GPU-accelerated superiorization on constrained physical problems with SupPy
Tobias Becher, Yair Censor, Kay Barshad +1
The superiorization method (SM) is situated between feasibility-seeking and constrained optimization. Instead of aiming at the minimum of a given objective function over a constrai…

A high-order deterministic dynamical low-rank method for proton transport in heterogeneous media
Pia Stammer, Niklas Wahl, Jonas Kusch +1
Dose calculations in proton therapy require the fast and accurate solution of a high-dimensional transport equation for a large number of (pencil) beams with different energies and…

A Deterministic Dynamical Low-rank Approach for Charged Particle Transport
Pia Stammer, Tiberiu Burlacu, Niklas Wahl +2
Deterministically solving charged particle transport problems at a sufficient spatial and angular resolution is often prohibitively expensive, especially due to their highly forwar…
