We analyse the efficiency of a class of iterative methods for solving large scale convex quadratic programs. These methods, known as splitting methods and projection methods, require to solve a sequence of easy strictly convex quadratic programming subproblems obtained by splitting the matrix of the objective function. We describe in details the techniques used for generating the large and sparse test problems on which the computational behaviour of the methods is studied.

Abstract
We analyse the efficiency of a class of iterative methods for solving large scale convex quadratic programs. These methods, known as splitting methods and projection methods, require to solve a sequence of easy strictly convex quadratic programming subproblems obtained by splitting the matrix of the objective function. We describe in details the techniques used for generating the large and sparse test problems on which the computational behaviour of the methods is studied.
