In this dissertation we discuss problems of search, inference and opponent
modelling in imperfect information games in the context of creating a
computer player for the popular german card game skat. In so doing, we
demonstrate three major contributions to the field of artificial
intelligence research in games. First, we present our skat player
Kermit which, using a synthesis of different techniques, decisively
defeats previously existing computer players and displays playing
strength comparable to human experts. Second, we propose a framework
for evaluating game-playing algorithms with known theoretical flaws
and explaining the success of such methods in different classes of
games. Finally, we enhance Kermit with a simple but effective opponent
modelling component that allows it to adapt and improve its
performance against players of differing playing strength in real
time. -
