The Dutch Seminar on Optimization is an initiative to bring together researchers from the Netherlands and beyond, with topics that are centered around Optimization in a broad sense. We would like to invite all researchers, especially also PhD students, who are working on related topics to join the events.

Title:
Primal-dual approximation framework for weighted integer covering problems.
Abstract:
We present a general approximation framework for weighted integer covering problems. In a weighted integer covering problem, the goal is to determine a non-negative integer solution x to system Ax ≥ r minimizing a non-negative linear cost function c. We analyze the performance of two commonly used primal-dual algorithms (greedy dual and dual fitting) on some restricted systems (A, r) that we call greedy systems. We also study the impact of truncation, i.e. a scheme for improving the IP formulation of the problem. (Joint work with Jose Verschae, Niklas Rieken, and Andreas Wierz.)
