A nonsmooth primal-dual method with interwoven PDE constraint solver
Bjørn Jensen, Tuomo Valkonen
We introduce an efficient first-order primal-dual method for the solution of nonsmooth PDE-constrained optimization problems. We achieve this efficiency through not solving the PDE…

Acousto-Electric Tomography with Total Variation Regularization
Bolaji James Adesokan, Bjørn Jensen, Bangti Jin +1
We study the numerical reconstruction problem in acousto-electric tomography of recovering the conductivity distribution in a bounded domain from interior power density data. We pr…
