Dear scheduling researcher, We are delighted to announce the talk given by Lars Rohwedder (Maastricht University). The title is " Recent advances in flow time scheduling ". The seminar will take place on Zoom on Wednesday, January 18 at 14:00 UTC.

Flow time is one of the most natural metrics to optimize in scheduling, but algorithmically it can be notoriously difficult to handle. I will talk about some recent advances in this topic, focusing on two results by myself and co-authors: a PTAS for the sum of weighted flow times on a single machine and improved approximation guarantees for parallel unrelated machines. The first result is enabled by a study of structural properties of constraints in a natural ILP formulation and the second result relies on a novel connection to discrepancy theory. The next talk in our series will be: Jacques Carlier (Sorbonne University) | February 1 | Constructive and destructive bounds for the m-machine scheduling problem.
