Preconditioned ADMM with nonlinear operator constraint
(SpringerIFIP Advances in Information and Communication Technology, 2016)
We are presenting a modification of the well-known Alternating Direction Method of Multipliers (ADMM) algorithm with additional preconditioning that aims at solving convex optimisation problems with nonlinear operator ...
Efficient boundary integral solution for acoustic wave scattering by irregular surfaces
(ElsevierEngineering Analysis with Boundary Elements, 2017-10-01)
The left–right operator splitting method is studied for the efficient calculation of acoustic fields scattered by arbitrary rough surfaces. Here, the governing boundary integral is written as a sum of left- and right-going ...
