*** PMReversi, a Reversi/Othello game for OS/2 PM. ***
******************************************************


HISTORY:

1.) V.0.9 (26th May 1997)

Interested in genetic algorithms and artificial intelligence in general,
I started in 1992 to write a game of Reversi in MS Basic PDS under DOS.
As speed became more and more important, I decided to switch to OS/2 and
rewrite the whole thing in C. Over the past years it has become a kind
of funny competition between me an my friend Dirk Schtz at the FH Gummersbach,
who released his Reversi for the world of Atari (Black & White) with a fine
graphical interface already. After tons of code lines and even more ideas
implemented and discarded, I thought it was time to upgrade my text mode
interface to OS/2 PM. Still a bit rough around the edges, my promise to enhance
the graphic (and the playing strenght) is given here.

2.) V.0.91 (1st June 1997)

Powered by some ideas of a Reversi game I found at
http://www.lglwww.epfl.ch/~wolf/java/html/othello.html,
I was able to improve the strength of my program considerably.
Thanks to the author! Further more "Think on opponents time" is now
implemented. When you play against the machine and this option is enabled
in the <settings-dialog>, the program will use the time you are thinking
about your own move to look for the reply. But there is a little drawback.
As the number of threads increases, depending on how many moves you can make,
it may take 1-2 seconds to see an action of the program by updating the board
after you made a move. So be patient.

2.) V.0.92 (15th June 1997)

When playing at higher leves (>=7) and the game is getting near the end, it
sometimes occured that the program makes one or two completely wrong moves.
This bug is removed. After many games of testing, the linear combination of
the evaluation function is shifted to put more weight on the potential mobility
rather than on the edge table. This improved the strength of the program
even more.
