Konrad Mundinger

I currently work on (approximately) solving large-scale PDE-constrained optimization problems using dynamic programming and physics-informed neural networks. This brings together many of my research interests, which include but are not limited to: Continuous (convex) optimization, Stochastics, Control Theory, Numerics of PDEs, and (Scientific) machine learning.

🔬 Projects

Decomposition Methods for Mixed-integer Optimal Control

In this project, we study domain decomposition approaches for optimal control in gas transport networks. Our goal is to couple space-time-domain decomposition with machine learning and mixed-integer programming. We will develop NeTI (Network Tearing and Interconnection), a data-driven and physics-informed algorithm combining mixed-integer nonlinear programming, surrogate model learning, and graph decomposition strategies.
