OK, we are still mucking around with this. Joshua is compiling using the latest MSVC stuff. Here's our problem (I don't have a windows box to try this on so am getting compile help.) We can access __popcnt() with no problems including intrin.h. but we can NOT access __popcnt64(). Apparently the com...

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...

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...

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 ...

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 ...

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...

Is it possible? How? I would like to try.

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...

Don't you think that the network can learn to predict tactics?

1. Feed-forward NN - maybe, very shallow tactics
2. Recurrent NN - one day perhaps, but not today, not tomorrow,...

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 :...
