Re: Posted something in EO

My comment. The reason it was made private to start with was to allow a place to actively discuss the cloning / derivative status of programs without it becoming public. Programming-types will understand most of what is written and interpret it reasonably. A non-technical person not involved with co...

Re: PGN standard, its improvement and standardization

Steven and I had many discussions about PGN over the years. His required 7 tags was OK back "when". Neither he nor anybody else ever envisioned what has happened today with capturing and encoding far more information than ever imagined back then. My main complaint back then was with the EP field in ...

Re: macOS users, proceed with caution with Xcode v11

Apple has a very large developer group. They test continuously it seems. IE just the IOS developers have had more beta versions to test than I can count. That ignores iPadOS, macOS (MacBooks and such), Xcode and on and on... BTW. Mike. You might try doing a full macport update including gcc. There a...

Re: Endgame Novelty

I ran this with Crafty on my MacBook. It evaluates 27. a4 as an instant draw. If I let it think on its own, it chooses 27. f3 with a comfortable advantage for white... 22 1.99 0.17 27.

Re: Similarity Report 2019

The data speaks for itself, both positively and negatively. Exactly and since the data tell about the origins of the engines, this thread belongs to the Engines Origins subforum especially since this is not a certified tool of any kind I'ld be intriged to know what is a "certified tool" and where t...

Re: Using profiler on linux

Lots wrong there. Nodes should NOT change with optimization levels/types. They should remain constant. Suggests the usual undefined/unitialized variable sort of bug that you should try to find.

Re: Similarity Report 2019

I treat complaints as confidential, and was not planning on changing this policy. People must not feel impaired by fear for petty harrassment in retaliation for flagging wrong-doing. By the nature of things it are the most aggressve and viscious members that violate rules, and have a tendency to bu...

Re: Basic endgames

As a note, I just checked the position above. I ran with sd=4 (4 ply max depth) and no endgame tables at all. Crafty forced mate easily. If you don't limit the search to 4 plies it will find a mate in 7 instantly so it needs some help to make it rely just on the PSQ stuff I mentioned. Works well...
