Re: 7-men Syzygy attempt

These things tend to be exponential. In particular, you'd need a machine with a lot more RAM than 1TB. I thought roughly speaking you need 60 times more hard disk and ram for each extra piece. I’m sure the factor should be much smaller than 60. Long time ago someone has already predicted that build...

Re: Strange Lc0 TCEC performance

Watch a game of TCEC -- Leela best moves will match the opponents predictions for large chunks of the game. This is clearly misleading since this happens with all pairs of strong opponents. And yet after only 6 games in the bonus games between Leela 10520 and 10800 against Ethereal 10.81 with 6 dra...

Beating all humans by giving the rules and the goal of Chess and letting it self-play to "understand" what is Chess about and how to play it well, is easy? The above is of course not easy and has only been achieved in the last few months. beating humans with computers with conventional a/b software...

Re: Something goes wrong with lc0 since yesterday?

They are just demonstrating that using neural networks is inefficient. What can be wrong with that. Maybe less human work but enormous waste of electricity.
