Android UCI engine update: Stockfish Dev 2015-10-08 JA

In parallel to TCEC-8 progressing stage by stage until an unexpected result, every stage becomes a pool on speculations whether Stockfish can take back the crown from Komodo.

No doubt, the head-to-head race makes the development compiles attracting. People are insterested to test new versions each and every day before the official update comes. Unstoppable incredible hunger...

Some days ago, we have seen 2015-09-07 version of Stockfish compiled by Peter Österlund. It's in my repository available for the most hungry ones :-)

After a little while, it's now too old as Jim Ablett compiled another dev't version dated 2015-10-08. This one is interesting because we have an arm7 compile from JA for the first time.

Remembering that a previous close tourney between Stockfish compiles revealed that JA compiles perform very well, the arm7 compile from JA might deserve attention.

If i have enough spare time remaining from endless working hours, i want to play another close tourney between Stockfish 6 official, dev 2015-09-07 and dev 2015-10-08.

Or should i push back my appetite and remain patient until Stockfish 7 official release comes?

New Android UCI engine: Laser 0.2 beta JA

Put your laser lights on! This one makes yet another Android engine. The fleet keep growing and my smile gets more visible.

Welcome then Laser 0.2, written by Jeffery An, compiled by Jim Ablett.

To use it with Chess for Android, don't forget to follow the uci2xb procedure and don't rename the ini file. You may use ini file settings however.

Download it: HERE

Android XB engine update: Chenard 2015.08.15 JA

Chenard, currently one of a few stable and trustable XB engines under 2000 ELO, just got an update over the previous version of July 2014.

I just can't wait to check and see how forward the gameplay has stepped.

Please note that the filename is based on the source code update date in the download link below, not the date of the compile as used by Jim Ablett. However the binary is the same: Commit number 5102f59f52

Download Chenard: HERE

Android UCI engine update: Bitfoot 15.09.22 JA

Bitfoot is the bitboard version of Clubfoot engine. Almost 200 ELO gap proves that the bitboards lead to stronger play.

Below binary compiled by Jim Ablett is based on the source code of September 22th. I've prefered to rename it according to the commit date instead of Jim's Oct 10th. This is always the same binary and the unique code of the source is d9aeb437d6 in github.

Enough said, HERE is the Android binary to download and try.

Android UCI engine update: Clubfoot 15.09.07 JA

Clubfoot is approximately 200 ELO wekaer than its big bro Bitfoot. However, its development is ongoing. Now, we have now a recent compile for Android based on the source code dated Sep,7th.

Once again, i've renamed the engine binary using the commit date instead of the compile date used by Jim Ablett. The exact commit number of the source is 048995de70.

Please note that Clubfoot only played fixed time per move games in Rapidroid. In case the new version plays Fischer clock games without problem it will become a passepartout engine and will use both time controls. That means the oppoonent portfolio will be enlarged and the accuracy will increase.

Download the new Clubfoot: HERE

Android UCI engine update: Sayuri 2015-10-01 JA

Another engine i could not succeed to run flawlessly in my Rapidroid experiment used to be Sayuri. It's a medium strength engine which is frequemtly updated by its author Hironori Ishibashi.

What makes Sayuri special to me is its ability to use multi threads. I'll be glad to recall it for duty and get it rated soon whenever the compatibility tests are okay.

Jim Ablett named binary according to his compiling date but i've choosen to rename it using the commit date of the source. It doesn't matter anyway unless nobody else compiles Sayuri. Let's note that the commit number is exactly 2b47cdd70a.

Download Sayuri for Android: HERE

Android UCI/XB engine update: GreKo 13.1 JA

Although i'm stuck on v12.5 in Rapidroid, GreKo is updated to 13.1 for Andoid by Jim Ablett. Previous 12.6 and 12.8 compiles were hanging randomly during my engine tournaments. I wish 13.1 doesn't repeat this, so that i can rate the most recent one.

Under Android, use GreKo only in Winboard protocol mode. Therefore only with Chess for Android, since it's the sole GUI compatible with it.

Usage of the ini file and the book is not mandatory. However, the ini file works and can allow selecting higher hash sizes at least.

Downlaod GreKo 13.1: HERE

Android UCI engine update: Protector 1.9.0 TCEC JA

Protector is no joke at all. It's one of the leading engines and it's capable to beat monsters like Houdini 4. TCEC-8 is the proof!

