Very important SMP changes, for people running on moderate to very high core counts.

Congrats on the release.

In my ultra-bullet-tests 8.1 looks 141 ELO stronger than 8:

Code: Select all

   # PLAYER            :  RATING  ERROR  POINTS  PLAYED   (%)     W    D     L  D(%)  CFS(%)
   1 Halogen 8.1       :       0   ----  1331.0    2000  66.5  1128  406   466  20.3     100
   2 OliThink 5.9.0    :    -121     14   669.0    2000  33.5   466  406  1128  20.3     ---

White advantage = 12.99 +/- 7.45
Draw rate (equal opponents) = 21.89 % +/- 0.97

Code: Select all

   # PLAYER            :  RATING  ERROR  POINTS  PLAYED   (%)    W    D    L  D(%)  CFS(%)
   1 OliThink 5.9.0    :      20     14  1058.0    2000  52.9  851  414  735  20.7     100
   2 Halogen 8         :       0   ----   942.0    2000  47.1  735  414  851  20.7     ---

White advantage = 12.67 +/- 6.93
Draw rate (equal opponents) = 20.76 % +/- 0.92

Faszinating how almost everybody seems to surprise the 3000 quite easily. Others need over 20 years and still not there.

Cheng4 0.40dev compilations (sse4.1/avx2) by me
after I realized through the post from 'Archimedes' today that Martin had
started working on Cheng4 again since quite some time.

I've released Seer 1.2 here: https://github.com/connormcmonigle/seer ... s/tag/v1.2
This release should be ~200 elo stronger than the previous release.

Hippocampe 0.4.2.0.2.

Fixed illegal pawn move. (Thank to Taimo Peelo for reporting the bug.)
Added setboard command.

I released Sapeli 2.0 final.
This is UCI only version. The original Sapeli has no UCI and plays some chess like variant atm.

It's a weak engine. My guess is 1900 Elo. But it can be used as sparring partner for up-and-coming engines to higher levels.
I only focused on making code lean and mean. Special focus on KOTH960. Which is kinda fun variant.

Release: https://github.com/SamuraiDangyo/sapeli ... s/tag/v2.0

Thanks a lot. Assuming I can get it to compile without problems, I'm certainly going to use it in my testing. I always liked this engine, for the relatively high strength compared to its size and complexity.

...compiled a bunch of various flavours for windows...if there is enough interest I will upload them.
BTW I see you had 'hash' once already as an uci option. What was the reason for you to remove it and changing to fixed hash size at compile time?
