The complexity of irredundant sets parameterized by size
An irredundant set of vertices V V in a graph G = (V; E) has the property that for every vertex u V ; N[V - {u}] is a proper subset of N[V ]. We investigate the parameterized co...

On the Complexity of Verifying Consistency of XML Specifications
XML specifications often consist of a type definition (typically, a DTD) and a set of integrity constraints. It has been shown previously that such specifications can be inconsiste...

Evaluation of Search Heuristics for Embedded System Scheduling Problems
Abstract. In this paper we consider the problem of optimal task allocation and scheduling in embedded real-time systems. This problem is far from trivial due to the wide range of c...
