Exciting progress on the theory of shape optimization has been made by the research group in Trier University. Daniel Luft and Volker Schulz developed a new approach to address the handling of mesh quality and the optimization of shapes in a unified framework. These so-called pre-shapes extend classical shape space approaches, and permit the formulation of regularizers for general shape optimization problems. With a suitable pre-shape calculus, free form deformations for [...]
Michael Stiglmayr and Onur Tanil Doganay presented at the International Conference on Operations Research 2021 (OR 2021) hosted in Bern (online). The OR Conference is the joint annual conference of the Operations Research Societies of Switzerland ( SVOR ), Germany (GOR e.V.) and Austria (ÖGOR)
Michael Stiglmayr suggested in his talk on “Hypervolume Scalarization for Biobjective Shape Optimization” a scalarization technique which is compatible with non-convex optimization [...]
Johanna Schultes of the GIVEN consortium participated at the Sixth International Conference on Continuous Optimization (ICCOPT) and presented a poster about her current research and the results of the paper with the title: “Gradient Based Biobjective Shape Optimization to Improve Reliability and Cost of Ceramic Components” (see publications).
This conference series is organized every three years and is a flagship conference of the Mathematical Optimization Society (MOS) [...]
Results from the GIVEN-Project were presented at 25th International Conference on MCDM 2019: Beyond the Information Age in Istanbul (Turkey). Johanna Schultes and Onur Tanil Doganay held contributed talks in the session “multiobjective optimization with engineering applications ” with the topics:
- Biobjective Shape Optimization Using Weighted Sums: Probability of Failure versus Costs.
- Gradient-Based Biobjective Shape Optimization: Probability of Failure versus Cost.
Both talks were held on the same shape optimization problem and presented different biobjective solution approaches that were explored in the last year.
The MCDM Conference [...]
The GIVEN consortium visited Siemens in Berlin for its third scientific workshop. Participants from the Universities of Wuppertal and Trier and the Siemens AG came together and discussed the latest progress of the project.
Two members of the GIVEN-Consortium participated in this year’s SIAM Conference on Computational Science and Engineering with the following two contributions:
- Generation of Structured Meshes for Shape Optimization (Contributed talk)
- Blocked Multigrid Methods for Structured Matrices (Poster)
The SIAM CSE conference is a biannual conference run by the Society [...]
Johanna Schultes of the GIVEN consortium participated at the workshop Women in Optimization and presented a poster about results of current research with the topic: “Biobjective Shape Optimization to Improve Reliability and Costs of Ceramic Components using Weighted Sums”.
The workshop series “Women in Optimization” is every two years and addresses young female researchers, doctoral students and mathematical students with focus on optimization and covers the [...]

The GIVEN-Consortium participated in the workshop „Recent Advances in Multi-Objective Optimization 2018“ (RAMOO 2018) in Nantes, France with the contribution „Gradient-Based Biobjective Shape Optimization of Ceramic Components: Probability of Failure versus Cost“. This workshop is a recurring format in the multi-objective optimization community and focuses on the latest advances in exact methods in multi-objective (mixed) integer optimization.
The workshop [...]
The GIVEN consortium met on the last days of November 2018 in Trier for its second scientific workshop. 17 participants from the Universities of Wuppertal and Trier, DLR and Siemens AG came together for two days to discuss progress in the GIVEN project and plan future activities.The workshop program included 9 scientific talks and several discussion rounds. As it is customary in Trier, also a dinner and a wine tasting have been part of the workshop program.
The series of European Consortium for Mathematics in Industry (ECMI) conferences are devoted to enforce the interaction between academy and industry, leading to innovations in both fields. These events have attracted leading experts from business, science and academia, and have promoted the application of novel mathematical technologies to industry.
ECMI conferences are organised under the auspices of the European Consortium for Mathematics in Industry, an association of academic [...]
