Re: A Crossroad in Computer Chess; Or Desperate Flailing for Relevance

Just mentioning that there is also considerable art in the NN side of things. Perhaps as my own chess was always so weak, it was relatively easy for me to focus on the programming side of it. I imagine that might be more difficult for a strong chess player. With engines playing at super-human levels...

Re: "It must be a clone of some sort..."

What is exactly the reason to keep an engine private/closed? In my case with Tinker, I would be simply mortified if anyone saw the poor quality of the code. As far as sharing an .exe copy, back when Tinker was actively being worked on, there were simply too many changes to pick a stable version. Of...

Re: MSVS-2019 Oddity

Tinker is private. A handful of engine testers over the years have graciously included it in a few matches. Sergio Martinez ran it a few years ago in the "Swiss tourneys". It was about 2,500. In addition, it was playing quite a lot on ICC from January, 2000 until a few years ago. However, since the ...

Re: MSVS-2019 Oddity

And, that works nicely.
Now, down to only 18 W1 warnings.
I may have to expand to W2...
Thanks again.

Re: MSVS-2019 Oddity

Right. All I wanted was the constant definitions. I could do them explicitly, but it would be annoying for these: typedef enum {A1,B1,C1,D1,E1,F1,G1,H1, // in bitmaps most significant bit is A1 A2,B2,C2,D2,E2,F2,G2,H2, // but counted as bit 0 so A1-H1 is rank 0 A3,B3,C3,D3,E3,F3,G3,H3, // and white ...

Re: MSVS-2019 Oddity

Thanks for all of the suggestions. So, I compiled with /Wall to see all of the warnings using the current (default) MSVC compiler. There were more than 16,000. After fiddling a bit, there were then more than 19,000. Most of them seemed to be in Windows library headers of some sort. This was unmanage...

MSVS-2019 Oddity

I have not actively worked on Tinker for quite a few years, but from time to time I do compile and run it. My current PC has Microsoft Visual Studio Community 2019 Version 16.6.5 running under Win10 Pro. Amazingly, MSVC-2019 compiles Tinker. This is no small feat; Tinker is pure Frankenstein code, s...

Re: 3 fold repetition scoring issue

3 rep scoring can be quite tricky. Many A/B engines look for 3 reps at the root and score only 2 reps in the search tree as a draw. FWIW: I tend to think of 3 reps (and rule 50 moves) as more of a search issue, and not something in the eval (which typically has no knowledge of the prior positions). ...

Re: Off-the-shelf PC spec, engine development

I am far from a hardware guru, but have built and upgraded quite a few PCs over the years. My two cents: There is something just a little odd about the product listing. I'm having difficulty finding the exact CPU on Intel's spec site (ark.intel.com). That CPU is listed as an OEM in a few non-Intel r...

Re: Lc0 26.2 10x128 nets vs Stockfish 12

I could train another without the rule50 move counter which would be roughly about 20 Elo stronger, but it would take quite a lot of time (between one and three weeks). Before starting that effort, I'm trying to understand things a bit more. If I cook another net that is significantly better I'll pr...
