A DC-Reformulation for Gradient- $L^{0}$ -Constrained Problems

Bastian Dittrich, Evelyn Herberg, Roland Herzog +1

Cardinality constraints in optimization are commonly of $L^{0}$ -type, and they lead to sparsely supported optimizers. An efficient way of dealing with these constraints algorithmical…

The Largest- $K$ -Norm for General Measure Spaces and a DC Reformulation for $L^{0}$ -Constrained Problems in Function Spaces

Bastian Dittrich, Daniel Wachsmuth

We consider constraints on the measure of the support for integrable functions on arbitrary measure spaces. It is shown that this non-convex and discontinuous constraint can be equ…
