This is the regular Vorlesung Optimierung. I'll talk about rounding problems and linear discrepancy, an area I had a number of results in recently. I you're interested in what I did and what I'll continue to do, feel free to join, but don't feel obliged to do so.
Contents: Linear Discrepany, general rounding is at most twice as bad as rounding halfintegral numbers, theorem of Beck and Fiala, randomized rounding.
