building the noob livebook version of Stockfish for Windows

I was trying to help someone else, but I can't seem to get it right either. It seems that the curl library has a pile of dependencies and I cannot figure out the right way to add all the necessary libraries. https://github.com/noobpwnftw/Stockfish/tree/livebook My experimental LDFLAGS looks like thi...

Re: SPCC: Testrun of Fat Fritz 1.0 finished

I get a big difference between 12 minutes (720 seconds) per position and 3000 seconds per position, analyzing opening positions.
So I think that they are like other engines and do better with more time.

Re: Engine release: weiss

I think your approach is a good one.
By that, I mean focus on search.
Every trim of the branching factor is an enormous speedup.

Of course, your eval is helping you decide what to trim, so eventually it will need some attention.

Re: Engine release: weiss

Edit: Is there a reason you added -mtune? I was under the impression that as long as -march is available it implies -mtune? An oversight. march is stronger than mtune and covers both. I always do mtune so that my builds are optimized for the machine I built them on to some degree at least. But inst...

Re: Engine release: weiss

It has an impressive branching factor and very high NPS for a single thread. I can't compile for PEXT here, so I muddled with the makefile. I also added this for ucinewgame: else if (BeginsWith(line, "ucinewgame")) { ParseFen(START_FEN, pos); /* DRC: I put this here. */ ClearHashTable(pos->hashTable...

Re: NNs seem to solve the Gusev Qxe5!! easily.

On the other hand, I have positions where NN engines toil for an hour without finding a tactical solution that alpha-beta engines find in a few seconds.

When you only have a hammer in your tool kit, everything looks like a nail.

Re: Fat Fritz destroyed Stockfish!

Re: "The supervised learning brought little even style wise."
my impression is that fat fritz is clearly better than the average nn tactically and worse positionally.

I have no idea how this translates to games
