Android UCI engine update: CT800 1.20

CT800 is an average level engine released by Ratmus Althoff who recently concentrated on compiling for Android and finally managed to obtain working binaries.

CT800, in fact, was born as a dedicated chess computer idea and it was designed by Rasmus Althoff.  The original CT800 featured an ARM Cortex M4 microcontroller of an Olimex H405 board that operates up to 168 Mhz, with 1 MB of flash memory, 192+4 kB of SRAM, and multiple I/O and USB connectors, with a 4x20 character text display, two leds, and a 4x4 + 1 keypad as peripherals aka user interface. Voltage source is due to four NiMH rechargeable AA batteries or external 5 V DC power supply.

The "chess computer" CT800
CT800's firmware is developed by Rasmus Althoff, released under the GPL Version 3. The chess playing software is an ARM port of George Georgopoulos' open source engine NG-play including a KPK bitbase by Marcel van Kervinck.

GET CT800 1.20 for arm7 and arm8

Previous stable version was:
GET CT800 1.12 for arm7

Development versions from 1.12 to 1.20 were:
GET CT800 1.20p11 for arm7 and arm8
GET CT800 1.20p13 for arm7 and arm8
GET CT800 1.20p14 for arm7 and arm8

  1. Hi all,

    since there was some interest here in testing the previous version, maybe that also applies to the current one. Especially with the Elo slider.

    The most relevant changes from V1.20:

    - the pre-search is cut down to 1 ply. I encountered a real game position where the 3-ply pre-search alone would take 800,000 nodes, roughly half a minute on the target hardware - way too much. A nice side-effect is that throttling via node rate works much better, which I guess Lazar will enjoy. :-)

    - the engine strength can be set in Elo. In Elo limited mode, the UCI parameters node rate, CPU speed and eval noise are overridden. The Elo setting works independently from the device, except for the maximum which is automatically calibrated to the device speed. That's quite some guesswork, and I don't expect the setting to be "exact". However, it provides an easy slider to control the strength.

    Apart from that, the engine sometimes ripped up its kingside only to notice that there is no good place to castle to, which I have fixed. Another improvement is with extremely short thinking times like in 1 second for the whole game, where the engine now is quite an over-achiever.

    1. Hello Rasmus,
      I just saw your above post...Ive now downloaded from link.yes i DO enjoy the node precision now :-) I use Ct800 regularly now as a playing/sparring partner so im
      interested in its further development.Will report back with any observations that may or may not be useful.
      Kind Regards,

    2. Hello Rasmus.Im really liking the new elo feature.i notice that for example at 2100 elo its doing 30kns but in the endgame its doing about 55kns.Is there any randomness in the move selection with the elo option or is it purely node based? ..And how does the engine determine when to increase the node speed-in the elo option ? Is it determined by move count or piece count or ? Im liking what im seeing so far!

  5. Hi Lazar,

    it's probably the move time that hits in. The configured Elo refers to 15 seconds for the current move. That can be reduced by up to 50 Elo when going down to 5 seconds per move or less because humans are not as good at blitz games. On the other hand, it can increase by up to 50 Elo for 2 minutes per move or more because humans are better at long time controls. The automatic calibration at engine startup already leaves 50 Elo headroom for the ramp-up with long time controls.

    If you set the strength to 2100 Elo and give a move time of 2 minutes or more (or analysis), the engine will have about 55 kNPS, so that would match. The speed does not depend on the game phase.

    Of course, there is still some amount of inaccuracy possible if the engine decides that it doesn't want another depth iteration, which will happen if an iteration is finished and more than 55% of the allocated move time is already over.

    Plus that there are the quick replies for obvious moves, and the depth to which the engine checks that an obvious move is actually correct will vary from 4 to 6 plies, depending on the actual node rate limit.

    The other thing is the noise, which will kick in at 1900 Elo or less - 1900 after adding/subtracting the move time related +/- 50 Elo.

    I'm happy that the scaling seems to make sense for actual human play. :-)

    regards, Rasmus

    My test of ten engines, using cfa app, I still don't know , who is the winner?
    BOOK..(no book)a single opening (Sicilian Najdorf, Byrne (English) attack.pgn) 23 moves was chosen,
    So all the engines face each other 10 times. 5time as a black and 5time as white player.
    The total played games are 450,
    Here is the proof .

  15. Hi,

    this is the V1.30 release of the CT800. Some bugfixes, the most critical a buffer overflow with "debug on" and long input lines, so updating from V1.20 is advised. There is now a slider to control the engine strength via UCI_Elo, the throttling via node rate works better, and the engine is much stronger at super-fast time controls like 1 second per game without increments. Some minor improvements to eval and search are also in place.

    This release accomodates to quirks in Arena and Droidfish with regard to threefold repetition: Arena misses the threefold when the first occurence was after a two step pawn move without e.p. possibility, and Droidfish sends the third occurence to the engine before declaring draw. In both cases, V1.20 answered with a null move that confused the GUIs, which I have removed.

    Since this is a well-rounded release, I expect +3.14 Elo at CCRL.

  21. Ok I just tested K9.42 against SF10052018 for a hundred game round robin match with time control of 10sec each side on my 6 core SD 650 phone and 256 mb of Hash each side and the result is mind bogling 82-18 win for the SF. Just to c how much powerful SF has become over K. Although K's latest official release is quite a bit stronger but yet I beleive even that would not have changed the result much. So in Android we can say that SF is clearly way stronger than K atleast in quick time control.

  69. Hi all. I have an idea to make an app for playing with leela chess from our Android phones. As everytime opening a beowser and loading the site and going to the playing page is not very convenient or time consuming. So if we have an app to play against Leela it will be quite easy to start. If some one from here post this idea on Lc0 forum then I will be greateful.

    But at least armFish got an update today - https://github.com/lantonov/asmFish/tree/executables/ARM . It's slower than Alexei's arm64 cFish, but it's still a newest Fish we can get at the moment...

    No. Just a regular break before a stormy comeback. The longer the break, the heavier the comeback :-)

    So perhaps there is hope still..although this time the break is 4+ months so far...

  94. In 2017 gurcan at least could type comments something about a long break, but in 2018 he don't even type a single word, now for sure I'm worried about his health, I hope he will be safe and sound, he is even disappeared from playing chess in FICS chess Server..

  95. From more than 17000 games of three strongest chess engines Komodo,Houdini, and Stockfish9 I compiled this book, therefore I named it kom-stock-houd.

  102. Of course Paulzzz, but this will take abit longer because I have only a chance of two hours to work with PC, and you know here is the summer hottest weather, I'm already working on engines pgn to bring them to binaries, and how much depth of moves would it be better for update of kom-stock-houd?

    1. I think 8-10 moves from white and black should be perfect, Karim. Thanks for your hard work friend, appreciate this :)
