Re: Mate in 82?

Amazingly Komodo 12.3 announces mate in 82 after 44 seconds on my relatively fast laptop (i9)! Note there wasn't any forward and backward analysis. I did a clean restart of the Shredder GUI. Here's the output: 8/1p1p2p1/5p1p/5P1P/1p1p1P2/pP1P1P2/P1k1B3/4K3 w - - Engine: Komodo 12.3 64-bit [6-Threads...

Re: Further progress on new move generator

I am not sure I understand this. What information is in the lookup tables that would not be provided by the bitboard generation already? Is it that you store a lot of info on every move, that it pays to have an intermediate level of indirection through the pointers (so that later you would only hav...

Re: Further progress on new move generator

I think that move generators of this type will always be slow. Because the overwhelming majority of nodes in a search tree will be QS nodes, where you are only need captures. And the lookup tables do not provide a way to directly skip to the end of a slider ray; you would still need to test the boa...

Re: MadChess 3.0 Beta

Brilliant work Erik! Playing with Particle Swarm algorithms, both for chess and professional use, is on my to-do list.

Is LCZero Configured Correctly?

So I just set up LCZero for the first time (I know I'm late to the game). I have a laptop with a half-decent NVIDEA graphics card (GeForce GTX 1050 Ti), so I opted for the CUDU version (I've never used my graphics card in this way before). Once downloaded, setup was like any other UCI engine. It see...
