Preconditioning PDE-constrained optimization with -sparsity and control constraints
Margherita Porcelli, Valeria Simoncini, Martin Stoll
PDE-constrained optimization aims at finding optimal setups for partial differential equations so that relevant quantities are minimized. Including sparsity promoting terms in the…
Generalizing diffuse interface methods on graphs: non-smooth potentials and hypergraphs
Jessica Bosch, Steffen Klamt, Martin Stoll
Diffuse interface methods have recently been introduced for the task of semi-supervised learning. The underlying model is well-known in materials science but was extended to graphs…
Preconditioning of a coupled Cahn--Hilliard Navier--Stokes system
Jessica Bosch, Christian Kahle, Martin Stoll
Recently, Garcke et al.[Garcke, Hinze, Kahle, A stable and linear time discretization for a thermodynamically consistent model for two-phase incompressible flow, Applied Numerical…
A Fast Multipole Method based on Band-limited Approximations for Radial Basis Functions
Wei Zhao, Martin Stoll
The meshless/meshfree radial basis function (RBF) method is a powerful technique for interpolating scattered data. But, solving large RBF interpolation problems without fast summat…
