The NATO complex examine Institute on "Algorithms for non-stop optimiza­ tion: the cutting-edge" was once held September 5-18, 1993, at II Ciocco, Barga, Italy. It used to be attended through seventy five scholars (among them many renowned experts in optimiza­ tion) from the next international locations: Belgium, Brasil, Canada, China, Czech Republic, France, Germany, Greece, Hungary, Italy, Poland, Portugal, Rumania, Spain, Turkey, united kingdom, united states, Venezuela. The lectures got through 17 renowned experts within the box, from Brasil, China, Germany, Italy, Portugal, Russia, Sweden, united kingdom, united states. fixing non-stop optimization difficulties is a basic job in computational arithmetic for functions in components of engineering, economics, chemistry, biology and so forth. so much genuine difficulties are nonlinear and will be of relatively huge dimension. Devel­ oping effective algorithms for non-stop optimization has been an enormous box of analysis within the final 30 years, with a lot extra impetus supplied within the final decade via the provision of very quick and parallel pcs. suggestions, just like the simplex strategy, that have been already thought of totally built thirty years in the past were completely revised and significantly better. the purpose of this ASI was once to offer the state-of-the-art during this box. whereas now not all very important facets may be coated within the fifty hours of lectures (for example multiob­ jective optimization needed to be skipped), we think that almost all vital subject matters have been provided, lots of them via scientists who significantly contributed to their development.

The algorithm can be generalized in a straightforward way to rank deficient A and B. For details see Paige [44]. The algorithm as described here requires a total of about 2m 3 /3 + m 2 n flops.

In the simplest constrained least squares problem the solution is required to satisfy a subsystem of equations exactly. In Section 3 we compare three different methods for solving such problems. An important technique for regularizing ill-conditioned least squares problems is to include a quadratic inequality constraint. In Section 4 we give an overview of methods for solving such constrained problems. Sparse least squares problems are treated in Sections 5 and 6. The symbolic phase of the computation is covered in Section 5 and the numerical phase in Section 6.
