The danger of iteration methods [PDF]
Journal de Physique Lettres, 1983 When a Hamiltonian K depends on variables ϕi, the values of these variables which minimize K satisfy the equations ∂K/∂ϕ i = 0. If this set of equations is solved by iteration, there is no guarantee that the solution is the one which minimizes K.

Nonlinear Preconditioning: How to use a Nonlinear Schwarz Method to Precondition Newton's Method [PDF]
, 2015 For linear problems, domain decomposition methods can be used directly as iterative solvers, but also as preconditioners for Krylov methods. In practice, Krylov acceleration is almost always used, since the Krylov method finds a much better residual ...

A method of parallel iteration
Journal of Computational and Applied Mathematics, 1989 AbstractA method of parallel iteration for large systems of linear equations based on coarse mesh rebalance procedures is described. Multiplicative and additive forms of correction are applied and tested. Finally a hybrid correction stencil is introduced. Some matrix properties of intermediate linear systems are considered.

Many-body effects and matrix inversion in low-Reynolds-number hydrodynamics [PDF]
, 2001 It is shown that the method of reflections in resistance form (with truncated multipoles) is one of many possible iterative methods to obtain the inverse of the mobility matrix (with the same truncation) in low-Reynolds-number hydrodynamics. Although the
