Android UCI engine update: Chiron 4

The new Chiron 4 is about 70 points stronger than Chiron 3, according to the author Ubaldo Andrea Farina. Although it's an update to the engine, the Android app is a different one and will keep Chiron 3 alive on the same device. Interested users can even make two versions play each other the same way as it's possible between Komodo versions.

Chiron 4 costs 2.5 EUR only and the licence checking works exactly like Komodo via Google Play.

WHAT'S NEW (10-Jan-17):

– improved automatic tuning of the evaluation
– improved evaluation of passed pawns, mobility, opposite bishops endings
– improved forward pruning in the search
– improved LazySMP for parallel search
– support for Windows Processor Groups (more than 64 threads can now be used)
– NUMA optimization (new UCI and Winboard options “NUMA”)
– minor speed optimizations
– fixed a pondering bug
– fixed two time management bugs under the Winboard protocol

Chiron 4 is available for Windows and Android.
Buyers of the Windows version will also receive a code to get the Android one for free.

Chiron 2/3 Customers can buy Chiron 4 with a discount through the link they have reiceved. Whoever has bought Chiron 3 in the last month will receive Chiron 4 for free.

Download Chiron for Android on GOOGLE PLAY.

I made first test between Chiron 3 and 4, Lenovo TAB 1GB RAM, 4 cores, 64mb hash, 100 games, book-Rybka.bin, time 2min+1sec.
Score - Chiron 3 (39)-Chiron 4 (61), it's a good start!!

Yes indeed. I still need time to publish a Rapidroid update. However, first rounds leave no doubt about Chiron 4 in 3rd place behind Stockfish and Komodo. It performed better than the oldie Critter arm5. Something that took too long to happen...