Unfortunately, i could not rank the previous Android compile 1.8.0 for frequent bad termination issues. I hope that new compile heals the problem.

To use Protector under Droidfish, use the UCI engine directly and for Chess for Android, follow the uci2xb method explained previously.

Download and try Protector 1.9.0 TCEC for Android: HERE

New Android UCI engine: Mchess2 1.02.00

Mchess2 is a UCI compatible chess engine written by Michael Jorgensen from Denmark. I have no idea yet how strong it is. Probably not too much at this step but even under 1500 ELO, i'll be happy to include it in Rapidroid in case it works without problem sşnce an accurate rating list needs engines from any ELO range, especially balanced among all ranges.

You can download a compile made by Jim Ablett HERE and give a try on your Android device.

Android UCI engine update: Gunborg 1.39.JA

Gunborg 1.0 is updated to 1.39. Thanks to Jim Ablett we have now a recent version in hand.

The working structure is the same: If you want to use it with Droidfish, the engine itself is OK. If you prefer Chess for Android, proceed the uci2xb method and avoid renaming the ini file.

Download Gunborg 1.39.JA: HERE

Android UCI/XB engine update: Galjoen 0.30.2.JA

Galjoen just got an update compiled by Jim Ablett for Android. I remember that the previous one had issues with Fischer clock and it could not play fixed time per move either, using too much time beyond toleration. Therefore, it wasn't certified for Rapidroid.

Now it seems things changed. The updated version, after the first two games where it faced the native engine of Chess for Android is confirmed OK for Fischer clock.

Fixed time per move on the other hand is still open to speculation. It started by using 16 seconds vs 15 selected but with every further move the usage increased constantly up to 20 seconds. I didn't yet decide whether i should certify it for that time setting or not.

Probably it's wise to avoid tolerating excess time usage beyond 10%. We'll see.

The engine doesn't look strong yet, It won above mentioned match by 1.5 to 0.5, meaning that it plays way below 2000 ELO, maybe around 1600.

Android UCI engine update: Stockfish Dev 2015-09-10 (towards Stockfish 7)

Each hot championship is a source for new public demands. Since TCEC-8 has started last month, chess freaks didn't stop asking for a new release of Stockfish. Version 6 was released months ago and development version have already progressed a lot, although it's not yet considered enough to release an official update.

On the other side on the medallion, Komodo 9.2 has already fulfilled the expectations so far during TCEC-8. The reptile currently leads the Stage-2 ahead of the fish, somehow making me smile because i still remember the speculations stating that TCEC had to be delayed by the organisers just to make sure a recent version of Komodo stronger enough to cope with the latest Stockfish version becomes available.

Be it true or not, the tournament is in place, running at full speed and i'm not too concerned about possible commercial timings and manipulations. Both teams deserve respect, no matter the status, commercial or open source.

Computer chess can't progress without competition after all. Besides, i wish there could be more candidates to chase the leaders. Unfortunately there's only two engines and all others following far behind. Isn't it sad to see Houdini 4 still playing for 3rd place after so long time?

Regarding Android side of the two musqueeters on top, Komodo 9.2 is already available while Stockfish-6 was the latest among the fishes, until i heard of an alternative development version compiled by Peter Österlund, the author of Droidfish and his own engine Texel.

I see no reason for that development version play weaker than v6, given that Peter's previous compiles performed very well and that it's based on arm7 or 8 already.

I will schedule a head-to-head match between that dev't version and v6 to see what's the gap as soon as i can. Rapidroid ranking will wait for an official release anyway, regardless of the result.

Meanwhile you may download the package which includes all possible versions compiled and test for yourself: HERE

Schachcomputer.info rocks!

If i suggest people to check out Rapidroid for many programs based on Android, i would recommend Scachcomputer.info for any kind of information related to table top chess computers, from the oldest one to the most recent.

This is a very old network of dedicated chess computer freaks, mainly from Germany, establishing tourneys and games between their computers since years, online or over the board. A great dedication i admire a lot!

Their two rating lists are based on tournament time controls and also rapid chess which they call Activschach for speed chess. FIDE had forgotten long ago that speed chess term but it still counts for computer chess, using 30 seconds per move.

