OptALI Summer School on Optimization with focus on Robust Optimization, 27-31 August 2012, Göttingen

The  OptALI team of the University of Göttingen is happy to announce  a summer school on (robust) optimization and its applications in August 2012. It especially addresses the members of the OptALI Project but it is also open to other young researchers.

The 2012 OptALI summer school covers different topics on optimization such as integer programming, multi-objective optimization and column generation. A special focus is given to robustness and planning under uncertainty, mainly on the Thursday and Friday.


Prof. Anita Schöbel and the research group of optimization at the Institute of Numerical and Applied Mathematics at the University of Göttingen.


Important: The registration fee has been reduced from 60€ to 30€, but does not include lunch anymore!

There will be a registration fee of 30€ to cover expenses for the organisation. It includes the social event with a barbecue and coffee breaks. The fee is payable in cash on the first day of the workshop. Please note that we can accept Euros only.
For registration and further information please contact Robert Schieweck (r.schieweck at math.uni-goettingen.de).

We are looking forward to seeing you in Göttingen!
