Optimal Control and Decision Making Under Uncertainty for Digital Twins

Date:

Poster presentation at the IMSI workshop Optimal Control and Decision Making Under Uncertainty for Digital Twins. The poster summarized our work on convex-duality methods and a posteriori error estimates for constrained PDE problems. I presented a convex-duality framework for flow problems subject to flux constraints, covering both the analytical foundations and the numerical realization through finite element discretization. The talk drew on joint work with H. Antil and K. L. A. Kirk.
