Re: Rumored Threadripper pricing

WTF are they thinking. Right now they are thinking "we're fucked" 5 years ago when they got stuck on 14nm they were thinking "these magic 3D trigates put us way ahead of the competition, so even though we know of no way to make 3D trigates work on 10nm, we are so far ahead..." To frame this complet...

Re: IN 100 games if SF reaches 51 in TCEC it should be stopped

monte carlo tree search produces blunders by design while the root move may be "well sampled" and avoid hanging pieces, the 2nd ply is less well sampled, the 3rd ply even less well sampled, the 4th ply poorly sampled, the 5th ply even more poorly sampled, ... This is the core fact of monte carlo tre...

Re: PGN standard, its improvement and standardization

Sure, users wont program their own parser. Authors do that. There are fewer authors than there should be, because parsing pgn requires a full bug free move generator, and therefore there are fewer programs for those users to enjoy. PGN wasnt meant for automated computer consumption. Excuses, that in...

Re: Coverity Scan

coverity search for security vulnerability in your code That's not entirely correct. They also find dead code, null pointer dereferencing and tons of other things. One mans "dead code" is another mans "old version of the eval" or "known to be bug-free alphabeta" Yes these are things you wouldnt wan...

Re: A pre-calculated pawn hash table ?

The examples you give are STILL ones where the game is heading towards a non-draw result. It doesnt matter which side is winning. Well, so don't give him an extra Queen but an extra Rook. Point is that differences in piece material, like the exchange, Rook vs 2 minors, Bishop pair vs B+N can always...

Re: A pre-calculated pawn hash table ?

You cannot guess the game outcome from the Pawn structure. A Pawn structure can be awful, like two isolated Pawns aganst 6, where 4 of the latter are connected passers. But if the side with the 2 Pawns is a Queen ahead, it would still be a trivial win. However bad a Pawn structure, it can always be...

Re: A pre-calculated pawn hash table ?

Food for thought:

Pawn structures where a player has a "bad" formation maybe arent important to cache because the "elo cost" of the "extra work" might be made up for by the fact that one side already has a "bad position" and the game is likely already heading towards a non-draw result.

Re: Are there any benchmarks for LC0 on the new AMD 7nm GPUs?

AMD bet on OpenCL but it "lost" so its no wonder their investment in it became sketchy. Their OpenCL 1.0 SDK would seamlessly mix CPU and GPU which was what I was after early on, as I had one of the first 6 core consumer chips available (The Thuban line of Phenom II processors) - this was when the n...

Re: One idea to solve chess?

EGTB's are desirable because they are FAST. The classic Time vs Space tradeoff. NN's are not even close to optimal models of any domain. Not even close. Keep that in mind, that its not even close. Let me say it again, that it is not even close. Very far from optimal. So very far. Let me say it again...
