Android UCI engine update: Sugar 2016.04.15 // ERRATUM

Sugar is one of the strongest Stockfish derivatives. I had previously shared 2015.04.15 version HERE. No doubt that it became quite older since.

Thanks to Alex, a new compile is available now. It's made for arm5 and probably loses some search speed compared to arm7. However, i guess it can reach 3250-3300 ELO.

GET Sugar 2016.04.15 for arm5 32-bit

POST SCRIPTUM / ERRATUM:

The posted binary appears to be exactly the same as the previously posted one. There's no new compile of Sugar other than 2015.04.16. So, all irrelevant information and files are deleted.

Only the logo remains. I prepared it today and won't delete it :-)

Meanwhile, the only build, still the latest one, benefits from a filename correction and becomes 2015.04.16 (instead of 050415) to correctly link with the source commit date and also to avoid misunderstandings related to date formats, a source of inaccuracy frequently observed with Stockfish development builds.

Lesson learned: DDMMYY and YYMMDD can be mind confusing. Always prefer YYYYMMDD!

I didn't find differences from the old version. Identification and the size are identical. Whom clones interest: in "google play" there is an old program "Professional Chess Free". It seems that it is DroidFish with advertizing, but behind a mask of Stockfish - "ChessPro 1.0" clone is hidden:https://cloud.mail.ru/public/4coD/j27BJrUJB I don't know: deception it or not.

Hmm, i've gotta check this about Sugar. The standalone Stockfish clones, i know all of them. They must not be taken into account.

I think, this Sugar is old, same size, same type of playing.
It is sad, i was hoping that, this is new version :((

From now, no more engines.

I check versions of old Stockfish and here that noted: 1) As I understand Stockfish 6.0.OR from the official site actually of pie version 2) nopie is in pbchess, it is possible to add 3) B CEPA is other assembly of Stockfish 3.0 too it is possible to add.

4 old gnuchess-5 version : https://cloud.mail.ru/public/3dWT/hgKbwMxfH

Yes. I will post all Stockfish 3.X 4.X 5.X 6.X and 7.X builds in dedicated posts, like i did for 2.X. Soon to come.

I decided to find a method of exact comparing of suspicious engines. With it I was helped by the program "DiffTool the File Compare Tool" + "DiffDroid" (extension for convenience). Sugar versions of 100% are identical. And here the clone of "ChessPro 1.0" differs from "Stockfish DD" on 15251 bytes or for 3,5%.

I usually compare with ES File Explorer. It can show MD5 checksums. Same checksum = Same checksum. I didn't do this control with Sugar in a hurry. And the ID label was concincing due to the date format.

"DiffTool... + DiffDroid" can be used easily from ES. And it seems to me that it gives more information. For clones it is possible to see not only total quantity of changes, but also to compare each byte. And respectively to understand: whether we deal with normal substitution of the name or essential changes are made to parameters of an engine. It I seemed to me very conveniently. But this my subjective judgement :)

Gurcan Uckardes said...

I'll try DiffTool but equality of MD5 checksum should be enough to confirm two builds are the same.

Tvé engines are absolutely identical. This is no change!
