Lifted multicuts on paths: combinatorial optimization and polyhedral geometry

Date: Tuesday, September 11, 2018 16:00 - 18:00
Speaker: Dominik Schröder (IST Austria)
Location: Big Seminar room Ground floor / Office Bldg West (I21.EG.101)
Series: Mathematics and CS Seminar
Host: Laszlo Erdös
Lab building west seminar room

Abstract:

In this talk we define the concept of lifted multicuts and study polyhedral techniques for their combinatorial optimisation. While the problem is NP-hard for most graphs (including trees), we present results on the facet-defining inequalities for the case of paths. Potential applications include time series segmentation, e.g. word separation in speech recordings.
