Two-level trust-region method with random subspaces
Andrea Angino, Alena KopaniÄáková, Rolf Krause
We introduce a two-level trust-region method (TLTR) for solving unconstrained nonlinear optimization problems. Our method uses a composite iteration step, which is based on two dis…

The limitations of a standard phase-field model in reproducing jointing in sedimentary rock layers
Edoardo Pezzulli, Patrick Zulian, Alena KopaniÄáková +2
Geological applications of phase-field methods for fracture are notably scarce. This work conducts a numerical examination of the applicability of standard phase-field models in re…
