Re: Finally, Norway found the solution to end all agreed draws

I dunno about you but I watched 4 classical games that lasted for hours and ended up drawn because the players were saving their energy for the Armageddon.

Then the Armageddon was a crapshoot especially Aronian - Grischuk.

Solution looks worse than the problem to me.

Re: armageddon in norway chess

BTW do you know, if the armageddon games count for the blitz ratings, or if they are simply discarded for blitz elo? (Or may be, if this becomes an adopted new way for future tournaments they will create a new list?) The details for URS are not published but from the high level description such a s...

Re: Why are super top professional Go players so stupid?

I thought that setting komi (KM) in the SGF file is enough to make Leela play with desired komi. Wrong! Leela engine doesn't support komi setting, it is designed with fixed komi 7.5 and no handicap. Not only that, all the networks are trained to play well only with this komi of 7.5 and no handicap....

Re: Why are super top professional Go players so stupid?

I am pretty amazed having this thing on my PC as free open source software, that's why I posted here. These human players I am writing here about are Gods, and my stupid irreverencies please me :lol: . The most amazing thing IMHO is that in chess, we had ~15 years or so to get used to computers gra...

Re: Why are super top professional Go players so stupid?

If they use only OpenCL and not CUDA (cuDNN) that's really... unclever. :lol: :lol: :lol: :lol: :lol: I believe Ttl/Henrik Forsten has a CUDA+cuDNN version in one of his github branches. AFAIK it is slower or at least the performance difference was completely uninteresting. On RTX cards the OpenCL ...

Re: Question to Remi about CrazyZero

If I understand correctly, Leela Zero and Leela Chess Zero have become a fork. They would probably have made faster progress together if they had kept the same code for both games. Most definitely. There's several things implemented in one engine that aren't implement in the other, both ways. Forki...

Re: Wouldn't it be nice if C++ GPU

Writing my own cuda is certainly not a reasonable choice, but it is fun to try, and I still believe it is possible to outperform cuDNN for small batches. You don't need to guess. lc0 got a commit recently where the contributor who also works on NVIDIA's drivers added a hand-written CUDA kernel for ...

Re: Alphazero news

Matthew, I have one last question regarding the implementation details that aren't explicit in the paper. Normally, an MCTS search would do "tree reuse" from move to move, carrying forward the subtree that was actually chosen. But during the training, there is noise added to the root. If one does tr...

Re: CB15 bug

A small bug I notice is that it keeps deleting the .ico file of my database when I update the games.

Re: Alphazero news

Were other settings ever considered, notably 0.5 or parent? Yes and 0 seems to work best. Assumption being that most positions have 1 or at most a few good moves. All other moves are akin to passing or worse. In most equal-ish positions, passing will give the opponent a big advantage. I think this ...
