摘要:

An algorithm for approximating solutions of multicriterial nonlinear optimization problems of a class of discontinuous objective functions with disconnected constraint set is proposed in the framework of integral based optimization theory under some weak general assumptions. Numerical examples are given to illustrate the effectiveness of the algorithm

摘要:

An approach to interior methods for linear programming premised on the optimality condition and two fundamental optimization principles (homotopy and symmetry) is described. It provides a concise, yet general introduction to the new area of optimization research germinated by Karmarkar, and a useful alternative to the current logarithmic Barrier-based perspective on the subject

摘要:

We examine the effect of diagonal scaling on the projected gradient method of More and Toraldo [SIAM J. Optimization 1, (1991), pp. 93-114] when the constraints are bound constraints and the quadratic form is positive definite. It is shown that scalings causes the method to visit fewer faces and to minimize the function more quickly. Numerical results are given with the journal bearing problem and some dense matrix bound constrained problems

摘要:

Algorithms for fitting a surface, explicitly or implicitly defined, to some measured points are developed, analyzed and tested. The problem class treated, includes orthogonal regression and errors-in-variables. As a parameter estimation problem only the optimization part of the estimation is treated. Methods using only first order derivatives as well as second order methods are developed and the rich inherent structure of the problem is fully utilized. The main features of the algorithms, that distinguish them from earlier works, are that arbitrary nonnegative weights can be handled and that infinite weights can be used to define nonlinear equality constraints. The local convergence for the first order algorithms is linear for nonzero residual problems and quadratic otherwise. The local convergence for the second order methods is quadratic. A mixed algorithm where only a part of the second derivatives are included is also developed and tested
