Finding directional stationary points of DC programs
Hoai An Le Thi, Van Ngai Huynh, Tao Pham Dinh
We address the problem of computing stationary points for non-smooth, non-convex optimization problems. While this topic is well studied in the smooth setting, fewer algorithmic an…

Directional Hölder Metric Regularity
Van Ngai Huynh, Huu Tron Nguyen, Michel Théra
This paper sheds new light on regularity of multifunctions through various characterizations of directional Hölder /Lipschitz metric regularity, which are based on the concepts of…
