Conditional Inequalities and the Shortest Common Superstring Problem
We investigate the shortest common superstring problem (SCSSP). As SCSSP is APX-complete it cannot be approximated within an arbitrarily small performance ratio. One heuristic tha...

On the Production of Anorexic Plan Diagrams
A "plan diagram" is a pictorial enumeration of the execution plan choices of a database query optimizer over the relational selectivity space. We have shown recently tha...

Stability analysis for sampled-data systems with a time-varying period
— This paper proposes a novel stability analysis of linear systems with sampled-data inputs. Inspired by the inputdelay approach and the stability of impulsive systems, this meth...

Optimal Metric Planning with State Sets in Automata Representation
This paper proposes an optimal approach to infinite-state action planning exploiting automata theory. State sets and actions are characterized by Presburger formulas and represent...

Robust Robotic Path Planning Using Level Sets
In robotic navigation, path planning is aimed at getting the optimum collision-free path between a starting and target locations. The optimality criterion depends on the surround...
