The paper deals with a cascadic conjugate-gradient method (shortly called the CCCalgorithm) which was proposed by P. Deufihard and can be considered as a simpler version of a multigrid (multilevel) method. We define it recurrently for discrete self-adjoint positive-definite problems on a sequence of
