Re: Crafty 25.3 Release

Where do I find a list of available Crafty executables anyway?

Bob's university account is no longer.

Re: SIMEX 2.1

I think Hiarcs, Gandalf, ProDeo regarding the evaluation belong to the old-class generation before the open source revolution of Fruit, Strelka, Robbolito and currently Stockfish began and were not influenced, hence low similarity. I added a few oldies, Ruffian, Hiarcs 13 and Shredder 8. Seems to co...

Booot and RofChade. Both produce indentical weird EPD output.

Re: SIMEX 2.1

After inspection I made some changes to the "ccrl.htm", removed the following engines: Laser - doesn't support the UCI depth command. Fizbo - doesn't support the UCI depth command. Protector - doesn't support the UCI depth command. Unrealistic low numbers Smarthink - can not check it since the data ...

Re: SIMEX 2.1

Of course, all Stockfishes are derivatives of earlier Stockfishes. As programs such as Booot6 and Hiarcs14 show us, the similarity score for independent programs (well, I assume, and the data confirms) is down in the 30 to 40% range. Many, many programs that Ed has tested score 30-40% across the bo...

Re: SIMEX 2.1

Here is a question: Is it wrong to use another engines evaluation terms, if you wrote your own code to do it? If it is, where is the cutoff? For instance, lots of engines will have wood value of about 3 for knights and bishops. Pulled it right out of the chess book. Lots of engines will have a bish...

Re: SIMEX 2.1

Looking at your ccrl.html, massive cross table of engine results on the SimTester, I’m wondering what the similarity numbers mean. This is a list of low similarity programs in general, but one or two things jump out. Booot6, very consistent results right across the board, it gets 25% to 30% similar...

Re: SIMEX 2.1

what is the origin of the testing suite? who composed it, or did it just grow, and when was it composed? Do we know how it was composed? Don isn't longer among us, but maybe Larry can tell. My best guess is that the 8238 positions were derived from comp-comp games. If you scroll through the simex e...

Re: SIMEX 2.1

Does Winter already support such a tool? What do I need to add to an engine in order to support a tool like SIMEX? I'm kind of curious what engines Winter (especially Winter dev) is related to :D EDIT: I'm trying things out in WINE now. I get the following error at the moment: Can't recognize 'sort...

41 high rated CCRL engines and no single 60% found!
I see similarities that go beyond that on the Stockfish versions, yet they're not colored yellow as the bottom of the page seem to claim they should be?
There are some irregularities, I will post them later.
