Re: Rise of the mighty NN

Giraffe was released in July 2015.
First appearance of AlphaGo October 2015.
The fact that they hired him shows they thought his ideas were good.

Re: Leela Chess Zero Makes Mind-Blowing Piece Sacrifice!

If Judit Polgar had been born at a different time, it is conceivable that she could have been world champion.

Of course, if a frog had wings, he would not scrape his butt on the rocks.

Re: Rise of the mighty NN

You do realize that Matthew Lai was one of the key programmers on the Alpha Zero project. His CPU engine played fairly well, despite an incredible burden of floating point more taxing than a CPU wants to bear. I suggested switching to GPUs long before the Alpha Zero project (but Matthew was not too ...

Re: Allie's Missed wins TCEC S18

It is not solely a NN problem to miss wins. I have seen AB engines up a full piece and then not win the game. In fact, I guess that most losses or draws, somehow or somewhere, contain a missed win. If we could see out 1000 plies tactically, we could perhaps exploit an absurd number of missed win pos...

Re: Rise of the mighty NN

You are correct in your assertion that multiple NN engines gives them enhanced winning chances. If one million stockfish engines were entered in a contest and there was one NN engine of about equal ability, the NN engine would lose. Especially in a short contest, an engine may play 100 Elo above or ...

Re: The Speedy Rating List

Given that a lot of engines have exactly 41 errors it would be interesting to know which positions (or even 1 of them) these occur in. 4Rk2/2R5/2p3p1/3p4/3P3r/P7/1P3P1p/7K b - - bm Kxe8; ce -32000; acd 0; k5rb/3r4/1ppP4/p1p1p1p1/P1P1Pp1p/1P1R4/3R1PPN/3q1K2 w - - bm Rxd1; ce -32000; acd 0; 8/3P2k1/5...

Re: Call an engine from BASIC?!

The next task in my project is to convert pgn-games in short notation into e2e4 d7d5 etc. or into epd's. PGN-Extract by David Barnes can do that (and more): https://www.cs.kent.ac.uk/people/staff/djb/pgn-extract/ Here are the output formatting options: -W[cm|epd|halg|lalg|elalg|xlalg|xolalg|san|uci...

Re: Ryzen 2 and BMI2?

The 3970X is a nice processor, it has some strange quirks too, and what I don't like about it is that it draws a lot of idle current, this is something I don't want for a workstation that runs 14 hours per day. My usage pattern is different. I run mine pretty close to 24 hours a day and it is almos...

Re: Is EMAN the future number one?

Most of the above programs are open source and you can examine for yourself and decide if you think someone has taken code beyond fair use. Quite frankly, I do not understand why people think it is OK to break the law. It is just as puzzling to me as the original law breakers. Hmm... I'm not so sur...

Re: Zenmastur vs Ovyron No it's not another GROB II!

[FEN "4r3/5pk1/1q1r1p1p/1p1Pn2Q/1Pp4P/6P1/5PB1/R3R1K1 b - -"] Another perhaps more surprising thing is that the above FEN PGN expression above is not allowed. You have to have 0 1 appended like this: [FEN "4r3/5pk1/1q1r1p1p/1p1Pn2Q/1Pp4P/6P1/5PB1/R3R1K1 b - - 0 1"] You would *think* if there were n...
