Cosmological lower bound on the circuit complexity of a small problem in logic
An exponential lower bound on the circuit complexity of deciding the weak monadic second-order theory of one successor (WS1S) is proved. Circuits are built from binary operations, ...

Complexity of Axiom Pinpointing in the DL-Lite Family of Description Logics
We investigate the complexity of axiom pinpointing for different members of the DL-Lite family of Description Logics. More precisely, we consider the problem of enumerating all mi...

Characterizing Data Complexity for Conjunctive Query Answering in Expressive Description Logics
Description Logics (DLs) are the formal foundations of the standard web ontology languages OWL-DL and OWL-Lite. In the Semantic Web and other domains, ontologies are increasingly ...

The Complexity of Generalized Satisfiability for Linear Temporal Logic
In a seminal paper from 1985, Sistla and Clarke showed that satisfiability for Linear Temporal Logic (LTL) is either NP-complete or PSPACE-complete, depending on the set of tempora...

Using logic to handle conflicts between system, component, and infrastructure goals in complex robotic architectures
Abstract-- Complex robots with many interacting components in their control architectures are subject to component failures from which neither the control architecture nor the impl...
