Restarts and Nogood Recording in Qualitative Constraint-based Reasoning
Abstract. This paper introduces restart and nogood recording techniques in the domain of qualitative spatial and temporal reasoning. Nogoods and restarts can be applied orthogonall...

Disjunctive Temporal Reasoning in Partially Ordered Models of Time
Certain problems in connection with, for example, cooperating agents and distributed systems require reasoning about time which is measured on incomparable or unsynchronized time ...

Qualitative Temporal and Spatial Reasoning Revisited
Abstract. Establishing local consistency is one of the main algorithmic techniques in temporal and spatial reasoning. In this area, one of the central questions for the various pro...

An Algebraic Formulation of Temporal Knowledge for Reasoning about Recurring Events
We formulate an algebra of binary temporal relations between events the number of occurrences of which is unknown, but which are known to recur in time. Ontologically, we view the...

Fixed-Parameter Hierarchies inside PSPACE
Treewidth measures the ”tree-likeness” of structures. Many NP-complete problems, e.g., propositional satisfiability, are tractable on bounded-treewidth structures. In this wo...
