https://doi.org/10.1007/978-3-8350-5553-7.-median..We also give a 34-approximation for the knapsack median problem, which greatly improves the approximation constant in . Using the same technique, we also give a 9-approximation for matroid median problem introduced in , improving on their 16-approximation.

Efficient Sampling Methods for Discrete Distributionsoth problems, we present on two different classes of inputs – sorted and general probabilities – efficient preprocessing algorithms that allow for asymptotically optimal querying, and prove almost matching lower bounds for their complexity.

Improved LP-Rounding Approximation Algorithm for ,-level Uncapacitated Facility Locationding builds upon the technique of iteratively rounding fractional solutions on trees (Garg, Konjevod, and Ravi SODA’98) originally used for the group Steiner tree problem..We improve the approximation ratio for .-UFL for all . ≥ 3, in particular we obtain the ratio equal 2.02, 2.14, and 2.24 for . = 3,4, and 5.

Kostensenkung bei indirekten Materialien,gree distributions which trades accuracy for tractability. In particular, our bounds only require the solution of a 1-dimensional optimization problem (which typically turns out to be very easy) and as such can be used to compute explicit rigorous unsatisfiability bounds.
