The First Problem of Algebraic Regression,The optimisation problem which appears in treating underdetermined linear system equations and weakly nonlinear system equations is a standard topic in many textbooks on optimisation.

The Fifth Problem of Algebraic Regression: The System of Conditional Equations: Homogeneous and InhTwo systems of poor inconsistent conditional equations are treated, namely homogeneous and inhomogeneous inconsistent equations. The least squares solution with respect to the .-norm is derived in the homogeneous case and the corresponding least squares solution with respect to the .-seminorm in the inhomogeneous case.

The Sixth Problem of Generalized Algebraic Regression,Variance–covariance component estimation of Helmert–type is presented in the Gauss–Helmert model. The basis result is the construction of a local Helmert–type inhomogeneous, invariant, quadratic and unbiased estimator of variance–covariance components.

Integer Least Squares,In this chapter the general mixed integer linear model is introduced and its background in application for the Global Navigation Satellite Systems (GNSS) is described. The fitting of such models is reduced to the integer least squares problem. The principles of solving integer least squares problem are explained and the LLL algorithm is presented.
