Re: trying to understand mcts

Zeta v097 and v098 were an attempt to make use of thousands of parallel gpu- threads via an parallel Best-First-MiniMax search and classic evaluation. Very interesting, thanks. When using large neural networks, evaluation is so slow that data transfers between CPU and GPU have very little cost. GPU...

Re: Search speed

Can anyone write the code that would use to search in the processor AMD - L1 cache size and L2 cache size. I mean it would be the best and greatest search in kN/s Fundamentally, I think that kN/s is the wrong metric. "Practical" is about "Time to Depth" (searching ply 10 faster). Even then, maybe t...

Re: Is e4 significantly better than d4?

How can one refute the entire d4 tree? I think that when we will be able to do that, we will be close to be able to show weakly that Chess is a draw. Fair point. I need to work on the precision of my words a bit... I think that what I'm trying to say is that a degree of minimax should be applied to...

Re: Is e4 significantly better than d4?

I am still into silly things. An I still think Lc0 bignet on my RTX 2070 is stronger positionally than any human. I understand the arguments against, and they are very solid, but I will stick to silly approaches. I took the KingBase, selected the games of FIDE Elo 2700+ both players, and played gam...

Re: Threadripper Custom Build - feedback wanted

Lc0 uses tablebases just fine. Interesting. How does the neural net factor into the tablebase? Or is it only the (relatively slow) MCTS portion that uses tablebases? LC0 only searches in the ~100,000 nodes/second speed. So they won't be probing the endgame table as much as other engines (which are ...

Re: Threadripper Custom Build - feedback wanted

It sounds like a lot of fun. What are you going to do with it? With an Alpha Beta engine there are questions about its ability to use 32 cores. Do NNs use 32 cores? What about getting a 16 core using Hyper threading and save some money. Threadrippers come with 64x PCIe lanes, so you can run 4x GPUs...

Re: Threadripper Custom Build - feedback wanted

Actually, consider the x399 Taichi motherboard: https://www.asrock.com/mb/AMD/X399%20Taichi/index.asp It has 2x 1Gbps Ethernet NICs + Intel 802.11ac WiFi built into the motherboard already. The main issue with the Taichi is that it needs 2x 4-pin power connectors (which is a bit unusual). ----------...

Re: Threadripper Custom Build - feedback wanted

Storage: Intel 660p Series 2.048 TB M.2-2280 NVME Solid State Drive $184.99 That's QLC (4-bits per cell), are you cool with that? I'd rather go with TLC (3-bits per cell), which is better tested. QLC is new tech, so we really don't have good numbers on the long-term reliability of that. It is a goo...
