the funs of Leela?

I had a look now too. You have to be aware of the conditions. Right now they are playing starting from the move 22 (!) of some important game of the past. So, right from the middlegame, completely missing the opening and early midgame. So again it points to the opening having a disproportionately l...

Re: Where are the funs of Leela?

In Leela discord , before Sufi 14 and Sufi 15, there were extensive amounts of games tested with exact SF vs Leela ratio in Tcec, around 5000 to 10, 000 games before s14 and 20,000+ games before S15. Those tests must have used much smaller nodes per move, though, if there were so many games. That w...

Re: Playing the endgame like a boss !!

EGT info is a direct result of the rules and nothing but the rules. That doesn't mean it's an obvious result or a result obtained quickly, easily or without any thinking. And it doesn't mean Leela can just use those results and pretend it's zero. It isn't. Are you claiming that when humans generate...

Re: Playing the endgame like a boss !!

So Alpha & Leela Zero are NOT zero at all. They would only be if they had worked out themselves that it would be a good idea to do tree search, then worked out themselves how to do it, and then went ahead and did the PUCT search for themselves, rather than just playing the move the NN's policy head...

Re: Playing the endgame like a boss !!

Where is this misconception coming from that EGT would be a non-zero technique? It uses nothing but the rules and the winning condition. If it worked out itself that it would be a good idea to do retrograde search, then worked out itself how to do it, and then went ahead and did the retrograde sear...

Re: Playing the endgame like a boss !!

Why would this be non-zero? Similar things have been discussed about AlphaGo. We won't know either way until we know exactly what it is doing. But if a non-zero feature was "discussed about AlphaGo", that wouldn't make that feature "zero"; it would make AlphaGo non-zero. (Lc is already non-zero bec...
