Re: One idea to solve chess?

Let's say it was possible. I doubt that one could store the number of weights needed for that network because I dont think current networks arelarge enough to give a perfect answer to any chess position Has anyone tried to compress the data of a 3 men tablebase in a NN and get the same result? That...

Re: syzygy request for info

I have just read KNNvKB files and and in all the pairsData struct contained the order of pieces seems to be: white King, black King, black Bishop, white Knight, white knight. does it apply to all the files? or it can be that each pairdata inside a file can have different piece order? Why do you wan...

Re: Opposite Color Bishop Endgames

Not at all. Having a high Elo can be achieved by only doing good moves in a sub-set of all chess positions, namely the positions that can be reached by the moves you select. You can arbitrarily suck in positions that you will never reach because you avoid them. And I would not call an entity that h...

Re: DTM50

As you are aware (see the top two posts), a tablebase that only lists DTM50 when entered with the ply counter at zero cannot reliably be used to find moves when the ply counter is larger than zero. So you won't be able to play perfectly. Of course. This is why I say one should play by DTC50 when yo...

Re: asmFish

I'm auditing the games now and something interesting is apparent. It was my perception while watching the games that while asmFish was 1,000-2,000 kN/s faster, SF seemed to search deeper. I just shrugged this notion off, thinking "That's impossible!" After all, asmFish IS Stockfish, just an outdate...

Re: asmFish

... asmFish has been functionally identical to Stockfish ever since. So the difference between asmFish and the corresponding version of Stockfish is speed and only speed . If you are right what was the sense to make asmFish AND pedantFish simultaneously? asmFish included a few speed optimizations t...

Re: asmFish

It would not be a superfluous test because Asmfish is not an asm-copy of Stockfish and the difference between them more then the speed. There was a real copy named pedantFish, but this version ended in the past. The old asmFIsh was replaced with pedantFish when it was found that pedantFish was abou...

Re: DTM50

I'm curious, what engine was this with? Seems quick!! :) Will check Stockfish, Fritz 14 (uses Nalimov) and a few others to see how they compare. That was with Cfish, which supports my DTM files. Unfortunately, running it with 6-piece DTM files slows it down to a crawl (once the search gets into mat...
