Event information

Description

This seminars aims at bringing researchers in optimal control and numerical mathematics together for a week of recent research results, collaboration and – most importantly – ample time for in-depth discussions. Additionally, snowboarding as well as cross-country and alpine skiing can be practiced (or learned) on site.

Organization

The seminar has previously been organized by Roland Herzog’s numerical mathematics group at the TU Chemnitz and has since moved to his Scientific Computing and Optimization group at the University of Heidelberg. Feel free to visit last year’s edition’s website here.

Location and housing

The seminar will again take place at Hotel Gürtl" (" Hotel on google maps) in Haus im Ennstal, Austria. The cost per participant is dependent on the chosen rooming option and this year’s pricing is as follows:

  • Accomodation including breakfast and dinner per person and night at
    • 139€ in a standard double room when shared
    • 146€ in a “comfort” double room when shared
    • 164€ in a single room
  • 15€ seminar attendance fee per day and person (max of 5 days) and
  • 2,50€ per night local overnight tax.

Talks

We would like to make the slides corresponding with the talks available to all participants. Please, once you have given your presentation, upload your slides to the folder where you will then also be able to access the other participants’ slides, i.e., here (password will be given out at the event).

Pictures

If you would like to share some of your pictures with the other participants, feel free to upload them to the folder where you can also download the other participants’ pictures, i.e., here (password will be given out at the event).
