More Engines

-
I made various improvements in the WinBoard/XBoard implemention in Chess for Android and are now able to successfully import and play with the following XBoard engines (I also tested the corrected UCI sungorus engine).

Crafty 23.4                  Robert Hyatt
scorpio 2.7                  Daniel Shawul
sloppy 0.22                  Ilari Pihlajisto
tscp1.81                     Tom Kerrigan
sungoros-14-ja               Pablo Vazquez

Below, I posted the cross-table of a quick test tournament from both sides of just the first position of the Nunn opening suite.
                     1  2  3  4  5  6  
1 scorpio            ** 01 11 11 11 11   9.0/10
2 crafty             10 ** ½1 1½ 11 11   8.0/10
3 sloppy             00 ½0 ** ½1 11 11   6.0/10
4 Sungorus 1.4 JA    00 0½ ½0 ** 11 11   5.0/10
5 tscp181            00 00 00 00 ** 11   2.0/10

Checkers Move Generation

-
I was able to make a small improvement in the checkers move generator (written in Java for the Android SDK). The following table shows run times of several perft depths before and after optimization when run on the emulator (which should mimic actual run times on the phone quite well). DEPTH #LEAF NODES ORIGINAL OPTIMIZED TIME TIME ==================================== 7 179740 2.9s 1.9s 8 845931 14.2s 9.7s 9 3963680 66.3s 45.6s 10 18391564 294.6s 208.7s P.S. Runtimes for a C++ checkers move generator on a 2.2 GHz Core 2 Duo are given at my checkers page .

Connecting Chess for Android to a Remote Server

I have received several questions on how to connect Chess for Android running on an Android device (e.g. a phone) as client to a remote chess server (e.g. a powerful desktop), so I decided to write a small document with detailed instructions. What you will need: The server software from Bernhard Wallner's chess utilities , suited for your server's operating system (if, say, your desktop runs Windows, you will need to download the Windows version). You do not need to download the client software in this case. The network enabled version of Chess for Android . On the server, start the engine server software, and construct a new row for every engine you want to run remotely. Assign a name, port number, and select the full path to each engine binary (an executable that runs on the server). You can also supply command line options for starting the engine. Check the active checkboxes and click start when done. This yields something similar to the screenshots below. Here, I have s...

Connecting with the DGT Board

After all the fun I had connecting Chess for Android with the Millennium  over Bluetooth, I was curious if I could provide similar support for the DGT electronic chess boards. Some of these have Bluetooth capabilities, most use USB connections, and some older models, like the one I have, still use the RS-232 connector. To my pleasant surprise, by combining the original serial cable of DGT with a USB-to-serial cable and a female-USB-to-USB-C cable, I was able to get an actually working connection between my DGT board and my tablet or phone. Next was implementing support in Chess for Android. Luckily, DGT kindly shared the protocol documentation with me, and after a fun weekend of hacking, Chess for Android now proudly supports DGT electronic chess boards as well.
