Stockfish NPS (Dev) Android Builds

Optimized for Android: SFMXnps Pre-release

SFMXnps is stronger than Stockfish17dev on Android. To proof this and, in particular, to become more familiar with testing on an Android device, a large number of c-chess-cli tournaments were performed and are shown below.

All tournaments were played on a Xiaomi Poco M3 (Android 12, Snapdragon 662, 4 GB RAM) using Termux and the CETSA script, which utilizes c-chess-cli. Concurrency was set to 4 and TCs from 5+0.05s to 120+1.2s with 1 thread per engine were tested. Also one tournament with 2 threads and concurrency 2 was carried out to test the SMP performance. More details are given in the configuration files which can be, together with the played games, downloaded below.
The absolute value of the rating was set to 3100 ELO for each tournament and the rating offsets and all other values were calculated by the script with Bayeselo. Opening suite was UHO_2022_8mvs_+110_+119.epd. It should be noted that such kind of openings enlarge ELO differences but have the advantage of reduced draw rates.
