Abstract: For an $ n$th order linear boundary value problem $ Lf = {g_0}$ in the Hilbert space $ {L^2}[a,b]$, a sequence of approximate solutions is constructed which converges to the unique least squares solution of minimal norm. The method is practical from a computational viewpoint, and it does not require knowing the null spaces of the differential operator $ L$ or its adjoint $ {L^ \ast }$.
