If a ratio of 0.05 bytes/NULP is assumed, then the whole set of 8-man EGTB would be circa 1.7 PiB in size, way below 10 to 20 PiB mentioned above if my fast math is not wrong.
You need more storage to make the tablebases than you do to store the finished product.

Re: When will 8 piece tablebase be ready?

It might be "easy" in the sense that the code (more or less) exists, and the storage requirements are within reach of a moderately rich person, but you have to actually generate them first. You'd need a computer with ~50-100TB of RAM and ~10-20PB of storage, plus lots of time and a couple mil for th...

Re: Stockfish with new NNUE architecture and bigger net released

I think what he's saying is that on-line and in the cafés AS is regarded as computer chess's foremost thinker and perhaps the architect of its future.

Re: records for chess games

Chess Query Language can help you filter and sort collections of games by complicated criteria, provided you are willing to spend some time to learn the syntax. There are also various collections of example CQL queries that you can learn from and adapt. For example, you may be interested in differe...

Re: You can't get there from here...

Retrograde move generation is obviously trivial, though it's not necessary here. The difficulty lies in efficiently finding a path between any two nodes on a rather large game tree. You should probably develop a heuristic that scores a position based on how close/similar it is to another. Material c...

Re: A random walk down NNUE street ….

An NNUE engine with a random net is a random mover. Surprisingly, no. Searching is a very powerful idea, so powerful, in fact, that to some extent it doesn't even matter if you literally don't understand what it is that you're searching for. In the context of chess, this is called the Beal Effect, ...

Re: correspondence chess in the age of NNUE

You are right that there's little that can be done about the influence of computers in correspondence chess, but the topic here is draw reduction, which is a completely different issue. You can either change the start position (i.e. chess960 or mandated openings), or change the rules. For me the on...

Re: correspondence chess in the age of NNUE

There's probably nothing that can be done to remove the overwhelming influence of computers in correspondence chess at this point, even with modifications to the game big and small. Implementing most rules changes into Stockfish would take a decent programmer all of minutes to hours, and then they c...

Re: NNUE nets with depth of 20?

There's also a sense in which you usually don't want to store knowledge in the network if it's fairly likely to be quickly and correctly elucidated by search. Without a doubt picking an arbitrary constant depth isn't correct, and evaluation depth on training positions should be dynamically adjusted ...

Re: Any position on which (top) engines disagree?

Sure, just look at the latest TCEC superfinal. Any unavenged win must represent a relevant difference of opinion.
