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…

Stochastic Difference-of-Convex Algorithms for Solving nonconvex optimization problems
Le Thi Hoai An, Huynh Van Ngai, Pham Dinh Tao +1
The paper deals with stochastic difference-of-convex functions (DC) programs, that is, optimization problems whose the cost function is a sum of a lower semicontinuous DC function…
