Optimality conditions for mathematical programs with orthogonality type constraints
Sebastian Lämmel, Vladimir Shikhman
We consider the class of mathematical programs with orthogonality type constraints (MPOC). Orthogonality type constraints appear by reformulating the sparsity constraint via auxili…

Cardinality-constrained optimization problems in general position and beyond
Vladimir Shikhman, Sebastian Lämmel
We study cardinality-constrained optimization problems (CCOP) in general position, i. e. those optimization-related properties that are fulfilled for a dense and open subset of the…
