The 5th workshop of the cooperation between ZIB and the Institute of Statistical Mathematics (ISM) Tokyo and the Institute of Mathematics for Industry of Kyushu University, established in 2016, was held at the MODAL research campus from 27-09-30-21, for the first time as a virtual workshop due to the pandemic situation. Another sponsor was RIKEN, Japan’s largest interdisciplinary research institution. Almost 50 lectures on the topics of the MODAL Labs formed the scientific program of the workshop. Speakers came from...Read More
“INFORMS Journal of Computing”, one of the most prestigious journals for the publication of research articles in the field of mathematical optimization, regularly honors outstanding publications with the “Meritorious Paper Award”. Recently, two ZIB researchers, Dr. Timo Berthold and Mr. Jakob Witzig, had the honor to receive this award. The award-winning article describes how to transfer a technique called “conflict analysis” from linear optimization to non-linear optimization. The results are implemented in the non-linear optimization solver SCIP developed at the...Read More
The “Mixed Integer Programming Workshop” is an annual event that features recent contributions in the field of MIP. Every year, a comitee honors the best contribution to the poster session with a best poster award. The work presented by Leon Eifler integrates important techniques such as presolving, primal heuristics, and certification of results into the existing state of the art exact MIP solver SCIP. The computational study shows that this helps in closing a significant part of the gap between...Read More
