Android UCI engine update: Zurichess Geneva

Zurichess keeps travelling through Switzerland. Latest station is Geneva and we've just received an Android version compiled by Jim Ablett. I guess it's an arm5 build but i'm not sure as the binary did not disclose any trace like previous ones.

Regarding the strength, some 30-50 ELO more may be expected according to the improvements mentioned by the author. I would be glad to test and verify this quickly but i'm too close to a new Rapidroid release including Fribourg version. That's why Geneva will be replacing Fribourg later on.

In the meantime, you may download and try Geneva: HERE

Fritz 15 powered by Vasik Rajlich: Coming on November, 25th

Most of the computer chess freaks were not yet born when Fritz 1.0 was released. After decades, the oldest trademarks in computer chess is about to come to 15th version.

In contrast to Arasan which is not only as ancient as Fritz but always maintained by the same author, Fritz has seen different authors behind the curtain.

The last version is powered by Vasik Rajlich who dominated an era with his famous Rybka until the so-long criticized ICGA act, after which Rajlich lost motivation and stayed away from the chess world for a while!

Now he's back on track and i hope the new probably "Rybkatized" Fritz will bring fresh air to the field.

Regarding the strength, if you were to force me to speculate, i would say it ahould be slightly better than Houdini but not as high as Komodo or Stockfish.

The bad news is that no Android port is in the schedule.

News from the Rapidroid labs

Unless there are new engines or updates, Rapidroid is a non-stop and unlimited tournament running by divisions, in up runners and down runners basis. There are basically 11 divisions of 9-10 or 11 engines in each and after each round 3 winners go up, 3 losers go down and the roulette turns again.

When there are newcomers to introduce or updates, things slow down and get complicated because the strict rule (Why the heck did i invent it?) tells "Only one version of each engine must be included".

That means any updated engine requires that all previously played games are removed and replayed with the new version. All related PGNs, as well as all previous rankings, graphs, stats etc. must be also updated.

This is exactly an erase and rewind scenario. I know it's hard to do when there are dozens of rounds already played but i'm sure the final result is the most trustable one without rating distortion.

In case of a new engine to introduce, it's still complicated because i have to find the correct division to introduce it without losing the balance between the number of players in each division. It may happen that no place is available in the most suitable division. In such case, the first or the last engine of that round must be ported to the neighbor divison. More and more games to replay!

The number of ECO lines played by each engine must be also monitored and kept well balanced to avoid the effects of sensibility to a given opening category. An engine should not always play ECO A for example.

After October-2014 release, i'm currently working on November rankings which will integrate below changes:

Arasan 18.1 will replace Arasan 18.0 (+20 ELO expected)

Cheng 4.39 arm5 will be replaced by arm7 (+30 ELO expected)

Deep Saros 2.3f arm7 will replace arm5 (+10 ELO expected)

Galjoen 0.31 will replace 0.30.2 (+30 ELO expected)

Maverick 1.5 Leiden will replace Maverick 1.0 (+60 ELO expected)

Floyd 0.6 will be added

Mini Rodent 1.0 will be added (Yes, it may distort for a while but that Mini and Rodent 1.7 will be both gone when Rodent 2 will step in)

Due to above updates, i delayed the introduction of the second dedicated computer Excalibur LCD Express. Hopefully noone would cry out for that :-)

Now, back to digging it deep!

Must have tools for chess with Android

Referring to an expression i like very much which says "Better be late than sorry", my status here is a little bit paradoxal because i must say: "I'm late and i'm sorry too".

In short, this post should come months before!

This is about three system utilities i always keep continously running in the background on all my Android devices during Rapidroid games.

Without these three muskeeters in place, i would feel blind and unsafe.

1) CpuTemp in Statusbar

This tool shows the cpu temperature in the status bar and not in the notifications panel like many others do. The temp info is crucial and it must be visible on the status bar because pulling down the panel to read the temp needs a touch on the screen which is risky for me when two engines play chess, especially if case the GUI is Chess for Android. You simpy don't want to interrupt a tournament accidentally!

