摘要

In this paper, we introduce and study new notions of directional Levitin–Polyak well-posedness for both optimization problems and variational inequalities. First, we establish necessary and sufficient conditions for these directional Levitin–Polyak well-posednesses. Then, we show a close relationship between the directional Levitin–Polyak well-posedness of optimization problems and that of variational inequalities. In addition, we present several examples to illustrate the advantages of our results over existing ones in the literature.
