Die Finsenbehandlung bei Pocken, polynomial time, and we show that for many problems in this family this approximation factor 2 is best-possible (unless P = NP). Special attention is paid to the balanced assignment problem with vector costs, which is shown to be NP-hard even in the highly restricted case of sum costs.

Dynamic Traveling Repair Problem with an Arbitrary Time Window,ddition, we characterize the rate of convergence of the competitive ratio, which approaches 1, as the laxity increases. Specifically, we provide matching lower and upper bounds. These bounds depend on the ratio between the laxity and the optimal TSP solution of the metric space (the minimum distance
