Free disposal hull condition to verify when efficiency coincides with weak efficiency
The paper gives a condition to verify when efficiency coincides with weak efficiency when the free disposal hull of the set is convex and presents four classes of optimization problems where this characterization holds. The main theorem the authors give is applied to the least absolute shrinkage and selection operator (LASSO) showing that for a multi-objective version of LASSO, all weakly efficient solutions are efficient. Numerical simulation demonstrates that this equivalence is helpful to accelerate the hyper-parameter search for LASSO.
