Re: Can somebody explain what makes Leela as strong as Komodo?

Is it the Hardware speed or some breakthrough programming innovation? So far what is the score between Komodo and Leela ? https://www.youtube.com/watch?v=ymDA7-hdkKA My answer is a bit different than others. Leela (following AlphaZero) has found a way to use a powerful GPU for chess, which is itsel...

Re: Can somebody explain what makes Leela as strong as Komodo?

My answer is a bit different than others. Leela (following AlphaZero) has found a way to use a powerful GPU for chess, which is itself composed of hundreds or even thousands of cores. So far the only method that has made use of the GPU for chess is Neural Network. If we (Komodo or any other non-NN ...

Re: Can somebody explain what makes Leela as strong as Komodo?

There are two parts to leela or other neural network based engines: search and evaluation. Leela (and many go programs) use a form of search called mcts, or Monte Carlo tree search (See UCT). It’s fundamentally different from the minimax search in an engine like stockfish. It uses a strategy (in it...

Re: Can somebody explain what makes Leela as strong as Komodo?

... How does Leela work - it plays scores of millions of games with itself and analyze the moves , the position, and the result of those games to come up with a predictive analytic outcome for each position. It takes the the position that has the highest chance of winning the game based on its hist...

Re: Lc0 with latest test30 nets is vastly superior positionally

... I used the suite five times, to have a more reliable picture, and the results are (5 x 200 = 1000 positions) Lc0 v20.1 ID32458: 712/1000 Houdini 6.03: 558/1000 Komodo 12.3: 556/1000 Stockfish 10: 524/1000 Ethereal 11.0: 457/1000 The standard deviation of the result seems to be about 15, so Houd...

Re: Dramatic drop in performance with LC0 after updating Cuda drivers

The .dll files enclosed to Leela are for Windows 10 64bits. If one uses Windows 7 64bits system that one is forced to mine out the .dll files from CUDA.exe for Windows 7 and from the cudnn-10.0-windows7...zip file. No. Why no? Maybe Leela works with the enclosed .dll files on Windows 7 64 bits too ...

Re: Dramatic drop in performance with LC0 after updating Cuda drivers

I think there is some confusion. The 'cudart64_100.dll, cublas64_100.dll, cudnn64_7.dll' files is not part of driver - they are cuda runtime/cublas/cudnn library files. Very early builds of lc0 didn't come with them, so they had to be downloaded separately from nvidia's website (first two are part ...

Re: Dramatic drop in performance with LC0 after updating Cuda drivers

Actually I did download what was the latest Cuda drivers from Nvidia … I think it was version 10. But somehow installing those drivers installed like 8 different subsets of drivers, including Physix (or something like that) and a bunch of other stuff that I have no clue what they were. Most likely ...
