    Preconditioners for the conjugate gradient algorithm using Gram-Schmidt and least squares methods
    (2007-1)
    Straubhaar, Julien 
    This paper is devoted to the study of some preconditioners for the conjugate gradient algorithm used to solve large sparse linear and symmetric positive definite systems. The construction of a preconditioner based on the Gram-Schmidt orthogonalization process and the least squares method is presented. Some results on the condition number of the preconditioned system are provided. Finally, numerical comparisons are given for different preconditioners.
