OK, thanks Ras. Here is code (that is only called when there are no pawns) from Vice that checks if a draw is likely with the remaining pieces. I was hoping for something a bit simpler! // sjeng 11.2 //8/6R1/2k5/6P1/8/8/4nP2/6K1 w - - 1 41 int MaterialDraw(const S_BOARD *pos) { ASSERT(CheckBoard(po...

It's a good idea to never do two null moves in a row. If I remember well, Vincent Diepeven was a proponent of two consecutive null moves to avoid zugwang; but, of course, triple null moves should then be avoided. A double null move has a flow, you can see in the discussion between Vincent and Chris...

I changed my null move pruning code to allow it to prune in the endgame and I've seen some great results with it. The compensation is that I decrease the null move search reduction from 3 to 2 in the endgame. I used to not allow any null move pruning if there are 3 or fewer non-pawn pieces for the ...

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 ...
