Accelerated Proximal Gradient Methods in the affine-quadratic case: Strong convergence and limit identification
Walaa M. Moursi, Andrew Naguib, Viktor Pavlovic +1
Recent works by Bot-Fadili-Nguyen (arXiv:2510.22715) and by Jang-Ryu (arXiv:2510.23513) resolve long-standing iterate convergence questions for accelerated (proximal) gradient meth…

MGProx: A nonsmooth multigrid proximal gradient method with adaptive restriction for strongly convex optimization
Andersen Ang, Hans De Sterck, Stephen Vavasis
We study the combination of proximal gradient descent with multigrid for solving a class of possibly nonsmooth strongly convex optimization problems. We propose a multigrid proxima…
