Seer

[Gerd Isenberg]

...
Again the appeal to engine authors - please create a separate thread if introducing a new engine or important updates. The new engines 2020 thread is intended for testers. It would be interesting to see whether AMD's PEXT beats the native C PEXT implementation, most use magic bitboards as fallback, specially if people demand 32-bit binaries
...

Sorry to clutter the new engines 2020 thread. I was uncertain as to whether creating a new thread or posting in the existing new engines thread was preferred. In any case, thanks for your interest in my engine.

No need to say sorry! You did not clutter this thread, which I introduced the same way, as the one for 2019.

Gerd is wrong in the way it would be intended for testers only, it was also created, because of easier doing research
in the future, instead of crawling through 1000s of single posts in the future.
(I am also announcing my compilations of programs sometimes, which are not updated with binaries or just source only)

Ok, but it's no fun to scan through 50++ pages with lot of engine sub-trees.

The CCW engine list is practically dead already, if I once should close my chronology too, other people could create
something reliable new, much easier.

May be I will revive the CPW engine releases page.

OTH Gerd is right, when he asks for additional threads from authors of new programs by themselves.

Thanks

I traced the issue with loading the Weights on Windows to Windows interpreting bytes equaling 26 as indicating the end of the file. I've now added binaries to the release page for version 1.0 and appended the version number to the engine's name. Binaries can now be found here: https://github.com/connormcmonigle/seer ... s/tag/v1.0

Additionally, I thought I'd share two nice games my engine played during some recent test matches (annotated by Lichess).

BTW, thanks for adding my engine to CPW Gerd! I've been casually following computer chess for many years now and have read many CPW entries. Consequently, it's pretty surreal to see a write up about my own engine on CPW. One minor note, Seer uses the killer move heuristic in move ordering as well.

I traced the issue with loading the Weights on Windows to Windows interpreting bytes equaling 26 as indicating the end of the file. I've now added binaries to the release page for version 1.0 and appended the version number to the engine's name. Binaries can now be found here: https://github.com/connormcmonigle/seer ... s/tag/v1.0

...

Thanks for the binaries. I still would like to create a core2 compile (if you have time for a makefile instead of cmake), may be I can squeeze a bit
more out of Seer for my old quadcore. What flags are used for the generic one currently?

Here is the generic compilation output with current 'weights' file from cmd:

THANK YOU also for this thread, for the great CPW .........and many more to Mr.Gerd Isenberg !

...

Sure. I can add a core2 compile in a little bit. For the makefile, I'm prioritizing exploring a new NNUE idea involving taking the game phase into consideration right now. I'm getting similar accuracy during training with a model which should be twice as fast.

In any case, the performance you're seeing is .... disappointing Slower than Leela on a medium to high end GPU.
If you want to compile using MINGW64 on Windows and can't get CMake configured, Seer should compile with:

(from the build directory)

Code: Select all

g++ ../src/seer.cc -o seer -march=native --std=c++17 -O3 -fopenmp -fconstexpr-ops-limit=1000000000 -I ../include/ -static

Superb and interesting engine ! THANK YOU ! In tests !

Thanks for testing! Could you share the processor you're using to test and the clock speed? I'm just trying to get a rough idea of whether my compiles are performing consistently with my expectations. (with an AMD r5 3600 @ 4.00 Ghz, I get ~400knps)

Intel i5-7400 (Kaby Lake)



In the first game of my test Seer 1.0 broke Deep Sjeng c't 2010 (a good blitz chess engine having 2925 Elo CCRL Blitz). My impression is that Seer has over 3000 elo points (at TC = 4 '+ 2 "). An impressive game. Unlike anything else seen so far in the NNUE area.

Awesome. The speed you're observing is about in line with what I would expect then. That's a very nice game. Thanks for sharing. In a 300 game 2+1 match against Glaurung 2.2, Seer tested at about +10 elo a couple of weeks ago. It's gained an estimated 40-50 self play elo since that point in time. I don't do very much testing against other engines, but I would guess it's still well below 3000 elo. It can be remarkably insconsistent at times, especially in endgames as a consequence of being so slow.
