New engine releases 2020

[Guenther]

not yet mentioned:

Olithink 5.8.9 (permanently updated dev versions)
http://brausch.org/home/chess/

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.

I did the same for Cinnamon 2.31, its release compilations also don't run anymore here.

Both programs versions will be uploaded soon to my usual download site.

Why is it called final release? I hope you won't call it a day.

Thank you, Guenther. I do not have any patches under testing, and I do not plan on working on Combusken.

Test gauntlet already running.

However, I don't understand your decision to quit. The first public release was only a little more than half year ago.

Sad to hear that, Marcin.
Thank you for your efforts, and for sharing your fine engine with us.

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

I have compiled Cinnamon on Linux, too (Won't compile with MacOSX/clang), but I get some annoying messages with cutechess-cli:

Code: Select all

Warning: PV: Kd4 h3 Ke4 Re2+ Kd3 h2 Kxe2 h2h1
Warning: Illegal PV move h2h1 from Cinnamon 2.3.3 (59)
Warning: PV: Kd4 h3 Ke4 Re2+ Kxf4 h2 Kg3 h2h1
Warning: Illegal PV move h2h1 from Cinnamon 2.3.3 (59)
Warning: PV: Ke4 h3 Kxf4 Re2 Kg3 h2 f4 h2h1
Warning: Illegal PV move h2h1 from Cinnamon 2.3.3 (59)
....

I saw such message with other engines, too, but not in this quantity. Perhaps the author want to fix this

I get some annoying messages with cutechess-cli:

I will probably not teach you something, but here is what I put at the end of my command line for cutechess-cli. It solves the problem of the annoying messages:

Code: Select all

 2>> error.log

and even better:

Code: Select all

 2>> error.log | tee tournament.log

Sophos keeps deleting Counter 3.6.

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.
