Abstract
Solutions of linear systems of equations are often known in advance to belong to some closed convex set B⊆Rn. This information leads to certain constraining strategies in iterative solution algorithms, such as the (nonlinear) projection of iterates onto B. Convergence of resulting iterative processes and their limits are studied.Keywords
