✦ Synopsis

Communicated by E. Y. Rodin

Al~ract--We consider linear feasibility problems in the "standard" form Ax = b, I ~< x ~< u. The successive orthogonal projections method may be used for solving this problem using sparse orthogonal factorizations techniques for computing the projections on Ax = b. We introduce an acceleration technique in order to speed up the (generally slow) convergence of the method. We present some numerical experiments.

The paper discusses an iterative scheme for solving large-scale three-dimensional linear elasticity problems, discretized on a tensor product of two-dimensional and one-dimensional meshes. A framework is chosen of the additive AMLI method to develop a preconditioner of a `black-box' type which is ro
