RAPIDROID RELOADED: February-2016 with Stockfish 7, finally

Stockfish 7 finally comes in and replaces its predecessor 121215 on top of Rapidroid. Nothing unexpected here since Komodo 9.3 had lost the leadership in January list, after a shocking regression of some forty ELOs which i assumed to be specific to Android, in contrast to Windows, where 9.3 and 9.2 perform almost the same. 
This build of Stockfish just added some more gap over Komodo. I wish i could revert back to Komodo 9.2 but it's technically impossible for any device on which 9.3 is installed once.

The unnecessary complementary info of this release is that i've dropped Robocide and Virutor from the list of CCRL anchors as their Android builds play better than Windows counterparts. I won't be looking for an explanation of this. The other 40 engines remaining are still enough to keep a good balance between two operating systems. Cutting off the extreme deviations should be healty.

The impact of dropping two engines is about +12 ELO for the whole list. The average gap of Android engines vs their targets calculated from CCRL is now around 35 ELO which is acceptable for a list with 300 games per engine. 

I hope that March-2016 release will be fun with Fritz, Gull and Ivanhoe. They may disturb the peace in the top segment as they are expected to reach 3060, 3050 and 2950 ELO respectively.

The highlights of this release:
* UPDATED Crafty 24.1 to 25.0 arm7
* UPDATED ExChess 7.71 to 7.88 arm7
* UPDATED Phalanx XXIV arm5 to arm7
* UPDATED RedQueen 1.1.97 to 1.1.98 arm7
* UPDATED Stockfish 121215 to 7

The list 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 Fritz 14, Gull 3 and Ivanhoe 9.47c Beta

  1. Gurcan, thank you for your work!

    It is unfortunate that critter is not developed.
    I'm glad to see Phalanx. It's engine with very interesting style of play. Since many years, from time to time I playing against in long game and analyzing sharp positions.

    Unfortunately, the Phalanx does not support the UCI protocol on android. Analyses would be easier in a good application.
    Maybe Jim Ablett could extend this engine in the UCI support ?

    Regards, Dariusz

  3. I am currently running a 10 game tournament with Gull 3 and Ivanhoe 9.47c beta versus about a dozen of the top free engines (Robolitto .085e41 to Stockfish 7) So far, Gull has come in around 3150 and is an equal to Critter 1.6. Still working on Ivanhoe. Won't be testing Fritz as it is commercial.

  4. Archie, thanks for the feedback. Rapidroid March-2016 will include Gull, Fritz and Ivanhoe. On Exynos 4412, Fritz and Gull are both close to 3100, still a little bit lower than Critter. Ivanhoe is very similar to Robbolito, close to 3000. They all played 300+ games already. I think Gull could perform even better. My sixth sense tells me there's a little bug in JA builds making the SMP code less efficient than expected. It doesn't use all available cores all the time, simply unstable...

  5. @Vadlm: Senior Chess shoukd be around 1900-2100. I will test it with 20 manual games whenever possible.

  7. Here is the data on Gull 3 and Ivanhoe 9.47c beta. Versus 11 other top engines, 10 games per match, 110 games per engine; Gull scored 60% and has a rough ELO of 3159. Ivanhoe scored 40% with a rough ELO of 3019. (Sidenote: Senpai 1.0 got seriously worked over by the rest of the engines in this list. Not a worthy performance from a supposedly 3000+ engine.)
