  abstract = {Many plan-based autonomous robot controllers generate chains of
abstract actions in order to achieve complex, dynamically changing,
and possibly interacting goals. The execution of these action chains
often results in robot behavior that shows abrupt transitions between
subsequent actions, causing suboptimal performance. The resulting motion
patterns are so characteristic for robots that people imitating robotic behavior will do so by making abrupt movements between
actions. In this paper we propose a novel computation model for the execution
of abstract action chains. In this computation model a robot first
learns situation-specific performance models of abstract actions. It
then uses these models to automatically specialize the abstract
actions for their execution in a given action chain. This
specialization results in refined chains that are optimized for
performance. As a side effect this behavior optimization also appears
to produce action chains with seamless transitions between actions.}
