Android UCI engine update: Cfish 2017.09.09.ACH

Cfish builds for Android come more frequently than Stockfish. This time i wanna go simple and share all the latest builds in one post. Thanks to Alexei for compiling these.

The latest:
GET Cfish 2017.09.09.ACH (original Ronald de Man code) for arm7 and arm8
GET Cfish 2017.09.09.ACH (patch )for arm7 and arm8

If you wonder why two builds come with the same datestamp, here's the answer by RomeoA23:
CFish_RDM = CFish from Ronald's original sources - Updated to "Extend ShelterWeakness array by dimension isKingFile"
My CFish based on green patch (on that moment) - shelter2 (tweak ShelterWeakness after re-tuning)
They are almost identical, but not quite: SF team added some changes to the patch without testing (again!)

Android UCI engine update: Ethereal 8.27

Andy Grant has released Ethereal 8.27 on Sep,6th. Since his releases came faster during summer time, it appeared that some older versions were skipped. They are now shared below.

I expect 8.27 gets close to 2600 ELO. For the moment, 8.23 is playing in Rapidroid.

The latest as of today:
GET Ethereal 8.27.AG for arm7 32-bit pie

Previous versions i've never shared here:

RAPIDROID RELOADED: September-2017 games database

Although i would NOT suggest that games played at 900+1 TC on a smartphone can represent a remarkable quality of chess, i'm sharing HERE a full archive of all games used to calculate the latest Rapidroid ranking, as per request.

All evals and depths are recorded in the pgn's, so it's possible to make comparisons across devices.

Note that the 7z archive is quite big: 22.2 MB!

RAPIDROID RELOADED: September-2017 ft Komodo 11.01 and Vajolet 2.3.1

Komodo 11.01 regains pace to chase SF8 closer but the top stayed the same as of September-2017. We'll have to expect Komodo 11.2.2 overcomes SF8 before introducing a SF development version.

Vajolet is the strongest new entry of this release, above 3000 ELO. It brings some fresh air and gets 15th place in the list.

From April to the end of August, Rapidroid has seen 2/3 of the games replayed due to the strict promotion & relegation procedure. Below list is the outcome of 20 rounds played by 11 groups with some manual games added.

Despite the high ratio of refreshment in the database, the results appear to stick around similar ELOs and they lie within error margins. That's what makes me think the whole structure of Rapidroid is reliable since the results are reproduceable.

The highlights of this release:
* ADDED Galjoen_v0.35.6 (1970 ELO)
* ADDED Marvin 2.0.0 (2241 ELO)
* ADDED RuyDos 1.0.3 (2520 ELO)
* ADDED Tiny Chess 1.4.6 (2099 ELO)
* ADDED Vajolet2 2.3.1 AP (3006 ELO!)
* UPDATED Cheese 1.8 to 1.9
* UPDATED Ethereal 8.05 to 8.16
* UPDATED Gull 3r5.JA to 3.AP
* UPDATED Komodo 10.3 to 11.01
* UPDATED Rodent II 0.9.68 to III.0.171 (Multicore!)
* UPDATED Sting SF 7.3 to 8.1
* UPDATED Texel 1.07a6 to 1.07a9lazy
* UPDATED Zurichess Jura to Luzern

Targets for next release:
* UPDATE Danasah 6.1 to 6.5
* UPDATE Ethereal 8.16 to 8.23
* UPDATE Komodo 11.01 to 11.2.2

The build by Alexei Chernakoff doesn't include an exact date. Besides, a quick search yielded nothing about a new release of Matefinder. I assume labeling it Aug,31th isn't a big mistake.

If so, let me know and i will correct the date.

Android UCI engine update: armFish 2017.08.27

The "fastest fish by theory" was updated by Lyudmil Antonov on Aug,27th.

Note that armFish builds are made for arm8 64-bit devices only and that asmFish is another story concerning 64-bit x86 devices, be it PC's or tablets.

By the way, i've read some posts claiming that some Cfish builds showed faster in some devices. I guess these are related to hardware differences because the lower the level of programming, the bigger the incompatibility problems.

That's why C and C+ had come out in the past to ensure multi platform portability and save time for developers.

Android UCI engine update: Demolito 2017.08.26 for arm8

If you know Doublecheck and Discocheck engines, you must be familiar with Lucas Braesch's contribution to chess engines development. Since the beginning of this year, he went on to write a new engine from scratch, taking small parts of Discocheck.

Although he'd written he wouldn't be interested in delivering executables in order to better concentrate on the code, some builds are already out for testing.

One of them is made by Lucas himself and it will only work with 64-bit devices. So, meet the son of Discocheck.

New Android UCI engine: armFish 2017.08.XX

Androiders, especially the users of ARM cpu's must thank Lyudmil Antonov for making the mighty assembly port of Stockfish available for arm cpu's. Assembly builds must run the fastest possible by definition, even faster than Cfish.

It was indeed a hard task bearing in mind that even porting C++ code to Android requires a lot of knowledge about the software to be used to compile and also a good practice of several Windows and Android libraries.

Working with assembly code is even more difficult because of the primitive level of the language.  It's the least human environment for a programmer. The only reason to prefer the native assembly can be nothing but speed, which is the exact case of a chess engine. Congrats to LA for succeeding in this insane mission!

There are many builds LA released so far. You can find links to each of them below. The recent ones come with Syzygy tablebase support as well. Yummy!

The only bad news about armFish is that the builds are made for arm8 64-bit devices only.
