We study probabilistic complexity classes and questions of derandomisation from a logical point of view. For each logic L we introduce a new logic BPL, bounded error probabilistic ...
A method is described for proving “always possibly” properties of specifications in formalisms with linear-time trace semantics. It is shown to be relatively complete for TLA...
Description Logics form a family of formalisms closely related to semantic networks but with the distinguishing characteristic that the semantics of the concept description langua...
We consider how to forget a set of atoms in a logic program. Intuitively, when a set of atoms is forgotten from a logic program, all atoms in the set should be eliminated from thi...
This paper surveys previous work on combining planning techniques with expressive representations of knowledge in description logics to reason about tasks, plans, and goals. Descr...
