REBEL-EAS

Subject: REBEL-EAS Mon Aug 21, 2023 7:22 pm

REBEL-EAS is an in between version based on the same, but more, neural net data as REBEL-16.2 but heavily modified during the last 5 months in order to make REBEL to play more aggressive and runs as a module under Chess System Tal 2.0

. REBEL 16.2 gains an EAS score of : 80.258
. REBEL-EAS gets an EAS score of : 160.569

As a cherish on the cake the playing strength of the neural net has increased with 20-25 elo using balanced positions. Using the TCEC positions composed by Jeroen Noomen and GM Matthew Sadler adds another 26 elo points while the draw rate dropped with almost 20%.

Cool....

I don't hold my breath about the really, EAS scores fluctuate on 1) the engine mix, different opponents gives different EAS, 2) used opening sets, REBEL-EAS does best on balanced positions as I found out and 3) of course a valid elo pool.

For my testing I use 10 fixed opponents within a range of -30|+30 elo using balanced positions. During a training run of ~400 epochs I play about 15-20 matches of 2000 games and calculate the EAS which (for REBEL-EAS) fluctuate between 100.000 and 200.000. Lumping them together (at least 20.000 games) gives a reliable EAS score, but..... 1) for that particular elo pool and 2) that particular opening set.

And so I was able to make a comparison between REBEL-16 and REBEL-EAS but only for that particular elo pool and that particular (balanced) opening set.

I tried other sets, randomly picked one of your UHO opening sets, tried my gambit positions and the EAS score dropped significantly. And what to say about the TCEC positions, REBEL-EAS gained 26 elo [!] more than all other sets but the EAS was not so great, but in all cases always better than REBEL-16.2

Adding all things together I managed to create a more aggressive engine and that's hard enough with NNUE and your EAS tool was very helpful, actually the best what is available, but to say and I quote "Then we will see, what the EAS-scoring of Rebel-EAS really is" as a sort of absolute truth are a couple of bridges too far as I stipulated in the above, best summarized as, it depends.

Clover has tremendous potential. With a time control of 4 min + 2 sec, however, it is still weaker than CSTal 2.00. In the current TCEC tournament, Clover has qualified for the main tournament.

Ratinglist-testruns of Rebel EAS finished.

https://www.sp-cc.de

https://www.sp-cc.de/uho_ratinglist.htm

Also take a look at the EAS-Ratinglist, the world's first engine-ratinglist not measuring strength of engines but engines's style of play:
https://www.sp-cc.de/eas-ratinglist.htm

(Perhaps you have to clear your browsercache (press STRG+SHIFT+DEL) or reload the website))

We see a clear progress in the EAS-Ratinglist: Number of sacs is quite good (25.64%) und much better than Rebel 16.1 (17.22%). Number of bad draws is clearly smaller, too (progress,too) for Rebel EAS. But the overall length of all won games is worse (84) compared to Rebel 16.1 (80) and the number of short wins is a little bit worse (no big deal, but 11.98% short wins is overall not a good value).
So a lot of room for improvements for Rebel in the EAS-List: A new Rebel, which is winning games faster, will lower the overall length of all won games and will raise the number of short wins, too...both would mean a gain of EAS-points...

  36 82699 17.22% 12.96% 24.10% 80 Rebel 16.1

By the way: The EAS-Ratinglist built out of the UHO-Top10 Ratinglist games show exactly the same as the "normal" EAS-Ratinglist:

*** Average length of all won games: 77 moves

(Number of sacs and bad draws is good for Rebel EAS, overall length of won games and number of short wins are bad. What we learn is, that the EAS-Tool produces very similar results (in the single statistics, compared to other engines (do not just look at the EAS-score!!!)) in different databases, if the number of played games is big enough).

Subject: Re: REBEL-EAS Sat Aug 26, 2023 10:06 am

Surprised by the elo gain, must be the longer time control.

Thanks for playing 16,000 games, that helps too.

Subject: Re: REBEL-EAS Sat Aug 26, 2023 10:18 am

Regarding EAS, I keep on saying that, in my test elo pool against 10 other engines the pool varies -30/+30 elo and then REBEL-EAS is clearly on top of the rest.

But nevermind, the next version (if ever) the focus will be on playing strength, the EAS version was just a fun exercise.

. REBEL 16.2 gains an EAS score of : 80.258
. REBEL-EAS gets an EAS score of : 160.569

As a cherish on the cake the playing strength of the neural net has increased with 20-25 elo using balanced positions. Using the TCEC positions composed by Jeroen Noomen and GM Matthew Sadler adds another 26 elo points while the draw rate dropped with almost 20%.

Congrats, Ed!
Are broken book issue fixed? Thanks

If you activate "bookdepth" then yes.

This doesn't work for me.

I am using the Fritz17 GUI, does it work for others?

Install REBEL-EAS.EXE in the same folder as Chess System Tal 2.0

Book are stored in the polyglot-books folder.

As Rebel EAS is working engine-wise I assume I have set up the engine correctly in principle.

Also the book is working with Rebel 16.2, so I assume the book is set up correctly, too.

I am out of ideas.

Happy Christmas time!
