Just installed it to check it out. The default setting is medium so I played at
a game at this setting, and won rather easily. Unfortunately it appears the
game is not saved and so cannot be shared. The medium setting is what I would
consider fairly weak. The available settings are Easy, Medium, and Hard. I
haven't tried hard yet.
Here's something from the page:
"The story of the Accoona chess AI
The Accoona AI Chess Game is an experiment in Artificial Intelligence.
Normally a chess program is programmed to do a "search", i.e. play through
thousands of possible continuations in memory, compare the outcome of each line
and then pick the one that appears most promising.
The critical part is evaluating the positions at the end of each line. This is
done by telling the program as much as possible about the value of the different
chess pieces, the importance of mobility, center control, king safety, pawn
structure, and about 30-50 other criteria. This knowledge comes from centuries
of chess research.
The Accoona AI Chess Game takes a different approach. It has received only very
rudimentary chess knowledge from its programmers, and thus takes a very naive
view of the game. But it learns. It plays like a beginner who is slowly finding
out which strategies are good and which cause him to lose the game.
Naturally it is not the tiny Java program that you are playing against that does
all of this. It merely plays and then reports back to the main chess
intelligence, located in the Accoona Chess AI lab, on what has transpired. This
AI is driven by the analytical tools of Fritz, the world's premium chess playing
software, and the German chess database company ChessBase.
Based on the analysis of tens of thousands of games received by the central
server the Accoona AI modifies the evaluators of the Java applet, which becomes
progressively stronger the more games it plays. It is modifying its opinions and
discovering new ideas and strategies all the time. You can watch it "learn from
experience" and grow more intelligent month after month.
We would like to mention one other aspect of this AI experiment. The Accoona AI
Chess Game also analyses the way humans, especially rank amateurs, lose their
games against the program. And it tries to emulate this weak human playing style
for its "Easy" level. After all the vast majority of visitors to this site are
casual players who don't have a snowflake's chance in hell to beat this machine.
But just wait .. it will become creatively weak in Easy mode.
News and reports on progress of the Accoona AI Chess Engine will be added here.
