An SWCR engine test shows that Ivanhoe 999946b has about a 20-30 ELO improvement over B47cB! That makes it just a few ELO short of Deep Rybka as the 2nd strongest engine IN THE WORLD!!!

Compliments of the season!! IvanHoe 999946h package has been re-uploaded with addition of Android support. It should work on Froyo (2.2), but tested only on Gingerbread (2.3.x). RobboBase usage is untested.

7b920df9ecc1a759bae5c01ea4bab9e6 IvanHoe999946h.7z

Code:

db5cc6b67fdbe18eedf5b75173a04153  ./Android/RobboBaseLib.so
cb097cfaadd7cbf9e3a66986e2febc43  ./Android/IvanHoe999946h

Changes were made to accommodation the portable device build which includes, but not limited to trimmed UCI options:

Code:

option name Hash type spin min 1 max 1024 default 8
option name Threads type spin min 1 max 4 default 4
option name Ponder type check default false
option name RobboBaseDynamicLibraryFile type string default NULL
option name RobboTripleBaseDirectory type string default NULL
option name RobboTotalBaseDirectory type string default NULL
option name LoadOnWeakProbe type combo var AllWays var UnlessPondered var Refrain default AllWays
option name UnloadDeregisterInform type combo var Inert var DeRegisterTotal var UnLoadTriple default Inert
option name MultiPV type spin min 1 max 250 default 1
option name SendCurrmove type check default true
option name UCI_Chess960 type check default false

For some multi-core devices (e.g. my HTC Sensation), number of processors auto-detection is always set to one. /proc/cpuinfo also returns 1, but UCI Threads option allows increasing the value.
