The authors consider an adaptive greedy method, with slow linear convergence, in order to solve very large and at the same time, very general collocation problems. The method is a nonstandard one not directly aimed at a solution of the partial differential equation problems. In spite of this, the authors carry out some numerical results corresponding to the Dirichlet boundary value problem for the Poisson equation.
