,Über die alveoläre Lungenproteinose,, we introduce a common generalization of both the classical flow over time model and Melkonian’s model. Secondly, we present a non-trivial extension of an FPTAS by Fleischer and Skutella to our new flow model. Prior to this, no approximation algorithm was known for Melkonian’s model.

The Physiology of growth Hormone,died broadcast scheduling problems. However, the specific requirements of the applications motivate some generalizations and variants of previously studied metrics for broadcast scheduling. We consider both online and offline versions of these problems and provide new algorithms and results.

Die rheumatische Infektion im Kindesalter,SPT, is not better than 1.243. This constitutes the first lower bound for WSEPT in this setting, and in particular, it sheds new light on the fundamental differences between deterministic and stochastic scheduling problems.

A. Czerny,F. Kraus,A. SchittenhelmWe study the problem of producing a global ranking of items given pairwise ranking information, when the items to be ranked arrive in an online fashion. We study both the maximization and the minimization versions of the problem on tournaments (max acyclic subgraph, feedback arc set). We also study the case when the items arrive in random order.
