New engine releases 2020

[connor_mcmonigle]

I've released Seer 1.1 here: https://github.com/connormcmonigle/seer ... s/tag/v1.1 (this time with binaries!). It should prove substantially stronger than Seer 1.0 and also corrects an issue where an extra thread would be used. Estimated strength is around 3000 elo, though this a quite poor estimate due to limited testing. In any case, I'd greatly appreciate if it could be tested. More info can be found by following the link. Let me know if you have difficulty running it.

Sophos keeps deleting Counter 3.6.

http://talkchess.com/forum3/viewtopic.p ... &start=400

It's been showing up as a positive in most scans. You could try Tony Mokonen' compilation:

I've tried all of the ones posted so far.

I noticed that OliThink release compilations since version 5.69 won't run anymore on my old hardware.
Therefore I compiled current 5.89 now for no popcount with SSSE3 instructions.

Thank you very much! I am interesting in the changes to made in order to let it run without hardware popcount?

No changes needed, except changes for the flags in the makefile according to the hardware, the compiler does the workaround.
Sureley this no popcount version will run slower then on modern hardware, but I cannot test the difference.

In case of Olithink I just replaced -mavx2 by -mssse3.

[fabianVDW]

I have released a new version of FabChess at https://github.com/fabianvdW/FabChess/releases

Version 1.16 comes with a significant strength increase over the last releasted version 1.15 and a lot less code.
Changes include:
-Better handling of endgames
-Retune parameters with Andrews data
-Late move reductions changes
-Add new evaluation features: King piece (shogi-like) incrementally updated tables.
Currently only for pawns.

Selfplay tests show:

Special thanks to
-Andrew Grant for his public dataset
-Terje (author of Weiss) for submitting several cleanup patches
-Connor (author of Seer) for the idea of using king piece tables
-Noob for really existing
This release wouldn't have been possible without them

If someone could test out the Linux compiles and check if they are working and that BMI2 faster POPCNT faster old on a modern cpu that would be nice
