Spiroergometrie in der Pneumologieng several axes. First, we weaken the center separation bound by a factor of ., and secondly we weaken the proximity condition by a factor of . (in other words, the revised separation condition is independent of .). Using these weaker bounds we still achieve the same guarantees when all points satis

H. Löllgen,U. J. Winter,P. Dirschedlhey are log. (. + .) hard to approximate for any constant ., unless ., where . is a constant depending on .. Restricting our attention to approximation factors depending only on ., we show that these problems are .-hard to approximate for any . > 0 unless ., where .′ is some constant depending on ..

Belastungs-EKG: Ischämiediagnostiknode-weighted SNDP. In this paper we describe multiroute-flow based relaxations for the two problems and obtain approximation algorithms for PC-SNDP through them. The approximation ratios we obtain for PC-SNDP are similar to those that were previously known for SNDP via combinatorial algorithms. Spe

Das Ergo-EKG bei Koronarkranken,d the . of the pair. The goal is to find the smallest subgraph . = (.,.) of . in which every pair of vertices .,. is connected by a path contained in .(.,.). We show that the iBGP problem can be reduced to the special case of Constrained Connectivity where . = ... Furthermore, we believe that Constr
