Is EMAN the future number one?

[corres]

I think it is more better to use a good book or Brainfish and analyze the lacking positions with a good engine, like Stockfish/Brainfish.
A good engine can weight the positions in the book. This behavior is in Chessbase Fritz engines from the 1990' years!

CB books are not so helpful when it comes to deep analyses and position evaluations. For interactive analysis, statistics are less important. I prefer Shredder or Eman. In the past I often worked with IDeA (aquarium).

CB books are good for OT players, aquarium is a good tool for analyze, but I prefer simple CB GUI with Stockfish and Leela.

PS: The author of Eman will certainly be happy that there are now already two people in this forum who are dealing with his engine...

He won't be happy when one of them rightfully requests the source code.

I don't think he cares. Probably it's enough for him that he can beat Ethereal & Co. with a score of 85:15 (or so)...
But don't get it wrong: Ethereal also has a good minute here and there:

First I will run some tests with no learning enabled or being used. Then repeat with learning on and then repeat with learning on and being used. I suspect this might do very well indeed if the learning was implemented correctly.

It'd be interesting to compare Eman's learning with SugarNN's NN learning. Specially because perhaps all Eman's author did was copy-pasting Sugar's learning and changing the names.

Anyway, congrats for showing Honey>Eman I was afraid Eman's time management improvements would compensate, but it's clear they're only relevant when the book keeps making the engine play too early.

... all Eman's author... how many??

SF devs beat Ethereal (I guess I win either way?). Not so sure this mystery man has done anything of substance.

You could end this whole thread by emailing Eman a request for the source code under the GPL.

If Eman really is a wonder of the world, it would be a shame to keep it hidden, right?
Let the chess world share in its glory. Let the brilliant people from Stockfish improve upon the ideas in Eman.

[Ovyron]

Not so sure this mystery man has done anything of substance.

He has shown that we can get many features that are currently in different Stockfish clones in a single one. We could have Eman's source today (because the code is already out there, but it's scattered among many Stockfish clones), or something better (since Honey already performs better than Eman) but only this mystery man has gone and made the collection.

Only 50 threads are used for the games. This keeps 14 threads in reserve for me to do other things and it also boosts the nps a little bit. If anyone is curious about the scripts , let me know. Cutechess is managing the match.

Have you any experience about Elo difference between Threadripper 16 physical cores and Threadripper 32 physical cores if clock speed is about the same? Maybe from a table of tests result.

30 Elo or less...

Code: Select all

Cores   Elo

please learn how to quote properly, it's not good form to mangle or make up quotes - thank you.

What is your problem?
From your text it seems to me Eman has more than one author. If we count the authors of Stockfish also, it would be true.
