Sugar: new UCI engine based on Stockfish

Sugar is a new free UCI chess engine based on Stockfish.
Author: Marco Zerbinati


The development of Sugar and very bitter, I'm not an expert in programming, are simply passionate, self-taught, I will try in time to make it as different as possible from Stockfish, although it will always be a derivative

Hi all,

Can any one tell me what i do for Bmi2 compile in MZ or Sugar Code?

It serves processor system Haswell

Use Notepad++

Add

misc.cpp

ss << (Is64Bit ? " x64" : "")
    << (HasPext ? " AVX2" : UseAVX ? " AVX2" : "")
    << (HasPext ? " BMI2" : (HasPopCnt ? " SSE4.2" : ""))
    << (to_uci  ? "\nid author ": " by ")
    << "Tord Romstad, Marco Costalba and Joona Kiiski";

types.h

#ifdef USE_AVX2
const bool UseAVX2 = true;
#else
const bool UseAVX2 = false;
#endif


Makefile

### 3.9 popcnt
ifeq ($(popcnt),yes)
ifeq ($(comp),icc)
CXXFLAGS += -msse3 -DUSE_POPCNT
else
CXXFLAGS += -msse3 -mpopcnt -DUSE_POPCNT -mavx -DUSE_AVX
endif
endif


MinGW
line command

make -f MakeFile profile-build ARCH=x86-64-bmi2 COMP=mingw

is it necessary to compile it minGW can i compile it through Byo with your MZ.bat

if you use software BYO not need to modify Makefile

Marco,

I'm hoping you are planning on releasing the new Sugar soon. I've seen some of the testing results mentioned on the Immortal Chess Forum and the new version, 5.0 looks very impressive. They've been holding up my application over there for some reason, otherwise I would have replied to you there on a more current thread.

I hope you see this because there are others who also have been unable to post there and have wanted to let you know there are active fans of Sugar who are excited about the new version.

Many thanks Amos, Sugar is the best! Excellent job

Hello ! I have problem - engine no load http://prntscr.com/63dpw2 . This is all version gen, old and sse. I download engine from both links but same problem. Win 7, 32 bit. Please help me. Thank you !

I had a problem loading popcount 64 bit version but the 64 bit only version loaded without problem. Did not load 32 bit version

Marco,

Very impressive results so far. Thank you for your work and for sharing! On my i7 Haswell 4 core, no engine is better and I haven't seen overall results against other engines to be this one sided. Wow!

Where are you seeing results ? Thanks

Tomfl.

I've been running some quick engine matches at home.
1) Sugar 5 beat Stockfish 5 12.5 to 5.5 (2' games) while Stockfish 6 beat Stockfish 5 12.5 - 8.5 a smaller margin.
2) Beat Stockfish 6 080215 12.5 to 11.5 (2' games)
3) Beat Stockfish 6 080215 13.0 to 12.0 (4' games)

Admittedly those are close results but look who the winner was every time.


That is all I've had time for. There are other results ELSEWHERE but I don't want to get in trouble with the moderators. What I saw there was consistent victories for Sugar 5.0 and from my results, I don't think those results were invented.
