I compile Android builds of Stockfish. Check out my page >

Arm7 builds are untested as I don't have an Arm7 device. Feedback is welcome.

Jim.
Jim could you compile sf for Android there was a fix done in 13.11, which i think is crucial for analysis and ponder on games, as I understand your latest compile is 9.11.
If you can compile the latest that would be much better.
I actually plan to try to make it run in chessbase online app, but I need first your compile. Sf7 might be delayed and we are left with sf6 running on that app for a long time.
Latest builds are up now on my site.

Jim.
excelent! as always :)

The elo of these top engines is already incomprehensible :) .
For analysis engine, it is important that the engine gives a very good estimate of the win/loss/draw probabilty. Given a position like fortress, the engine should give a reasonable score for example.

Sample run.

Code: Select all

A. System and App name
CPU name             : Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz
Operating system     : Microsoft Windows 7 Professional 
Physical cores       : 4
Logical cores        : 8
Hyper-threading      : ON
App name             : ESDP - Engine score on drawn positions v5

B. Engine settings
Threads              : 1
Hash (mb)            : 64
Time/pos (ms)        : 5000
UCI command          : ucinewgame / go movetime 5000
NumThreads names     : Threads / Cores / SMP / Max CPUs / CPUs
Endgame  Tablebase   : No

C. Test settings
Total engine count   : 2
Position filename    : DrawnHighMaterialDifference_v1.epd
Total positions      : 25
Total max points     : 2500
Estimated total time : 125000 ms (2.1 minutes)/engine

D. Summary high point is better
 1 Stockfish 6 64 POPCNT                    (Tms 108710, Pts  827, Rate 33.08%)
