abstract = {<p style="text-align: justify;">In this article, a level-set approach for solving nonlinear elliptic Cauchy problems with piecewise constant solutions is proposed, which 
allows the definition of a Tikhonov functional on a space of 
level-set functions. We provide convergence analysis for the 
Tikhonov approach, including stability and convergence results. Moreover, a numerical investigation of the proposed Tikhonov regularization
method is presented. 
Newton-type methods are used for the solution of the optimality systems, 
which can be interpreted as stabilized versions of algorithms in a previous
work and yield a substantial improvement in performance. The whole approach is focused on three dimensional models, better suited 
for real life applications.</p>},
