SCAIM Seminar: Multilevel preconditioners for simulations and optimization on dynamic, adaptive meshes
For the efficient solution of large, sparse, linear systems of equations, Ax = b, we usually need a preconditioning matrix P, in an appropriate sense close to the inverse of A, such that solving PAx = Pb converges fast. If we need to solve a sequence...
