Re: Official: Lc0 is the strongest engine :)

You inspired me to run a test to see if Komodo MCTS also plays middlegames relatively stronger than endgames. Current Komodo MCTS (dev) on one thread now can beat normal Komodo 9.1 (by 31 elo in my test). I then reran the test starting with positions with the queens already exchanged. The result wa...

Re: MVL vs. Komodo handicap match

I played the six handicap games myself against Komodo MCTS under same conditions as MVL, with newest version. I drew games 2 and 6, lost the other 4. Going by the rating difference between MVL and myself, this would imply that he would win by 5 to 1, but of course the underlying assumptions are not...

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

your engine seems to attract a lot of interest. If this is not too personal question, are you by any chance super brilliant ? ... troll question, but I suppose I'll answer ... ? I don't consider myself to be brilliant, no. Knowledgeable, yes. why a troll question?, you cannot write a even a mediocr...

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...

Re: Something goes wrong with lc0 since yesterday?

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...
