Abstract: Least squares problems appear in many important applications in science and engineering. Recently, there have been many developments in the solution of least squares problems of various kinds. Examples are fast and robust solvers for large scale least squares problems combining Krylov subspace methods with efficient preconditioners such as stationary inner iterations or balanced incomplete factorization. There are also advances in other kinds of least squares problems, such as nonnegative constrained least squares problems, nonlinear least squares problems, total least squares problems and integer least squares problems etc. This mini-symposium will address on recent advances in such areas.
