Critter 1.4 for Android

Image
Richard Vida released Critter 1.4 , including a version for Android. This ARM binary imports well into Chess for Android . A quick 1-second-per-move tournament from both sides of all opening lines in the Nunn test suite on a Nexus S ended in favor of the previous version though.

DoubleCheck2.3 for Android

Image
Lucas Braesch released DoubleCheck 2.3  and I put an ARM binary on UCI and XBoard engines for Android  (you can find another binary for ARM on Jim Ablett's website ). Below, I show the results of a quick one-second-per-move tournament played from both sides of all lines in the Noomen test suite 2012  between some recent versions (32MB hash size, Nexus S).                   1         2          3                             1 DoubleCheck 2.3     *     36.5-23.5  39.5-20.5  76.0/120 2 DoubleCheck 2.0 23.5-36.5     *      35.5-24.5  59.0/120 3 DoubleCheck 1.3 20.5-39.5 24.5-35.5      *      45.0/120

TjChess for Android

Image
Another engine for ARM-based Android devices! Tony Hecker kindly made ARM binaries of  Tjchess  available as either an UCI engine or a XBoard engine. Both import well in Chess for Android . Some screenshots below. With so many new engines, is it time for yet another Android chess engine tournament ?

Umko for Android

Image
The list of chess engines compiled for ARM-based Android devices keeps growing. Someone pointed me to Borko Boskovic's Umko engine. I tested this UCI engine in Chess for Android , and it works well. Some screenshots below.

Android Engines Tournament: Group A

Image
Group A has finished a complete thirty seconds-per-move tournament in Chess for Android , played from both sides of all positions in the Nunn opening suite under the conditions described earlier. Congratulations to Richard Vida for Critter 's victory in this tournament! All games can be downloaded from the tournament page . This completes the Android tournament with longer time controls (although since many more engines are available now, perhaps another one is already necessary!).                        1         2        3         4         5                     1 Critter 1.2 32-bit       *     11.5-8.5  9.5-10.5  15.0-5.0  11.5-8.5  47.5/80 2 Stockfish 2.1.1 JA    8.5-11.5     *    13.0-7.0    9.5-10.5 11.0-9.0  42.0/80 3 Komodo32 2.03 AB     10.5-9.5   7.0-13.0    *      13.0-7.0  11.5-8.5  42.0/80 4 RobboLito 0.085g3l    5.0-15.0 10.5-9.5  7.0-13.0      *     12.0-8.0  34.5/80 5 IvanHoe-Beta v999947c 8.5-11.5  9.0-11.0 8.5-11.5   8.0-12.0     *     34.0/80
