  1. RA-DCA: A Randomized Active-Set DCA for Directional Stationarity in Max-Structured DC Programs

    Researchers have introduced RA-DCA, a novel algorithm designed to address challenges in nonsmooth difference-of-convex (DC) programming. This method employs a randomized active-set approach to ensure directional stationarity, a crucial property for convergence in optimization problems. RA-DCA projects active gradients onto sampled directions and uses a linear program as a fallback, significantly reducing computational cost compared to exact active-vertex screening. AI
