MGCNN: a learnable multigrid solver for sparse linear systems from PDEs on structured grids
Yan Xie, Minrui Lv, Chensong Zhang
This paper presents a learnable solver tailored to iteratively solve sparse linear systems from discretized partial differential equations (PDEs). Unlike traditional approaches rel…
