The goal of this project is to implement and study various techniques for the construction of Algebraic Multigrid Methods (AMG) for the solution of positive definite linear systems arising from the discretizations of elliptic partial differential equations (PDEs). Both theoretical as well as practical implementation of the methods that we have developed are based on compatible relaxation and energy minimization
