How Stringent is the Linear Independence Kink Qualification in Abs-Smooth Optimization?
Lukas Baumgärtner, Franz Bethke, Ganna Shyshkanova +1
Abs-smooth functions are given by compositions of smooth functions and the evaluation of the absolute value. The linear independence kink qualification (LIKQ) is a fundamental assu…
