Re: TCEC season 13, 2 NN engines will be participating, Leela and Deus X

Numbers are not copyrightable, end of story, no ifs or buts. As for the other stuff, copyright is only valid if it is enforceable. And it is enforceable only if you can prove that perpetrator made financial gain by violating it. Other than that copyright is nothing but a toilet paper and talking ab...

Re: TCEC season 13, 2 NN engines will be participating, Leela and Deus X

The people involved in the Leela Zero Chess project obviously like to keep the "Zero" aspect and not introduce bias by pre-selecting evaluation terms. That doesn't mean it's not a very obvious enhancement for anyone else to use that doesn't feel bound by such a restriction and wants to train some n...

Re: TCEC season 13, 2 NN engines will be participating, Leela and Deus X

Because things like "compute some chess evaluation terms in the conventional way, and provide them as additional inputs to the net" make no sense at all. Conventional chess evaluation terms are nothing but numbers in centi-pawns. NN takes board representation in some format and extracts features. T...

Re: TCEC season 13, 2 NN engines will be participating, Leela and Deus X

It is such a simple idea that since LC0 appeared no one actually even tried to change the format of NN let alone "compute some chess evaluation terms in the conventional way, and provide them as additional inputs to the net". I am sorry, but I don't think you know what you are talking about. What m...

Re: TCEC season 13, 2 NN engines will be participating, Leela and Deus X

If I had to create a NN engine which improves upon Leela, I'd take the hybrid approach: compute some chess evaluation terms in the conventional way, and provide them as additional inputs to the net. This could result in better eval, enable one to reduce the net size (and thus improve performance), ...

Re: TCEC season 13, 2 NN engines will be participating, Leela and Deus X

I think that there is a difference because I guess that Brainfish derivatives are similiar in the choice of moves when LeelaChess derivatives with a new net are not similiar in the choice of moves but I am not sure about it and it may be interesting to see the difference in move choice between LC0 ...

Re: Wayback Archives search problem

Just today I visited the Wayback Archives and experienced the same behavior (a blank page) looking for an unrelated site. Normally, one either gets a snapshot history of the URL, or a message saying it isn't archived. This is probably a glitch of some kind, hopefully it's just temporary.

Re: TCEC season 13, 2 NN engines will be participating, Leela and Deus X

How come Hannibal is playing in Div 2? I thought it crashed out of it last season. You might be thinking of Chiron. It crashed 3/5 games in Div 1, demoting to Div 2. Div 2 had 5 of the 8 entrants losing from crashes, but none out by the three-strike rule, so I think they demoted the two worst perfo...

Re: Komodo 12.1

My understanding is that komodo MCT is a derivative of classic Komodo. I do not understand how people can think different when probably more than 90% of the chess code is the same. Note that I have no problem if tournaments allow derivatives to compete. It may be a "derivative" in a very broad sens...
