Momentum Accelerated Multigrid Methods

30 Jun 2020 Niu Chunyan Hu Xiaozhe

In this paper, we propose two momentum accelerated MG cycles. The main idea is to rewrite the linear systems as optimization problems and apply momentum accelerations, e.g., the heavy ball and Nesterov acceleration methods, to define the coarse-level solvers for multigrid (MG) methods...
