Re: Allie is very attractive

The original lc0 and Komodo 13 also play Ke2 here. As does Stoofvlees.

Doesn't seem hard to find.

Re: Will TCEC need to rewrite their rules?

Tablebases (and the associated access code) are considered an exception for very practical reasons. If using the third-party access code wasn't allowed, then every author who wanted to use EGTB would have to invent their own format (as Syzygy for example has no formal specification that you could pr...

Re: Some speed tests with Leela and Allie

Why you think that in the case of given Net and given binary there is no any connection between speed and the chess power? Because the speed changes if you change the cache size (reason, see previous post). (There's still a positive correlation in the general case, but you can come up with patholog...

Re: My failed attempt to change TCEC NN clone rules

the poster child of boom bust AI investment development cycle. Each boom has been accompanied propaganda-wise on dreams of “well if they can beat humans in chess ...” and each bust on failure to actually deliver on the dreams. So, I would posit, computer chess is about bullshit also. Extracting cop...

Re: My failed attempt to change TCEC NN clone rules

So if it was a coding competition I guess Ankan wins if either Lc0 or Allie win? Yep. (Which underlines that TCEC can't possibly be that - he's playing against himself) Or maybe *you* should get some credit if either win? Even better: I'll win TCEC if either lc0, Allie, Stockfish or Stoofvlees wins...

Re: Back To The Beginning

I have plans to build a new Intel box pretty soon, it seems that Intel will have a very big price cut on their new HEDT CPU's (Cascade Lake X) next month. If this is really true and they will sell the new 28 core for a price of about $1700 I will certainly buy one. I've been thinking about AMD, but...

Re: Some speed tests with Leela and Allie

Node speeds reported by lc0 based engines are nonsense because cache hits are counted as full nodes. Likewise, the reported depth for MCTS-based engines is arbitrary.

You can't conclude anything from these numbers.

Re: My failed attempt to change TCEC NN clone rules

So for the record, you agree that the lc0 cuDNN/CUDA backend is a very critical part to the strength of an NN-engine? I think I've been very clear and said *numerous times* that the cudann backend is a very important critical piece of code...But to be very clear, the sentiment I was relating above ...

Re: My failed attempt to change TCEC NN clone rules

The pieces were all there, Deep Mind put them all together and threw massive resources at it, but it wasn’t technically groundbreaking. When I say “A0 network types,” I mean the old familiar ResNet with chess state inputs and policy and value outputs. Nothing earthshaking about that, and value and ...

Re: My failed attempt to change TCEC NN clone rules

one of the top Leela devs told me Ankan is the most important person in the project and although he spent little time contributing, his code is really critical as noone else knows to code for GPU, and without him cuda backend wouldn't probably happen . So for the record, you agree that the lc0 cuDN...
