About the SCIP Workshop

We are happy to announce our upcoming SCIP Workshop from September 30 to October 2, 2014. It is intended for

  • students (undergraduate and graduate) and researchers who would like to know more about SCIP, and
  • researchers who already use SCIP and want to share their experiences.

The main focus of the workshop is to provide a forum for current and prospective SCIP users to discuss their applications and share their experience with SCIP. Therefore, we invite you to participate and to give an approximately 30-minute talk on your research. There will be 10 minutes of discussion after every presentation.

The first day of the workshop will be dedicated to a hands-on introduction into the SCIP Optimization Suite, followed by two days of scientific talks, including a plenary talk by Andrea Lodi from the University of Bologna on October 2 and talks by developers of the SCIP Optimization Suite about their research.

While we recommend participants to attend the complete workshop, it is also possible to attend only the introduction day or only the final two days of scientific talks.


The workshop will be free of charge and take place at Zuse Institute Berlin, Takustr. 7, Berlin

If you want to attend the workshop, please write to by August 25, 2014, and let us know if you are planning to give a talk and whether you want to participate in the SCIP introduction on September 30.
