On Programs with Linearly Ordered Multiple Preferences
The extended answer set semantics for logic programs allows for the defeat of rules to resolve contradictions. We propose a refinement of these semantics based on a preference rel...

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...
