Sugar: new UCI engine based on Stockfish

Weak engine.
Latest SDVs beat it easily in LTC games.

Perhaps it is strong only at STC games. I have it playing against Komodo 8

Try Test LTC games before expressing yourself .. you might change judgment

AmOs 4EvEr,
Thank you very much for your hard work. But i found 4 engines in x64 folder  AVX, GEN, POPCNT and 64 .exe.
What do they stand for? And which best for Windows 7 x64 I7 960 Modern Engines?

AVX= Advanced Vector Extension (Sandy Bridge - AMD Bulldozer)
POPCNT = modern CPU
64 = compatible with systems sse3
Gen= General CPU architecture

i7 960 Instruction Set Extensions SSE4.2 (best use POPCNT)

I'm a fan of your engine, where can i download the 5.1 beta?

Marco -

You apparently are not one to rest on his laurels. Already you are working on a new version of Sugar before 5.0 has even made all the rounds.

Well, I'm excited and will be (impatiently) waiting for you to release it!

Again, thank you VERY much for all you do for chess. The fact that you do it for free is very generous in my opinion.

Best,
David

P.S. - I've been running little tournaments with Sugar 5.0 and the results are excellent. One thing I've noticed is how Sugar outperforms Stockfish 6 at beating common opponents. For example; Sugar 5.0 beat Stockfish 5 12.5. to 5.5 while Stockfish 6 beat Stockfish 5 12.5 to 8.5.

Both beat Strelka 6 but Sugar basically inihilated Strelka 12 to 3! Here's something funny. One engine that is a challenge for Sugar 5.0 is Sugar 3.0! There the score was 12 to 10 in favor of Sugar 5.0.

good results for Sugar, Our thanks to Marco Zorbinati, to share in their ideas, free, big hug ..

What i love in sugar is the AVX compile, it makes AMD shines over popcnt

Thank you very much!

Can we also get a sugar 5 src that can be compiled into a linux? I use shell to run my engine since my machine is hella slow.

SRC always equal, compile according to the operating system

im having this error when i compile sugar in linux



But when i compile the original stockfish 5 theres no error
Im using  make profile-build ARCH=x86-64-modern

Short match at 2' a game, i7 running 8 logical processors.

Salt came out on top, 14.5 to 11.5 +4 =21 -1

Too close to make a final determination but perhaps enough to suspect a tendency.

Ran a 24 game 2' a game between SugaR 5.0 and Shark 150125;

SugaR edged out Shark 12.5 to 11.5
+2 =21 -1

i7 running 8 logical cores. Obviously they are very close in strength. I noticed their evaluations were usually nearly identical and their nodes were similar too. I guess this should be expected since they are nearly identical programs.

On my computer, SugaR 5.0 is still unbeaten in these matches, 9 different ones in all.

try..
make -f MakeFile profile-build ARCH=x86-64-modern COMP=mingw

(But when i compile the original stockfish 5 theres no error)
Original has no function Large Pages
Malloc is special file for LP
I own only Windows systems I'm sorry I can not help

Dear Marco,

Just wanted to let you know I'm ready now.

Oh. Ready for what, you ask?

Well SugaR 5.1 of course! Anytime you're ready!

Sincerely,
one of your biggest fans,
David

Thankyou

Marco's latest gift to us! Super strong engine and in testing so far, outstanding results. Sedat shows it at the top of the list after 1,000 game test.

I've run some short matches against Stockfish 6, The most recent Shark, Orka and the rest of my strongest engines. SugaR 5.1 won every match... 10 for 10! These were generally 24 games on my i7, 8 logical cores, in fast games. (Game in 3') (Some were Game 3' + 1" bonus) (A few were 2' +2") I should run some longer matches but was anxious to get some results right away.

Big thanks Marco and of course, the proverbial Big Hug.
