CO@Work 2024

Computational Optimization at Work


The summer school CO@Work 2024 will be held from September 16 to 27, 2024, at Zuse Institute Berlin and is organized jointly by TU Berlin, HTW Berlin, and Zuse Institute Berlin, and co-sponsored by MATH+, BMS, Forschungscampus MODAL, I²DAMO, GOR, DFG Priority Program 2298, COPT, d-fine, FICO, GAMS, and Gurobi.

This block course addresses everyone interested in the use of computational optimization and mathematical programming in concrete applications from practice, in particular advanced masters students, PhD students, and post-docs.

CO@Work2024 will be the seventh incarnation of this workshop series, and the fifth one being held in Berlin.


We will start with an opening session and welcome reception on Monday. The other days will follow the template schedule with lectures in the morning and hands-on exercises in the afternoon. A social dinner is planned for Friday evening, Sep 20. The precise day of the excursion during the second week is still tentative.

The examination for all students that participated on-site and wish to obtain a 10 ECTS certificate will be held one week after the summer school, Oct 7 15:00-17:00. The exam will be on-site for students from Berlin universities (in room MA004 at TU Berlin's math building) and remotely for other participants.

There are good and bad news. The bad news first: The application for the in-person event is currently closed because we have reached our capacity limit. If spots become available, we will contact people on our waiting list. That being said, if you cannot join CO@Work for any unforeseen reasons, please let us know so we can pass your spot along.

The good news: There will be a limited (!) online version of CO@Work. Online participants will have the possibility to:

  • view all* lectures as a stream in a Zoom Webinar (*=provided the lecturer's permission)
  • ask questions via Zoom's Q&A capabilities
Online participants will not have the opportunity to:
  • join the hand's-on tutorials
  • participate in the networking events or the excursion
  • receive any ECTS certificates
  • enjoy late summer in sunny Berlin
If you would like to join CO@Work online, please register here:

Online participation is free. The registration fee for on-site participation will be 100 EUR per participant, waived for students from Berlin universities. The language of the course is English.


There are only few hotels within less than half an hour walking distance of ZIB, those are listed below. If those are booked, we recommend to look for accommodation close to the subway line U3, the bus line X83 or the bus line 101, all of which have a stop close to ZIB.
Please note that September 28/29 is the weekend of the Berlin Marathon, so it is probably a good idea to book as soon as possible, in particular if you wish to stay beyond the last Friday.
