I've managed (at long last!) to compile a windows
executable of the Apilchess/Hydra uci chess engine source
code by U. Lorenz and Chrilly Donninger.
http://wwwcs.uni-paderborn.de/fachberei ... chess.html
Primarily designed for custom multiprocessor/parallel computing
hardware, it also works on single processor systems, but is
obviously significantly weaker as a result.
Apilchess's code is very sophisticated, but it's strength (on
single processor systems) is pretty weak, evaluation is
under-developed - about equal or slightly better than TSCP.
It plays a lot better using an opening book, without one, it
always seems to start with Anderssen opening a2-a4!
When I first compiled the code, the hashtable memory allocation
was 350mb! I've adjusted this to 65mb. A different hashtable size
can be compiled on request. I've also made small adjustments to
time allocation and static piece values.
Also there is a folder called 'error' in the ApilChess folder - this
has to be there! and when you first start ApilChess it opens a port
on your computer (not sure why - something to do with the i/o pipes in
MPich?) that will alert your firewall. If you're worried about this
just block it.
Since this early code was released in 2003, the Hydra project has
progressed to the point where it is probably the strongest chess
computer ever - read here > http://www.hydrachess.com/
Intel optimized build.
Windows-adapted source code available on request.
Thanks to Dann Corbit for compiling advice posted on the
old Winboard forum.
Available from my homepage.
