Android UCI engine update: Stockfish dev't 2016.09.25

I don't know whether the current lack of engine updates is a seasonal effect or could it be that such silence is related to the ongoing TCEC fever that makes the authors concentrate on the tourney and delay the updates? Usually i don't blah-blah for nothing. Since weeks, we've only seen Stockfish development builds falling into the Android zone.

The latest update of Stockfish has just come from two different sources: First one is Aprijal Pasaribu, a visitor of Chesstroid, capable of creating engine binaries for Android arm7 and second is CEPA 0.4.4 update.

There's no 64 bit build available among these, only arm5, arm7 and x86 are ready to plug:
GET Stockfish 2016.09.25 for arm5 nopie bundled with CEPA 0.4.3
GET Stockfish 2016.09.25 for arm7 nopie bundled with CEPA 0.4.4
GET Stockfish 2016.09.25 for arm7.pie bundled with CEPA 0.4.3
GET Stockfish 2016.09.25 for x86.nopie bundled with CEPA 0.4.4
GET Stockfish 2016.09.25 for x86.pie bundled with CEPA 0.4.3
GET Stockfish 2016.09.25 for arm7.pie by Aprijal Pasaribu
GET Stockfish 2016.09.25 for arm7.pie PGO optimized by Aprijal Pasabiru

In case PGO version works well in your device, you can forget the regular version. PGO version is pure and faster by 4 to 6%.

Let me remind that CEPA builds are slower. I didn't test their playing performance and i just assume that more kNps means more ELO between builds based on the same source code.

Finally, those who want to learn more about the new engine cooker can visit Aprijal's blog HERE

Gurcan, have you checked Arasan from Aprijal? Under android 5, C4a , 1 sec per move, engine freeze, some times hangs.

No issues with 64bit Lollipop on MTK6752.

Not yet. Probably an adaptation on the source code is forgotten. Sometimes the code requires specific alignments beyond regular ones. JA faced that many times.

Update CEPA,new st 20160929!

Hi Gurcan, did you manage to run Laser 1.3 beta properly?

Unknown said...

Works with Polyglot but unfortunately i can't use more than 1 threads. Polyglot.ini setting is skipped by Xboard protocol. Looking for a trick currently. By the way, using 1 core it beat 0.2beta 16-4 in a 120+1 match. Around 2600 elo...
