Exponential Stability of Partial Primal-Dual Gradient Dynamics with Nonsmooth Objective Functions
Zhaojian Wang, Wei Wei, Changhong Zhao +3
In this paper, we investigate the continuous time partial primal-dual gradient dynamics (P-PDGD) for solving convex optimization problems with the form $ \min\limits_{x\in X,y\inΩ}…
