[DMANET] IGAFIT Algorithmic Colloquium - 2pm CEST, June 17: Polyhedral Techniques in Combinatorial Optimization by Ola Svensson

Dear all,

we would like to invite you to the IGAFIT Algorithmic Colloquium this
Thursday:

June 17, 2021, 14:00 CEST
Ola Svensson, EPFL
Title: Polyhedral Techniques in Combinatorial Optimization
Abstract: In this talk, we will survey recent use of polyhedral techniques
in combinatorial optimization. In particular, we introduce techniques for
using linear programming formulations, even exponential-sized ones, to
extract structure from problem instances that guides the design of
algorithms.
The talk will focus on two results: a constant-factor approximation
algorithm for the asymmetric traveling salesman problem and a deterministic
parallel algorithm for the perfect matching problem. The so-called laminar
structure of the considered linear programming formulations plays a central
role in both these results.
Finally, we discuss several intriguing research directions and open
questions related to these problems.


We would like to invite you to take part in the event including the
networking session. This new event aims to integrate the European
algorithmic community and keep it connected during the times of the
pandemic. The meeting will be held using the Airmeet platform and to attend
please go to https://www.airmeet.com/e/649d9310-cdc2-11eb-847d-79adba337a09.
You can find more information about the talk on IGAFIT web page:
http://igafit.mimuw.edu.pl/?page_id=483786.

In order to access the Airmeet platform, you will need to register, so that
others know who you are. Then before and after the talk, you will be
located inside a Social Lounge, where discussion tables are visible. Most
of the tables can have up to 8 chairs, and you can join a table by clicking
the "Take a Seat" button on a table. This way you will be able to talk to
people seated currently at the table. When the session starts you will be
automatically switched to see the stage. You can find more instructions on
how to use Airmeet here:

We invite you to take part in the event. Please advertise broadly and bring
your students/postdocs as well.
