Ergebnisse der Exakten Naturwissenschaftenubject to certain degree constraints on the vertices of the subgraph. This paper considers two natural . problems and studies their behavior in terms of approximation algorithms. These problems take as input an undirected graph .?=?(.,.), with |.|?=?. and |.|?=?.. Our results, together with the definition of the two problems, are listed below.

,Hochmolekulare Stoffe in L?sung,We give an .(.)-approximation for minimizing average flow time on unrelated machines, where . is the maximum number of different process times on a machine. Consequently, the ratio is .(log./log.) if all process times are a power of .. Here, . is the ratio of the maximum and minimum process time of a job.
