Android UCI engine update: Cfish 2017.02.07.ACH

Alexei Chernakoff has compiled Cfish too after Stockfish development version. Once again, arm8 build delivers the same nps as the arm7 build, which is the sign of a compiler option misused or somehow missed because one would expect %30 boost from 32 to 64-bit.

Nevertheless, all builds work fine on my MTK6752. Alexei deserves our appreciation for his efforts.

Android UCI engine update: Stockfish dev't 2017.02.11.ACH

Alexei Chernakoff's successful attempt to prepare engine builds for Android is good news for mobile chess fans, bearing in mind Jim Ablett's fruitful return which quickly turned to a long break and Aprijal Pasaribu's determined but time-limited passion for compiling.

Alexei's first choice of engine is not surprising at all. He began with a current development version of Stockfish. Although the arm8 binary seems not taking all the juice out of the 64-bit instructions, all his builds are working well with my devices so far and arm7 build performs fast enough to me.

Now all i have to say loudly is "Go Alexei Go!" because there are dozens of other engines waiting to be conqueered, indeed.

This build of Cfish is bundled with Other (Stockfish) Engines app by Javier. In case you want to install it directly under your favorite GUI without using OEX functionality, you can use THIS binary prepared for arm7 pie devices.

As a complementary useless information, let me remind that Cfish is probably the strongest Stockfish version available by definition because the same source is recoded using C instructions instead of C++. You may expect from 15 to 25 ELO more over an official Stockfish build of the same date.

CEPA 0.5.3 by Javiolo

Javier choosed to release engine binaries in separate apps designed to comply with the OEX format. Therefore, the latest release of CEPA is featuring several improvements on the main GUI features but don't expect anything about engine builds. He's recommending the installation of the Stockfish engine through the OEX installer that he updates regularly.

I think such procedure is quite logical and effective.

WHAT'S NEW (v0.5.3 of 3-Feb-17)
- Change Engines, Oex Engines and Analysis Revised
- Support Android 7
- Sound and Increment to probe no free
- fixed bug Android 2.2 Froyo
- fixed other bugs and corrections
