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: Particle Swarm Optimization Code

For anyone interested, I posted on my website the C# code I wrote that implements a multi-threaded particle swarm optimizer. See MadChess 3.0 Beta Build 75 (Eval Param Tuning) . I find the idea rather straight-forward and easy to understand. Each iteration a particle's velocity is influenced by ine...

Re: Singular extension ... again

But I thought that singular extension aimed at looking if in the current situation there is only one good move (and then extend). If depth of the tt move is enough, and we trust it, I was thinking that at least ttscore-pawnValue was the bound to use (in a fail soft framework). Maybe all those very ...

Re: Chess engine on ASIC bitcoin miner?

Is practical? Is it even possible? Surely a simple MTCS evaluation should be possible on it. No & no. ASIC - Application-Specific Integrated Circuit Bitcoin miner just performs SHA2 hash calculation. Nothing more, nothing less. It is not an FPGA (at least new miners are not an FPGA), and cannot be ...

Re: LCZero: Progress and Scaling. Relation to CCRL Elo

Hi Kai, what's about your last experiments with this opening suite ? Are last nets of LC0 (those >300) positionally better than Stockfish & Komodo ? Offhand, I'd say maybe, but that is a very speculative maybe. One cannot remove tactics from the equation, so oversights in its calculations will affe...

Re: Too much LCZero

I wonder if LCZero based posts could have their own place because it is hard to find other post among those related to it. And I hereby assure other authors not to be intimidated by the LCZero flood. I still love their engines and wait eagerly for new releases. Few years ago almost every post was a...

Re: Yet another Mate scores in TT thread

Okay, so storing mate scores into the table. I use these two wrappers when I read or write a value to the TT. I've seen this in most form posts, and it is also in Stockfish. I assume this looks good. int valueFromTT(int value, int height){ return value >= MATE_IN_MAX ? value - height :...

Re: AlphaZer0 versus Grand-Father 1/2-1/2, April 10th 2018

I do not like games Pablo is posting, but he shows that some engines are really really stupid. Just grab the space until everything is closed. Stupid.
