...that make Leela on top 5 engine behind Stockfish , Komodo and Houdini.
In CCC’s own championship both Komodo and Houdini finished outside the top 4.

Re: a crying shame (re: self-learning engines)

Yeah, I don't think dkappe understands the kind of learning we're talking about. ...Then the user does some "reverse analysis", where previous nodes are visited. Leela would use what it has learned from the future position to have a more accurate score of the line, and would either remain showing t...

Re: How do you know if your cpu is equal to your gpu?

Well, I’m glad you have a favorite ratio. Cscuile has had so many ratios with so many formulas and acronyms that I couldn’t keep track of them all. But his heart was in the right place.

If one ratio "works" (i.e. allows comparison) across different time controls and hardware, as you suggested before, then another more meaningful ratio should also work.
More meaningful? Ratio = C * leela nps / sf nps. The only thing that changed was the C. Meh.

Re: How do you know if your cpu is equal to your gpu?

There was an attempt to create a better “leela ratio” maybe a month ago. It turned out not to be successful. In what way was it unsuccessful? Too complex and unworkable vs a simple benchmark. Why hasn't there been more interest in Cscuile's ratio? Obviously it takes some effort to find (if it chang...

Re: How do you know if your cpu is equal to your gpu?

That of course depends on the curves (performance vs. time or nodes per move) being the same shape, so again there's need for those curves. There was an attempt to create a better “leela ratio” maybe a month ago. It turned out not to be successful. Instead they decided to peg a ratio at that of the...

Re: How do you know if your cpu is equal to your gpu?

You asked a controversial question: when are cpu and gpu “equal?” At best it’s difficult if not impossible to answer. How do you define “equal?” A much more useful question would be “how do I know if matches run on two different machines between gpu and cpu engines are comparable?” A primitive appro...

As stated by the author, it’s based on stockfish and lc0 source.
He says it, you prove it, and you still complain. That's childish. cry baby, cry.
I’m not complaining. I’m making a request for the source code per the terms of the GPLv3. Simple.

Re: Alpha subZero - NN for CPU

The author responded to me on chess2u website. This is what he wrote: I would not like to publish the code because everything is a method of trials and plaids full of some function that was later thrown away and I would have to clean this code. It is too much time and I do not want to do it just to...

When asking about something in anger you accomplish nothing, even if the person violated GPL license, best is to do it in polite way, and than hope for the best. :) :)
I’m not angry. I’m just making a request. If anything, I’m disappointed that I keep having to explain the GPL.
