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

OK, something seems off. Why are the 2080 depth 17 nodes so many more than the depth 19 with the 2070? Maybe I am missing something. Thanks. Probably different nets used. But the speed should be fairly uniform with the latter test30 nets, so nps are probably fair to compare. I used 11250, which I h...

Re: Alphazero news

I do not apply my human imagination in order to explain the training process, I see it only tries to fit the output of a 800 node search by 1 node, and do so in many iterations. If you ask how that correlates to chess or any other games, then there is a easy way out, they are domain knowledge. Now ...

Re: Alphazero news

You are missing the point. The development on a basis of winning chances has led to a very different basis for making decisions with far-reaching consequences. If I understand your concept of "very different basis for making decisions with far-reaching consequences" correctly, are you referring to ...

Re: Alphazero news

it has developed on a concept of winning chances Concept of winning chances is just as lame as concept of centipawns. Given a mate-in-X position if it says anything else than 100% then it is wrong, if it says 100% then it will screw up your search. It have its roots in image recognition NNs, which ...

Re: Alphazero news

Yet, that is what AlphaZero has done, and we are even able to bring this to the home user's PC thanks to Deep Mind's generosity with their knowledge, as well as the fantatsic Leela Chess community efforts. In other words that is not limited to some absurdly exotic hardware no one could ever hope to...

Re: Alphazero news

I think it goes deeper than that. If someone, even someone whose knowledge and technical savvy you deeply respected, had told you a few years ago that they could get a program that was nearly one thousand times slower in NPS to compete and even beat the best of the day on a PC, I am guessing you wo...

Re: Alphazero news

Brute-forcing of those 28 million parameters of a evaluation function in a black-box style is neither efficient nor intelligent. Brute forcing? I think you are confusing it with your Stockfish box running on 384 threads. For generic algorithm, yes, a lazy man's solution to everything, but in chess ...
