<p

lang="en-US">The goal of this project is the development of
stochastic gradient
methods for the treatment of almost sure state constraints. Such
constraints
arise for example in the nomination validation of gas networks
under uncertain
demands but also play a role in the transition towards future
hydrogen
networks. A focus of the project is the consideration of sequences
of relaxed
problems intertwined with the stochastic gradient method and a
rigorous
mathematical convergence analysis of the resulting methods.</p>

lang="en-US">We are looking for candidates with a master’s degree
in mathematics
or a closely related field with a strong background in
optimization and partial
differential equations. Prior knowledge in stochastic
optimization, optimal
control, or stochastic analysis is beneficial.</p>
