| Abstract: | This paper is concerned with the (preconditioned) conjugate gradient method for solving systems of linear algebraic equationsAx=b withA having Red/Black form. The connections between the Conjugate Gradient (CG) scheme applied toAx=b and its two reduced systems are explored under certain conditions. |
