Ein Konstruktionsverfahren bei allgemeiner linearer Approximation

In order to solve the linear approximation problem the Remes-algorithm is quite suitable in case of a Haar subspace. Without this assumption one must modify the algorithm even to ensure the practicability (cf. [8]). In this paper, a modification, in some respect similar to that in [8], will be given which is always practicable and the convergence of which is proved, too. The relation to the Remes-algorithm will be evident from a geometrical interpretation.
