New results on approximate solution in two-level optimization
P. Loridan, Jacqueline Morgan · Optimization · 1989
This paper is a continuation of a recent work on two level optimization problems that we have submitted in [11]. We improve and extend approximation results that we obtained for a approximate solutions. By considering an ε-regularized problem, together with convexity assumptions in the lower level, we get some new interesting properties and, in particular, an existence result for the solutions to the regularized problem.
