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

CEPA 0.4.4 is out

CEPA is and will remain interesting as long as it comes with bundled Stockfish builds. I hope it will present arm8 builds too in the future. For the moment, the new two versions 0.4.3 and 0.4.4 both come with the latest Stockfish builds based on the code of September 25th. As there were no significant update notes about 0.4.4, i assume it's made to complete the missing nopie builds of Stockfish.

An important note for Javiolo, the developer, is that arm5 (supposed to be arm5.pie) version didn't work on my 64bit Lollipop phone. It seems this one is not pie compatible and it has the exact checksum of the nopie version. Probably it's a packing error. But it doesn't matter at all, given that there should be no arm5 device running on Lollipop and beyond. In case you know such config is available somewhere, let me know.

Download and enjoy CEPA update HERE at Google Play.

Chess 8.8.3 by Jeroen Carolus

There are several apps called Chess in Google Play and this "original" name is so frequently used that sometimes my mind is confused while trying to remember which "Chess" is from which developer.

Um, today is my lucky day and i remember that this one is written by Jeroen Carolus. It's quite an old app that i know since almost 3 years. But it's maintained and improved regularly by the author.

The main attractions of "Chess" is the UCI engine import feature, FICS online play and especially the Chess960 aka Fischer random chess compatibility.

Take a look and decide for yourself: HERE at Google Play. 

Yet another chess app for Android: Metal Chess

A new app which looks tiny and simple, based on GreKo 12.9 engine (~2450 ELO). I think it will only appeal to casual players because i didn't see any clock settings in the screenshots but only a difficulty setting. My basic rule of thumb is CLOCKS = SERIOUS APP.

Thanks to Mhoadiev de la Paz for sharing info about Metal Chess. Although i won't install it, i guess some others may be interested. So HERE's the Google Play link to this app.

Chess Free by AI Factory Ltd updated to 2.44

Another update i won't forget to share just because i'm a few weeks late. Nothing changes in terms of engine strength. Only a cloudy fix that i wouldn't call necessary, at least for me. I don't like clouds too much, i'd rather prefer a sunny sky.  

WHAT'S NEW:
* Updates/fixes to Google Play Games cloud saving

Download: HERE at Google Play

Senior Chess 1.83 by Leen Ammeraal

This is an update i'm sharing two weeks late. Leen Ammeraal released it on 12th of September actually. Let's blame the delay on the job duties, a sweaty sweet trouble which pays me for the time.

What's new:
Version 1.83: Illegal moves sometimes occurred when the chosen level was 0s per move for the computer. Again, this was reported by Mr. Bakkouz. In this new version such illegal moves should no longer occur.

Perfect 2016 opening book for engine testers

Sedat Canbaz has recently released the 2016 version of his wonderful engine book Perfect. I guess many chess engine users will enjoy using the update which integrates too many improvements over 2015 version. Thanks to Sedat for such dedicated work.
As usual, the 7z archive contains the book in different file formats used by Arena, ChessBase and Shredder GUI's.

You can download Perfect-2016 HERE

Android UCI engine update: Stockfish dev't 2016.09.17

Here's another release of Stockfish builds compiled by Peter Ă–sterlund. Probably the strongest mobile engine ever. My task: Sharing. Your task: Enjoying. Meanwhile thanks go to Peter.

RAPIDROID RELOADED: September-2016 with Komodo on top

Rapidroid has delayed more than expected at the end of August. Ooops it's already the middle of September. However, getting back the second Galaxy N7100 to work for Rapidroid has helped me speed up the tourneys and more than 5750 games have been played. Now we have only 5 more rounds to replay in order to refresh the whole experiment with accurate time control implementation.

After achieveing this goal, i won't go beyond 20 rounds and stay at max 400 games per engine. So all that remains to do will be nothing but integrating updated engines and finally allocate more time to manual games. Seriously, i can't wait to see how will perform standalone programs like Chess Genius, Mobialia, Senior Chess, Chess Free AI etc. vs UCI/XB engines.

Komodo 10 stayed at the top of this release, ahead of Stockfish. After analyzing the games they played, i've concluded that Komodo manages to avoid draws better than Stockfish against some specific weaker engines, especially Critter. Although Stockfish is slightly stronger than Komodo 10 when they play each other, performance vs other engines seem to be the deciding factor up to now.

The highlights of this release:
* UPDATED Zurichess Geneva to Graubuenden
* SKIPPED Arasan 19.0.1 update due to bad perfo vs 18.3

Targets for next release:
* Finish rounds 15 to 17 out of 19.

SSDF Computer Rating List of 2016-08-03

Everytime i get deeply concentrated on something important, i may forget something else also important. TCEC, Rapidroid, job duties, family issues in August...

In the heat of the summer, i must have skipped the release of the the new SSDF list, at least i forgot to share it here. After decades, the oldest of all computer based rankings is still alive thanks to Lars Sandin.

If the latest Stockfish and Komodo versions are absent, that doesn't matter too much to me because a lot of mobile programs and tabletop computers are still ranked under rarely found time consuming conditions close enough to human chess tournaments like:
* TC of 40/120+20/60
* Ponder on
* Own opening books

The full list and comments are available on SSDF website: HERE

Senior Chess 1.82 is out

Senior Chess is written by Leen Ammeraal from Netherlands. It's relatively an old app but it never stopped progressing since years. The latest update to 1.82 is now available at GOOGLE PLAY.

If you've never used Senior Chess, note that you will like its ease of use especially. It has a clean and readable layout without complicated menus. It's simply a suitable mate for any chess player above average.

Regarding the strength, it's not a monster for sure. I never had the opportunity to play manual games vs UCI engines we know from Rapidroid. I would guess something between 1800 and 2000 ELO.

Android UCI engine update: Ethereal 7.78

Thanks to immediate reaction by the author Andy Grant, the latest update of Ethereal has finally become compatible with all (most probably) arm devices. Previous build had problems to run on most devices in despite of a few exceptions.

Ethereal is progressing quickly in terms of ELO strength. Taking into account it has neither SMP nor hash tables yet, there's significant potential ahead. Go Andy go!
