Adaptive sampling strategies for risk-averse stochastic optimization with constraints
Beiser, Florian; Keith, Brendan; Urbainczyk, Simon; Wohlmuth, Barbara (Peer reviewed; Journal article, 2023)We introduce adaptive sampling methods for stochastic programs with deterministic constraints. First, we propose and analyze a variant of the stochastic projected gradient method, where the sample size used to approximate ... -
Reducing Numerical Artifacts by Sacrificing Well-Balance for Rotating Shallow-Water Flow
Holm, Håvard Heitlo; Beiser, Florian (Chapter, 2023)We consider the problem of rotational shallow-water flow for which non-trivial rotating steady-state solutions are of great importance. In particular, we investigate a high-resolution central-upwind scheme that is well-balanced ...
