Let X, Y be normed linear spaces, T β L(X, Y ) be a bounded linear operator from X to Y . One wants to solve the linear problem Ax = y for x (given y β Y ), as well as one can. When A is invertible, the unique solution is x = A -1 y. If this is not the case, one seeks an approximate solution of the
