ABSTRACT
In this thesis we present preliminary results in the development of LIBRA
(LInköping Behavior Representation for Agents). LIBRA is a rule-based system
for specifying the behavior of automated agents that combine reactivity to an
uncertain and rapidly changing environment and coordination. A central
requirement is that the behavior specification should be made by users who are
not computer and AI specialists. Two application domains are considered:
air-combat simulation and a simulated soccer domain from the perspective of
the RoboCup competition. The behavior of an agent is specified in terms of
prioritized production rules organized in a decision tree. Coordinated
behaviors are encoded in the decision trees of the individual agents. The
agents initiate tactics depending on the situation and recognize the tactics
that the other team members have initiated in order to take their part
in it. What links individual behavior descriptions together are explicit
communication and a common means to describe the situation the agents find
themselves in.
