Least-Squares Methods for Linear Elasticity [PDF]
SIAM Journal on Numerical Analysis, 2004 Summary: This paper develops least-squares methods for the solution of linear elastic problems in both two and three dimensions. Our main approach is defined by simply applying the \(L^2\) norm least-squares principle to a stress-displacement system: the constitutive and the equilibrium equations.

Nonlinear least squares method
Communications, 1999 The paper deals with a comparison of linear and nonlinear least squares approximation. Its aim is to show that the well known transformations of nonlinear dependencies on linear dependencies do not always give exact results.

Solution of the Least Squares Method problem of pairwise comparison matrices [PDF]
, 2008 The aim of the paper is to present a new global optimization method for determining all the optima of the Least Squares Method (LSM) problem of pairwise comparison matrices. Such matrices are used, e.g., in the Analytic Hierarchy Process (AHP).
