Using Nested Logic Programs for Answer Set Programming
We present a general method to improve computation of answer sets by analyzing structural properties of normal logic programs. Therefore we use labeled directed graphs associated t...

Beyond Bidimensionality: Parameterized Subexponential Algorithms on Directed Graphs
In 2000 Alber et al. [SWAT 2000 ] obtained the first parameterized subexponential algorithm on undirected planar graphs by showing that k-DOMINATING SET is solvable in time 2O( ...

A polynomial time equivalence between DNA sequencing and the exact perfect matching problem
We investigate the computational complexity of a combinatorial problem that arises in DNA sequencing by hybridization: The input consists of an integer together with a set S of wo...
