In this paper we present a purely semantic view on non-monotonic reasoning. We follow the direction pointed in [16] and claim that any non-monotonic logic can be viewed as a resul...
Model checking is a promising approach to automatic verification, which has concentrated on specification expressed in temporal logic. Comparatively little attention has been give...
This paper investigates optimization techniques and data structures exploiting the use of so-called pseudo models. These techniques are applied to speed-up TBox and ABox reasoning...
In the clock semantics for epistemic logic, two situations are indistinguishable for an agent when it makes the same observation and the time in the situations is the same. The pa...
Recent research in nonmonotonic logic programming has focused on program equivalence relevant for program optimization and modular programming. So far, most results concern the st...
