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 ...

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 ...
