Webb2.2 Proximal point method and its worst-case rates Proximal point method was first introduced to convex optimization by Martinet [46], which is based on the proximal mapping by Moreau [49]. The method was later extended to monotone inclusion problem by Rockafellar [59]. The proximal point method for maximally monotone operators … Webb2. Block proximal (scheme 2) can stabilize iterates Each limit point is a critical point (Grippo and Sciandrone’00); Global convergence for non-convex problems is unknown; 3. Block proximal linearization (scheme 3) is often easiest Very few works use this scheme for non-convex problems yet; Related to the coordinate gradient descent method ... kmov breaking news crime
