It was unfortunate to skip the release of July but August here takes the revenge with a lot of games and programs added. Hooray!
From June to August, Rapidroid increases from 115 to 117 engines only because of 4 engine updates but from 6346 to 8966 games. More games = More precision after all.
The highlights of this release are:
* DELETED BeeKay due to similarity with Komodo 9 (Doch remains as per larger elo gap)
* DELETED DanasahZ due to similarity with Danasah 5.07 as per the author's advice
* DELETED Bismark due to frequent hangs and bad terminations
* DELETED Joanna due to systematic need for checking and adjudicating the terminations
* UPDATED Komodo 9 to Komodo 9.1 (no ELO change expected in Android)
* UPDATED AND REPLACED Arasan 17.5 by Arasan 18.0
* UPDATED AND REPLACED Cheng4 0.38 by Cheng 4.39
* UPDATED AND REPLACED Hakkapeliitta 120115 by Hakkapeliitta 3.0
* UPDATED AND REPLACED Chess Pro 2013.09 for iOS by 2016.02 64 bit version
* ADDED ExChess 7.71b
* ADDED Bitfoot 1.0 of 07-07-15
* ADDED Superpawn b108
* ADDED Chess Titans as first Windows engine
* ADDED Shredder 1.7.0 for iOS
* ADDED Chess Wise 3.1.7 for iOS
* CANCELED UPDATE of GreKo from 12.5 to 12.8 due to frequent hangs on move
* TESTED AND DISQUALIFIED Galjoen for bad time management
I've choosen Chess Titans as first Windows engine to test just because of endless speculations about its strength in various websites. I was quite surprised to read comments stating it plays at 1700 ELO. Less than ten games reveled the truth. That Windows bundle is really weak. It used approx 11 sec on my i7-M620 at the strongest level which is fair enough vs its rivals. It had 1197 ELO only.
It's nice to include strong IOS programs in Rapidroid, mainly Hiarcs and Shredder. They cope very well with top Android engines, thanks to the A7 processor which delivers about 20% to 50% more Knps compared to Exynos 4412. I'll keep pushing them more manual games to narrow their error margins.
Regarding Stockfish for iOS, i can't introduce it as per the "anti-distortion rule" i try to follow. However i must admit it would probably top the list given that the initial position benchmark favors iPhone with ~1000 kNps vs 750 kNps of Exynos.
I schedule the next release for late September with below additions:
* INTRODUCTION of Fridolin 2.0.0 (2360 ELO expected)
* INTRODUCTION of Novag Secondo as first dedicated chess computer (950 ELO expected)
* INTRODUCTION of Excalibur Chess Explorer LCD (1300 ELO expected)
* More manual games...
