Erfolgsfaktoren im Stiftungsmanagement is known to be .-hard, but its approximation complexity is not known. For the general problem only an approximation ratio of Õ(n.) has been proved (Kortsarz and Peleg (1993)). In the last years several authors analyzed the case .. In this case Asahiro et al. (1996) showed a constant factor approxim

Lower bounds for on-line scheduling with precedence constraints on identical machines,deterministic algorithms with preemption, and a lower bound of 2 − O(1/.) on the competitive ratio of any randomized algorithm with preemption. All the lower bounds hold even for sequences of unit jobs only. The best algorithm that is known for this problem is the well known List Scheduling algorith

Instant recognition of half integrality and 2-approximations,ver..Problems that are amenable to the analysis provided here are easily recognized. The analysis itself is entirely technical and involves manipulating the constraints and transforming them to a totally unimodular system while losing no more than a factor of 2 in the integrality.
