which is a bit awkward.

Would be nice if someone could try the bmi or bmi2 version, if those run at all and with what speed.
The other two are are tested here and behave very similar at least on my old machine.

I used go depth 10 for measurements.

sapeli_165.exe: 2614849

sapeli_165bmi.exe: 2675111

sapeli_165bmi2.exe: 2697810

This one was strange, it took much longer to reach depth 10 than any of the previous ones, still the nps is bigger)

sapeli_165default.exe: 2491669

This one took more than 2 minutes to complete.

My PC: i5-4690K at 3.5 GHz

Interesting. I used depth 9 and depth 10 a few times too for measuring and also noticed that depth 10 would need
sometimes more time than I had patience, but i don't remember if it was for both non bmi compiles or just one.

BTW shouldn't the bmi compiles be quite a tad faster normally?

But they are a bit faster, aren't they? Anyway, I don't know, must depend upon the engine architecture.

^ Thanks for the builds again! Added them to the list: https://github.com/SamuraiDangyo/Sapeli ... naries/bin

About the different NPS. Sapeli has a little bit noise on evaluation. So it doesn't produce the same NPS every run.

Here is wac.epd on Sapeli. Not sure how useful this test suite is. Sapeli 1.65 gets 260/300.

I released Sapeli 1.66

Release: https://github.com/SamuraiDangyo/Sapeli ... /tag/v1.66
Source code: https://github.com/SamuraiDangyo/Sapeli

There was some bugs in 1.65 so...

Bugfix in fen rule 50. Now Sapeli actually analyses this:

Code: Select all

sapeli -fen "8/8/6p1/6Pp/4R2P/2K4k/8/3r4 w - - 91 111" -search 1000
info depth 0 nodes 51 time 0 nps 0 score cp 12 pv e4f4
info depth 1 nodes 340 time 1 nps 340000 score cp 11 pv e4f4
...

Some ELO improvements: (17.86 +/- 9.82 ELO) vs Sapeli 1.65
I sort castling moves higher than before. I want Sapeli to castle ASAP.

Test suite support: wac.epd is shipped in the package.
Easy to run:

Code: Select all

make wac

Some test suite results for Sapeli 1.66 (profile build):

Code: Select all

WAC.epd
score=261/300 [averages on correct positions: depth=3.7 time=0.37 nodes=1036024]

WAC Albert Silver 200 positions
score=175/200 [averages on correct positions: depth=3.3 time=0.20 nodes=550509]

Bratko-Kopec Test suite
score=16/24 [averages on correct positions: depth=4.2 time=0.58 nodes=1885025]

Noticed a wrong link for my new compilations for Sapeli 1.66 - this is corrected now.

http://rwbc-chess.de/download.htm

JohnWoe · Post by **JohnWoe** » Wed Dec 25, 2019 2:34 pm

Thanks for the builds!
Added them to the list: https://github.com/SamuraiDangyo/Sapeli ... naries/bin

Those WAC results were surprisingly good as Sapeli is a shallow searcher.

Looking at the rating list: http://ccrl.chessdom.com/ccrl/404/rating_list_all.html
It seems like I have made some progress. It makes sense as 1.64 is much less buggy than 1.0

Sapeli 1.64 64-bit 1939
Sapeli 1.0 64-bit 1780

JohnWoe · Post by **JohnWoe** » Thu Dec 26, 2019 1:59 pm

I released Sapeli 1.67

Release : https://github.com/SamuraiDangyo/Sapeli ... /tag/v1.67
Source code : https://github.com/SamuraiDangyo/Sapeli

Went through the code 100s of times and cleaned it up.
Improved code a lot.
Tons of simplifications.
Better documentation(Better variable names etc).

Slightly better than 1.66.

Code: Select all

Finished game 2447 (Sapeli 1.67 vs Sapeli 1.66): * {No result}
Score of Sapeli 1.67 vs Sapeli 1.66: 1053 - 957 - 436  [0.520] 2446
Elo difference: 13.64 +/- 12.48

JohnWoe · Post by **JohnWoe** » Tue Dec 31, 2019 8:22 am

I released Sapeli 1.68

During simplifications I noticed an EP bug in capture function. Been there forever. Now it is fixed.

Source code: https://github.com/SamuraiDangyo/Sapeli
Release: https://github.com/SamuraiDangyo/Sapeli ... /tag/v1.68

Lots of speedups + simplifications.
Also changed Perft suite a bit. Now there's 10 old positions (+ 20 new Chess960 positions) so speed can be compared between old versions.

In my tests it is scoring well against older versions (due to fixed bug?).
