We give a fully polynomial randomized approximation scheme to compute a lower bound for the matching polynomial of any weighted graph at a positive argument. For the matching poly...
We provide bounds to the rate distortion tradeoff of the binary Markov source with the Hamming distance as the distortion measure. The tradeoff has been completely characterized b...
Formal verification is an important issue in circuit and system design. In this context, Bounded Model Checking (BMC) is one of the most successful techniques. But even if all sp...
Kadin [6] showed that if the Polynomial Hierarchy (PH) has infinitely many levels, then for all k, PSAT[k] ⊂ PSAT[k+1]. This paper extends Kadin’s technique and shows that a p...
We resolve an open question raised by Feige & Scheideler by showing that the best known approximation algorithm for flow shops is essentially tight with respect to the used low...