One thing to keep in mind is that they never include any engine other than those installed inside a touchable, dedicated chess unit! That's the main reason there's nothing like 3000+ ELO in there.

The lists are comparable to SSDF in terms of calibration, therefore they should reflect traces of human vs machine games of the past. Similarity with FIDE scale is no surprise either.

For a very detailed forum and a trustable ranking, don't forget to:

1) Bookmark the link of THEIR WEBSITE

2) Take a look at the latest rating list releases based on SPEED CHESS and TOURNAMENT TIME CONTROLS.

RAPIDROID RELOADED: September-2015 with Komodo 9.2

Although this release took a few days of delay, it was just because of a hard working week. Anyway, i believe the improvements compensate largely.

The highlights of this release are:

* UPDATED Komodo 9.1 to Komodo 9.2

* UPDATED Zurichess Basel to Zurichess Fribourg

* ADDED Fridolin 2.0.0

* ADDED Rybka 2.3.2a MP as new Windows engine

* ADDED The King 3.50 x64 as new Windows engine

* ADDED Novag Secondo as first tabletop computer engine

* ADDED 50 ELO to all Android engines for better calibration

THE TOPPER:

Komodo 9.2 is clearly stronger than 9.1, in contrast to my initial expectations. After a short hesitation, i replayed all previous Komodo games and 9.2 proved itself. It seems the reptile will stick to the top for a while, at least until Stockfish 7 kicks in.

As mentioned previously, the list needs good calibration vs CCRL and SSDF to be as readable as possible. I always knew it's very complex without the same hardware configuration for Windows engines and use them as trustable calibers.

AMD Athlon x2 4600+ used by CCRL and Intel Quad Core Q6600 used by SSDF have both disappeared. The only solution remaining is to find an acceptable correlation between my Intel Core i7-620M, which has also disappeared from the market long ago.

Past comparisons in benchmarking sites and some available tools show that i7-620M performs better than Athlon and slightly lower than Q6600 with MP. Therefore Windows engines must collect as much ELO as in CCRL but not more than SSDF when tested against Android engines, simply and logically.

Remote connection feature of Chess for Android worked well between Samsung Galaxy Note II and my notebook except for the gauntlets. No way to run like this.

I've had to alter my pairing method to increase automation, by playing vs each Android opponent one by one in separate gauntlets using a collection of related openings instead of consecutive rounds with various opponents using same opening for whole round.

The network engine feature works okay but needs improvement to become more effective. That's a topic i'll come back to in details in a future post.

WINDOWS CALIBERS:

Both Rybka and The King seemed to have some flaws in the calibration task:

Rybka uses hypertrading in MP mode. HT divides each physical core to two logical threads and virtually doubles the total number of threads. Unfortunately, the increase in nodes per seconds doesn't deliver the expected strength increase. HT is not efficient when used with chess engines. I've chosen to tolerate the efficiency loss in Rybka case and keep following because on my notebook there's no option to disable HT via BIOS.

The second caliber is The King. It works well under Arena as a Winboard engine via KingUCI.exe which acts as wb2uci interface. Threads and hash are selectable via wb2uci.eng but strangely the engine hogs the CPU for no reason unless i run it with only 1 thread ouf 4 available. When i use all 4 threads, 3 of them stay loaded after King makes its move. I made sure it's not because of pondering because Fritzmark running in parallel hits the usual score. There must be something wrong keeping the "freed" threads busy. Since it's not comfortable to hear the cooling all the time, relying on 1 CPU rating of CCRL looks better. However, i suspect 1 thread out of 4 on my notebook is not exactly the same as 1 core out 2. It should be something between 0.5 to 1 CPU.

Finally, i've decided to add 50 ELO to all Android engines. Rybka and The King are both ranked well within acceptable error margins for the moment.

In next steps, i'll need some single thread Windows engines to bypass the hyperthreading effect and compare better with other rankings.

SWEET MEMORIES:

If one wonders why Novag Secondo is in the list as one the weakest dedicated chess computers ever sold, i must state it's a very old friend to me. It was my first chess computer in 1993 and still works without problem in 2015!!!

So i could not keep myself from putting it into the pit after all these years. After all, my retro companion needs more weak opponents to move forward a little bit.