Another nice option is three temperatıre thresholds in Fahrenheit or Celcius and relevant colors fully customizable.

The app is free HERE as a tiny module which requires the installation of Xposed Framework to work. You need luck too because not all processors are equipped with temp sensor (Rockchip for example) or the app may simply not be compatible with yours.

2) CpuStats

Monitoring the running state of the cpu cores is as vital as checking the temperature. Nothing else can tell you whether a multi core engine is really using the expected number of cores. Another issue it comes to help is when an engine refuses to stop and exit when requested by the GUI. This is dangerous for any testing environment as the faulty engine remains running in the background and hogs one core or more depending the config. Once this occurs, in the next automated game, a multicore engine may start running without one of the cores vs a single core engine. This is simply unfair.

CpuStats freely available at Google Play, will help you figure out something goes wrong by showing the load of each core on-the-fly, every x seconds. Once again, the icon is pinned on the status bar and NOT in the notifications panel.

If monitoring the state of the cores is not enough (it's not enough of course), the app will show the current frequency as well, in readable numbers, next to the cpu load icon. This feature is extremely useful in case too much temp forces your cpu to throttle and your engines to play weaker.

3) Memory Bar

If you think the temperature, the load and the frequency are enough, think again. What about the RAM usage when you try to allocate as much hash memory as possible to the engines? What about the memory eaten by tablebases? Monitoring current free RAM becomes even more crucial. That's where the third free tool, Memory Bar Simple comes to help. It has a nice icon to reside in the status bar showing the amount of free RAM in MB. Although it will show 999MB beyond 1GB free, that should not be a problem as we know enough free RAM is available for chess.

New Android UCI engine: Floyd 0.6 JA

Floyd is a new engine to Android but don't think it's the first attempt of a candidate chief cooker.

Marcel van Kervinck is highly experienced in programming, not only chess but other stuff too. Those who remember MSCP and Rookie, two older engines from the same author, should have already heard about Marcel.

Floyd 0.6 is still experimental, probably under 2000 ELO on Android. We'll see about that soon when it gets ranked in Rapidroid.

Those who don't wanna wait for ages for me to get it rated, can give a try now: HERE

Android UCI engine update: Cheng 4.39 JA for arm7

The most recent version of Martin Sedlak's Cheng was previously compiled by Jim Ablett for arm5 and posted here in parallel.

After finally getting equipped with an arm7 device, JA started to recompile for arm7, not only the latest development versions of Stockfish but also some other popular engines. Truth to be told, we are not against arm7, given that arm5 got too old already vs arm8-64bit, the latest instruction set.

Bearing in mind that 64-bit Android, namely Lollipop, is NOT the most compatible environment for handheld chess, i still suggest arm7 as the optimum unless a limited variety of arm8 compiles like Stockfish and Komodo will suit your needs. 

Thereafter, the last arm-7 gift from JA is Cheng. I hope this version will add some more fuel into the tank.

Android UCI engine update: Stockfish Dev 2015-11-09 JA

Without doubt, this one will make many Android fishers quite happy. I'm sure about it because the official Stockfish 7 compile will not come before TCEC-8 ends.

This time and for the first time we have a working arm7 compile of the Stockfish development version compiled by Jim Ablett and that's good news indeed.

The generation i'm grown within is much more patient and less hungry for daily updates. That's why  i prefer to wait for the photo finish of TCEC-8 superfinal to sail away to any new version.

For the ones who don't agree with me, HERE's the daily medecine for arm7 devices and another one HERE in arm5 devices.

Android UCI engine update: Deep Saros 2.3f JA for Android arm7

Well, not really a version update but rather a more suitable binary, knowing that the previous one was based on arm5. Now there's an arm7 binary which in normal conditions should perform slightly better than arm5. The expectation remains to be verified though.

