Re: Komodo 13.3 released

Yeah, so I guess the Komodo team could provide a "buy once, get all future versions of the program for free" package, for a price they deem acceptable. I was getting all the Chiron engines for free just because I gave some feedback, so it's not inconceivable to be able to get them for free for life...

Re: Komodo 13.3 released

I have no issue with Komodo authors making money from their work by providing an useful product, even if it doesn't have as much raw elo as Stockfish. The one thing I don't like is that the engine being commercial incentivizes not sharing their good ideas while nonetheless taking some good ideas fr...

And when the free latest version will be downloadable.
We normally upgrade the free version when we go to a new main version. So perhaps we'll upgrade what we distribute for free when we go to Komodo 14, but that hasn't been discussed yet.

Re: Komodo 13.3 released

Congratulations. Hopefully, the expected gains will hold in rating lists. Since the estimated 15 elo gain is based on Ordo, it should be a good estimate for CEGT and for FastGM lists which also use Ordo. CCRL uses BayesElo, which tends to compact the Elo numbers, so the best guess on the CCRL lists...

Komodo 13.3 released

We have released Komodo 13.3 at komodochess.com. It is a significant strength improvement over 13.2.5, the last release. In standard mode, the gain is about 15 elo points. Since most of the gains are due to better scaling with more depth, the short searches used by MCTS don't benefit much, so the ga...

Re: An idea for a different type of tournament

I don't know which engine would be best, but it is safe to predict that Lc0 and most if not all of the NN engines would be the worst. I think it would be more interesting to do this with just knight odds instead of queen odds, because once the eval gets up to about two pieces plus or the equivalent ...

Re: Could we use partial scoring for draws to improve evaluation of engine vs engine matches and tournaments?

Every decent engine knows what is mating material and what is not. The typical situation that ends up with (for example) king and knight vs king is that one side gets a favorable ending, neither engine can read out to the end whether Black can reach the drawn king vs king and knight or not, but the...

Re: Could we use partial scoring for draws to improve evaluation of engine vs engine matches and tournaments?

At the very least, if one side has material and is on-move vs a lone king, giving him 3/4 of the point (as proposed in the correspondence chess thread) (perhaps conditioned on the pawn or piece being not lost by force) in testing seems reasonable. So an engine that doesn't know two knights can't ma...

Re: Could we use partial scoring for draws to improve evaluation of engine vs engine matches and tournaments?

There have been various proposals over the years to change the rules of chess to reduce the number of draws. Correspondence players want something done https://en.chessbase.com/post/how-many-points-should-you-get-for-a-draw and there is a precedent in other games like Janggi (Korean chess) https://...

Re: Stockfish 11 at 120k nodes per move

Thank you Larry for your interesting input. To complete, my initial post, I ran SF11 @ 120knpm vs SF11 @ 360knpm. It appears that by eyeballing the doubling at 200 elo in that npm range I overestimated it somewhat. My data for SF from may is 180 elo from 130k to 260k and 130 elo from 260k to 520k. ...
