Reflections on Multivariate Algorithmics and Problem Parameterization
Research on parameterized algorithmics for NP-hard problems has steadily grown over the last years. We survey and discuss how parameterized complexity analysis naturally develops i...

Locality and Hard SAT-Instances
In this note we construct a family of SAT-instance based on Eulerian graphs which are aimed at being hard for resolution based SAT-solvers. We discuss some experiments made with i...

On Parameterized Approximability
Abstract. Combining classical approximability questions with parameterized complexity, we introduce a theory of parameterized approximability. The main intention of this theory is ...

Intractability of Clique-Width Parameterizations
We show that Edge Dominating Set, Hamiltonian Cycle, and Graph Coloring are W[1]-hard parameterized by clique-width. It was an open problem, explicitly mentioned in several papers,...
