Android UCI engine update: Stockfish Dev 2015-10-08 JA

In parallel to TCEC-8 progressing stage by stage until an unexpected result, every stage becomes a pool on speculations whether Stockfish can take back the crown from Komodo.

No doubt, the head-to-head race makes the development compiles attracting. People are insterested to test new versions each and every day before the official update comes. Unstoppable incredible hunger...

Some days ago, we have seen 2015-09-07 version of Stockfish compiled by Peter Österlund. It's in my repository available for the most hungry ones :-)

After a little while, it's now too old as Jim Ablett compiled another dev't version dated 2015-10-08. This one is interesting because we have an arm7 compile from JA for the first time.

Remembering that a previous close tourney between Stockfish compiles revealed that JA compiles perform very well, the arm7 compile from JA might deserve attention.

If i have enough spare time remaining from endless working hours, i want to play another close tourney between Stockfish 6 official, dev 2015-09-07 and dev 2015-10-08.

Or should i push back my appetite and remain patient until Stockfish 7 official release comes?

New Android UCI engine: Laser 0.2 beta JA

Put your laser lights on! This one makes yet another Android engine. The fleet keep growing and my smile gets more visible.

Welcome then Laser 0.2, written by Jeffery An, compiled by Jim Ablett.

To use it with Chess for Android, don't forget to follow the uci2xb procedure and don't rename the ini file. You may use ini file settings however.

Download it: HERE

Android XB engine update: Chenard 2015.08.15 JA

Chenard, currently one of a few stable and trustable XB engines under 2000 ELO, just got an update over the previous version of July 2014.

I just can't wait to check and see how forward the gameplay has stepped.

Please note that the filename is based on the source code update date in the download link below, not the date of the compile as used by Jim Ablett. However the binary is the same: Commit number 5102f59f52

Android UCI engine update: Bitfoot 15.09.22 JA

Bitfoot is the bitboard version of Clubfoot engine. Almost 200 ELO gap proves that the bitboards lead to stronger play.

Below binary compiled by Jim Ablett is based on the source code of September 22th. I've prefered to rename it according to the commit date instead of Jim's Oct 10th. This is always the same binary and the unique code of the source is d9aeb437d6 in github.

Enough said, HERE is the Android binary to download and try.

Android UCI engine update: Clubfoot 15.09.07 JA

Clubfoot is approximately 200 ELO wekaer than its big bro Bitfoot. However, its development is ongoing. Now, we have now a recent compile for Android based on the source code dated Sep,7th.

Once again, i've renamed the engine binary using the commit date instead of the compile date used by Jim Ablett. The exact commit number of the source is 048995de70.

Please note that Clubfoot only played fixed time per move games in Rapidroid. In case the new version plays Fischer clock games without problem it will become a passepartout engine and will use both time controls. That means the oppoonent portfolio will be enlarged and the accuracy will increase.

Android UCI engine update: Sayuri 2015-10-01 JA

Another engine i could not succeed to run flawlessly in my Rapidroid experiment used to be Sayuri. It's a medium strength engine which is frequemtly updated by its author Hironori Ishibashi.

What makes Sayuri special to me is its ability to use multi threads. I'll be glad to recall it for duty and get it rated soon whenever the compatibility tests are okay.

Jim Ablett named binary according to his compiling date but i've choosen to rename it using the commit date of the source. It doesn't matter anyway unless nobody else compiles Sayuri. Let's note that the commit number is exactly 2b47cdd70a.

Android UCI/XB engine update: GreKo 13.1 JA

Although i'm stuck on v12.5 in Rapidroid, GreKo is updated to 13.1 for Andoid by Jim Ablett. Previous 12.6 and 12.8 compiles were hanging randomly during my engine tournaments. I wish 13.1 doesn't repeat this, so that i can rate the most recent one.

Under Android, use GreKo only in Winboard protocol mode. Therefore only with Chess for Android, since it's the sole GUI compatible with it.

Usage of the ini file and the book is not mandatory. However, the ini file works and can allow selecting higher hash sizes at least.
