Android UCI engine update: Sayuri 2016.02.11

While Jim Ablett remains curiously silent on the web since a while, porting chess engines to Android as well as Windows has become an occasional task of the programmers. Only a few of them care about Android and others simply ignore the mobiles.

Cheese was the first to come by the programmer, oh wait, the second actually. It seems i've missed the update of Sayuri for even longer than Cheese. Thanks to a notification sent to the blog by "York" i woke up and downloaded the new version of Sayuri, compiled for Android by Hironori Ishibashi, the author.

The native binary is made for arm5 and it's the biggest build ever, exceeding 5 MB in size!

As my two Exynos 4412 devices are both taken by Komodo 9.42 gauntlets, i had to test it on my Galaxy Note I (not II) on the old dual core Exynos. Well, it worked okay, running at a very modest 90 kNps.

It's unknown yet the impact of the different compiling tools over the improvements integrated into the code. So, i plan to conduct a head-to-head test against the previous JA compile before introducing the new one into Rapidroid.

Those interested in testing the new version can download the binary mercilessly zipped to 650KB: HERE

RAPIDROID RELOADED: April-2016 v2 (Goodbye Komodo 9.3)

If you were to ask "Why a second list so soon without Komodo 9.42?", you would be absolutely right.

..and if i was to answer "Komodo 9.3 played its last round, so it's time to record the last moment", i wouldn't be absolutely wrong.

So, we'd better consider this one, the definitive April-2016 ranking.

The highlights of this release:

* Nothing but 898 games added

* Last release to include Komodo 9.3

Targets for next release:

* Update Komodo 9.3 to 9.42

* Update Cheese 1.7 to 1.8

* Introduce Excalibur LCD Express

* Introduce Senior Chess 1.81

Hawk Chess updated to 1.4.5

Though still not the suitable GUI for the tester, Hawk is a must have app if the priority is to play online games or automatically analyze games move by move with a favorite UCI engine and with graphically displayed output.

This update features:
* Improved board layout.
* Additional piece sets.

The app is paid and available HERE but there's a free trial option too with limited number of feature.

The biggest lacks of Hawk are the missing UCI options and the engine tournament feature which needs some more work for stability.

Android UCI engine update: Cheese 1.8

I must have forgotten that Patrice Duhamel, the author of Cheese, is releasing Android versions of his engine since v1.7. That's why i didn't wake up quick to go check his website when i've seen the update in chess forums. I should do this on 19th of March...

The new version promises important improvements such as:

* fixed problem in game phase update

* fixed crash with 1 Mb hash table

* fixed nodes count output

* fixed problem in multipv output

* add FRC support

* use LMR in PV nodes

* add "reverse futility pruning"

* add checking moves in 1st ply of quiescence search

* skip minor promotions in quiescence search

* remove mate condition in null moves pruning

* rewrite FEN parsing

* reorganize code for eval,movegen,endgame,protocols

* optimize move sorting

Latest and not yet released Rapidroid ranking places Cheese 1.7 at 2528 ELO. To find out whether the new version can jump to 2600, we must stay tuned for May-2016 list.

Tranaslation: Once again, 19 gauntlets of 300+ total games to replay. Uhm, puff, huh...

Android UCI engine update: Komodo 9.42

The quest for the perfect chess engine is not slowing down. Soon after the release of  9.4, followed by buggy 9.41 and bugfixed 9.42, the latest version of the commercial fleet leader is now ported to Android, as promised by Mark Lefler of the Komodo team in a forum post.

There's nothing clear yet for me to speculate about the improvement over the disappointing 9.3 but i must admit i've got high hopes this time. We'll soon see about this, no later than May-2016 release of Rapidroid ranking.

In contrast to rating lists based on Windows, Komodo 9.3 Android had performed bad, way behind its unique rival Stockfish-7, by a huge 70 ELO. The gap couldn't be explained by the default contempt of 10. It was exactly the same default setting with Komodo 9.2.

Remembering that Komodo 9.2 was the previous leader ahead of Stockfish 6 until TCEC-8 after which both engines have been updated for Windows and Android afterwards, Komodo 9.3 has quickly become a bad memory that a better version must erase.

I hope 9.42 will do exactly what's expected.

Komodo 9.42 for Android is a free update for owners of  previous 9.X owners. Otherwise if you want to try it for the first time, don't waste your time for a completely free solution. It doesn't exist. As the price is reasonable, just buy it at GOOGLE PLAY.

In case you feel doubtful of another unexpected regression, you may backup your current version with Titanium Backup before downloading the update, so that if anything bad occurs, you have the option to revert back later on.

Don't forget: Once upgraded via Google Play, you can't install any previous 9.X version with regular methods. So, only Titanium can help for a downgrade.

RAPIDROID RELOADED: April-2016

For the first time since months, a Rapidroid release comes with no further updates to be introduced. Jim Ablett remained quiet lately. Besides, there have been only a few engine updates waiting in the queue to be ported to Android. Looks like it's a good opportunity for improving further with a new full round now.

I hope May-2016 release will welcome some more non-Android engines for more colors in the big picture.

Thanks to the revision of previous groupings in the database, below release does not only include updated engines but also hundreds of replayed games in order to reduce overall average gaps vs opponents. The draw ratio is now higher than before up to 26.2% even with less games. It's a good sign which indicates Rapidroid gets more accurate.

Please note that i've added a column to the list to indicate what time controls each engine can play. 

There are three types here: bf, b and f. 

"b" refers to blitz (meaning Fischer clock)

"f" refers to analyze mode or fixed time per move.

"bf" refers to compatibility with both.

As not all engines can use both, the experiment gets complex to maintain because each division may require two sub-tourneys under different time controls, which must be joined at the end. That also explains why the number of games can't be the same for all engines, even though i try hard to avoid gaps.

I still believe it's worth the effort. It's the only method to compare the strength of the engines which can never play each other.

The highlights of this release:

* UPDATED Arasan 18.2 to 18.3

* UPDATED Rodent 1.7 to II 0.8.7

* UPDATED Tucano 5.00 to 6.00

* DELETED Clubfoot for frequent early terminations

* DELETED Mini Rodent due to similarity with Rodent II

Rapidroid is calibrated using CCRL 40/4 ratings of 40 engines, converted to Exynos 4412, assuming that the latter performs 65 and 110 ELO lower than 32 and 64 bit engines of CCRL respectively.

Targets for next release:
* Introduce Excalibur LCD Express
* Introduce Senior Chess 1.81
