Abstract

Planning domain analysis provides information which is useful to the domain designer, and which can also be exploited by a planner to reduce search. The TIM domain analysis tool infers types and invariants from an input domain de¯nition and initial state. In this paper we describe extensions to the TIM system to allow efficient processing of domains written in a more expressive language with features of ADL: types, conditional efects, universally quantifed effects and negative preconditions.
