Moving Least Squares Method for a One-Dimensional Parabolic Inverse Problem
Abstract and Applied Analysis, 2014 This paper investigates the numerical solution of a class of one-dimensional inverse parabolic problems using the moving least squares approximation; the inverse problem is the determination of an unknown source term depending on time.

A Discrete Least Squares Method [PDF]
Mathematics of Computation, 1977 We consider a discrete least squares approximation to the solution of a two-point boundary value problem for a 2mth order elliptic operator. We describe the approximation space of piecewise polynomials and devise a Gaussian quadrature rule that is suitable for replacing the integrals in the usual least squares method.