Deep Saros is one of those countless engine variants forked from the first wave of open source engines era. The experience tells it's not a tasteful discussion to dig down deep about who, when and how developed the code. So let's just keep in mind Deep Saros is among the strongest engines around,.

Especially on Android, DS is the leading single core engine so far, even though its SMP feature is present but fails  to function. Imagine how better it could perform with 4 cores!

For those interested in some more ELOs, Deep Saros arm7 is HERE.

Android UCI engine update: Galjoen 0.31 JA

Soon after Galjoen has first appeared in Rapidroid, an update didn't wait too long to show up and put me in the unbearable need for replaying all previously played games. Thanks for the best of the timings once again.

Galjoen 0.30.2 was running fine with Fischer clock so far but the fixed time per move leads to low time usage, which is not validated for Rapidroid. I guess that the new version complies to the same specs as the old one. We will see soon how many more ELOs is added.

Download Galjoen: HERE

New Android UCI engine: Mini Rodent 1.0 JA

Mini Rodent is an intermediate step from current Rodent engine to its future second version according to its author Pawel Koziol. The idea behind Mini Rodent seems to be a complete cleanup and rewrite which keeps the essence and allows a better development.

Rodent 1.7 is currently rated 2828 ELO in CCRL 40/4. It's one of 39 anchor engines used to calibrate Rapidroid where the 32 bit Android port floats around 2640,

Since Mini Rodent as a solid reborn is rated 2725 in CCRL 40/4, let's expect 2540 from the Android port of it.

Dowload Mini Rodent: HERE

Android UCI engine update: Stockfish Dev 2015-10-28 JA

If i call this version 6.99, this would be nice joke hiding some reality in it. For sure, we are close enough to conclude TCEC-8 superfinal and if the next release of Stockfish is entitled v7.0, it will not be too surprising.

I'm sure a lot of ELO is added over Stockfish 6 but i still prefer to wait for v7 before replacing v6 in Rapidroid.

I've just checked these two compiles. Unfortunately, once again arm7 didn't load while arm5 works fine. However, it seems this issue applies to Stockfish only as arm7 versions of Arasan and Maverick are working on my Rockchip 3188 quad core.

There should be something specific in Stockfish source that leads to an incompatibility and it should be something that Arasan and Maverick don't include.

If someone manages to get the arm7 compile working with Chess for Android or Droidfish, please let me know.

Android UCI engine update: Arasan 18.1 JA

Arasan is one of the leading engines in Rapidroid, capable to trigger all your cores. I hope the new version compiled for Android by Jim Ablett will bring some more pressure on the Top-10.

Both versions are tested OK on my Rockchip RK3188 tablet.

Android UCI engine update: Maverick 1.5 Leiden

Maverick 1.0 goes to 1.5 for Android as well shortly after Windows thanks to Jim Ablett. I hope the new compile will run without issues like it was the case with the previous one.

This version had competed in WCCC-2015 in Leiden.

P.S.: Both versions are tested OK on my Rockchip RK3188 tablet.

RAPIDROID RELOADED: October-2015

Another delayed release to blame on the lack of time during week days.

The highlights are:

* ADDED Galjoen 0.30.2 as new Android engine

* ADDED Sayuri 2015.10.02 as new Android engine

* ADDED Mephisto Roma 68020 as new Windows engine

* ADDED Mephisto Roma Turbo as new Windows engine

* UPDATED Bitfoot 150707 to 150922

* UPDATED Clubfoot r2293 to 150907

* UPDATED Chenard 2014.07.11 to 2015.08.15

* UPDATED Gunborg 1.0 to 1.39

* CALIBRATED all engines according to CCRL 40/4

* EXCLUDED GreKo 13.1: Often hangs on move

* EXCLUDED Laser 0.2: Stays in RAM and hogs CPU

* EXCLUDED Mchess2: Doesn't start

* EXCLUDED Protector 1.9: Often hangs on move

ON A HOT ROOF:

Komodo 9.2 still leads. Error margins are wide enough but the superority over Stockfish 6 looks permanent. It's no surprise as major rating lists show the same on Windows. We're just witnessing that Android is no exception. I expect both Komodo and Stockfish will be updated just after TCEC-8 and maybe Rapidroid will include them in December release.

