Numerical experiments to optimize the use of (I)LU preconditioning in the iterative linear solver package LINSOL

In the iterative linear solver package LINSOL several generalized conjugate gradient (CG) methods (or, briefly, CG-type methods) with quite different properties are implemented. With these methods polyalgorithms with automatic method switching are constructed. The “emergency exit” that is taken in t...
