Re: Can an engine calculate how fast Human GM lose ratings after 55 ?

I have a belief that chess strength has something to do with Testosterone levels. It declines as we age and Testosterone is much lesser in females. Do go on! It's always interesting to hear about the absurd and logically indefensible ideas that people form in their little heads without the slightes...

Re: Stockfish: Our lawsuit against ChessBase

What's mysterious about wanting ChessBase to fail? They have repeatedly acted in bad faith, contravening both the spirit and the letter of the GPL. At some point, bad behavior becomes so severe that it's rational to believe that social welfare is maximized by removing entirely the ability of the bad...

Re: Stockfish: Our lawsuit against ChessBase

leading developers of Stockfish have terminated their GPL license with ChessBase permanently Is this possible? You can sue someone to comply with the terms of the license. But since a FOSS license offers the software to anyone who complies, curing any violations should enable continued distribution...

Re: Can an engine calculate how fast Human GM lose ratings after 55 ?

It's certainly no mystery that not-quite-world-class athletes (and chess players, etc.) have the potential to maintain a relatively consistent level of performance as they age, whereas the best of the best do not. Obviously absolutely no disrespect meant to Larry Kaufman (or anyone else), but as he ...

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: 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...
