摘要：
Methods of iterative solution in Krylov subspaces are considered for systems of linear algebraic equations with positive definite nonsymmetric real matrices A, where directing (correcting) vectors and residual vectors possess different properties of A-semiconjugacy or orthogonality. Variational and projective properties of some variants of such algorithms and the possibility to use dynamic preconditioners are described. Results of numerical experiments are presented.
