The program is now working on a ten billion game run which should take a total of about 23 days of single core CPU time. However, that may be too long of a run since the random number generator in use has a period of about 2^34 (ca. 34 billion). Each random game requires on average about 334 random ...

Re: Code snippets
We assumed that gmvec function is the set of ALL the legal moves computed from your chess engine. Then, instead of your engine calculating the relative strength of the legal moves, the RandomPick function selects one move from the set & assigns the vector to the variable "move". And h...

If a Debian version of Linux (like Raspbian) is running on a Raspberry Pi connected to the Internet, only a single line entered at a text console instance is needed to install Stockfish: sudo apt-get install stockfish The same is true of most other chess software residing in the Debian package world.

Instead of buying a Revelation II, I'll make my own Revolution I. I'll use my DGT board, its DGT pieces, a cheap Android tablet, some connection circuitry, and some of my own chess software with voice I/O. All the custom stuff will go in a separate wood box which will connect to the board with a co...

Grippers
The robot arm can use one of several different grippers. Those seen in the above photograph aren't suitable for moving a chessman, so a different and possibly custom gripper is needed. The gripper in the furthest arm uses a suction cup instead of a pincer. It could work with a set of chessmen if eac...

Chess on the Raspberry Pi
This is a topic thread for Raspberry PI chess work. https://dl.dropboxusercontent.com/u/31633927/Pics/raspberrypi.jpg I have ported the development version of Symbolic to my Raspberry Pi board. I've overclocked the board from 700 MHZ to 800 MHz and many long tests have shown this speed-up to fully r...

The network connectivity problem has been solved by a cable swap (which probably didn't do anything) and by swapping out the Onn mouse for a mouse by Acer. Now my RaspPi can get the correct date/time automatically when it boots and I can get updates installed (rather slowly). I did not have to add a...