CALIBRATION HEADACHE:

I've put a lot of effort to establish a trustable correlation formula between CCRL and Rapidroid before this release without success. Grrr!

Unfortunately all below methods fail to cover the inconsistencies: 

* Use only single thread 32 bit CCRL engines as anchors, both UCI and XB or only UCI

* Use only single thread 64 bit CCRL engines as anchors, both UCI and XB or only UCI

* Use all 32 bit CCRL engines as anchors, both UCI and XB or only UCI

I'm not an expert of statictics at all but i can understand why a perfect method can't be found:

1) 40/4 is not first priority of CCRL vs 40/40 and many Android engines miss in it. However Rapidroid must be calibrated vs CCRL 40/4 and not 40/40 given the CPU speeds and time controls. 

2) Exynos 4412 is about 1.9 times slower than CCRL's Athlon X2 4600+ according to single threaded integer test of Geekbench, the only multiplatform cpu benchmark to represent chess performance because computer chess is more like integer math and not like floating point at all! At least cross-checking the results indirectly through different PC CPU's showed Exynos-Athlon equation is not far from being realistic. An error resides there though...

3) I've estimated Exynos to be 54 ELO weaker than Athlon assuming that each NPS doubling is 60 ELO. However we can't be sure whether it's 50 or 60 or 70 without deeply testing. Since i don't have time for that, the doubling estimation remains a mystery, a potential source of error.

4) There's still a distribution difference between Rapidroid and CCRL. We need to add many more samples to Rapidroid to see if the whole list will shrink more or not. I believe my ranking is slightly inflated than reality for the moment. Thus the toppers Komodo and Stockfish may be slightly overrated.

There are indeed other sources of deviation like multi thread scaling differences but let's not get into deep detail and come to the preliminary solution i've introduced: Bearing in mind the error won't be completely avoided, i've decided to distribute it in the widest possible way by using as many anchors as possible, 32 bit and 64 bit, estimating an additional gap from 32 to 64 bit. XB engines are left off given that Android implementation in Chess for Android is not at the same level as UCI.

Finally, the calibration of the ranking is now based on 39 UCI engines selected from CCRL 40/4. Rapidroid tries to place all Android engines 65 ELO lower than their 32 bit CCRL counterparts.

For 64 bit, the target is set to 110 ELO below CCRL. Simple and unproven! The usual gaps here would be 54 and 99 arithmetically but a safety margin must be preserved.

Now, i estimate the calibration error like +/- 30 ELO.

MEPHISTO SIMULATION DISASTER:

I don't own one of those Mephisto table tops from 1980s but i'd always dreamed of buying one when i was a child. Some dreams don't come true and that never happened. Hopefully after decades, we have simulation software like MESSUI which runs many older chess computers on PCs. They are really back!

More credits must be given to UCI compatible versions which can play automated games via Arena GUI. Besides, they can play vs Android engines via the network remote connection i've been using to rate Rybka and The King lately.

Therefore, two Mephisto's are welcome in Rapidroid. Indeed i had high hopes but Roma failed to reach the expected level of 1930 at original speed. With full speed of an i7 processor that didn't change too much. Only 1800 something. Great deception so far.

Should we blame the low performance on the slow network interface (wasn't it the same for Rybka anyway?) or the simulation interface MESSTINY managing things through the WB2UCI soft adapter?

Do conversions provoke a remarkable slowdown?

If always not, Roma UCI should be really that weak in bookless play, starting from 20 ply openings.

There are other oldies like Mephisto Gideon Pro or Rebel working the same way as Mephisto Roma. If i can find spare time i will test them too.
