Development on CPP1 has stopped now that a new program called POS is under development.
CPP1 - An experimental OO chess program
What is it?
A chess-program :o)
It's an experimental one: not because of the bugs, but because of the algorithms used. Not just one based on the
shannon-algorithm, but several. And, the most important one; it is not brute force.
The program should now fully support xboard/winboard. Start it with commandline "-iomode xboard".
An announcement- and discussion mailinglist has been started on which I will announce new versions of my chess-programs and things related to chess.
Send an e-mail to firstname.lastname@example.org with in the subject 'subscribe chess' to subscribe.
It's a console-application so screenshots are not that usefull, but what the heck: screenshot.
1999-12-01 001 fixed bug in move-selection (would always use the same algorithm, which is not always appropriate) 1999-12-01 002 fixed bug in code that analyzed who is attacking who 1999-12-07 001 user can now select the color to play with 1999-12-07 002 rewrote some code (C pointer to by reference/by value) 1999-12-07 003 implemented new algorithm, this one is to make the program more protective 1999-12-15 001 beautified code 1999-12-15 002 started working on I/O-abstraction (for ICS/Xboard-interfacing) 1999-12-15 003 fixed memory-leak 1999-12-15 004 some cosmetic I/O changes 1999-12-15 005 implemented new algorithm that generates move that can seem to be chosen on emotional grounds 1999-12-27 001 this release only works with WinBoard 1999-12-27 002 some changes to the routines that select a move from the rated moves 2000-01-01 001 redesigned and started rewriting move-selection routines 2000-01-01 002 fixed bug in pawnpromotionfinder. in the rare case were multiple promotions are about to occure, funny things might have happened when one was under attack 2000-01-01 003 implemented commandline parameters: -mfile , -iomode xboard|console 2002-03-24 001 re-evaluated evaluation routines 2002-03-24 002 added new algorithm 2002-04-03 001 a new evaluation subroutine was added 2002-04-03 002 implemented en-passant 2002-04-08 002 implemented trans. table 2002-04-20 001 improved xboard/winboard support 2003-09-14 001 relased MacOS X binary 2006-08-05 001 added '--mem' switch
