Re: Syzygy DTZ data explaination?

Fathom ranks (and scores) all winning moves the same unless the probe code indicates the position has been repeated (i.e. that the engine is failing to make progress by itself). Thanks! After telling the position is repeated, the data looks more reasonable. It could explain why Rc2 and Rg6 (by rank...

Syzygy DTZ data explaination?

I used to work with Syzygy WDL and everything is fine. The results of W/D/L are easy to understand. However, when looking into DTZ data I am so confused since the data is not self-explanation to me. The result only (winning line) is not enough for me since I have been working on a studying tool to w...

Re: Leela Output

Allow me to add an extra question (perhaps it is answered somewhere but I cannot find out). Can someone explain what N, P, Q, D, U, V are in lc0's move stats. What is the first number (e.g. 230 right after the move b2b3)? What is the condition for a move to be the best one? Thanks. info string b2b3 ...

Re: Some newbie questions about lc0

Thanks for replies and info. Bitboards are fed to the net sort of like images and the net outputs preferred moves and such. Got it! According to Chessprogramming (CPW), lc0 uses 5 bitboards, equal 5 x 8 = 40 bytes. Thus the input of lc0 is at least those 40 bytes, is it correct? If I use a mailbox b...

Some newbie questions about lc0

I’m new to lc0: just downloaded, took a look, read around, compiled it for my iMac then run training/contributing for a while. My purpose is to learn for fun then check possibilities to add some chess variants to lc0. I think it’s better to ask some (probably silly) questions here before diving deep...

Re: Congrats the Komodo Team

And maybe the biggest share of the success goes to 8 x Intel (R) Xeon(R) Platinum 8168 CPU @ 2.7 GHz, 128 cores used. :wink: Can someone give me an estimate about the price of that computer? Thanks Well, each CPU is about $6000 (6000 USD). :D Amazing expensiveness!!! So the price of Komodo computer...
