ISSN: 1572-9125Keywords: 65K05 ; 90C30Source: Springer Online Journal Archives 1860-2000Topics: MathematicsNotes: Abstract An algorithm for semi-inifinite programming using sequential quadratic programming techniques together with anL ∞ exact penalty function is presented, and global convergence is shown. An important feature of the convergence proof is that it does not require an implicit function theorem to be applicable to the semi-infinite constraints; a much weaker assumption concerning the finiteness of the number of global maximizers of each semi-infinite constraint is sufficient. In contrast to proofs based on an implicit function theorem, this result is also valid for a large class ofC 1 problems.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-2878Keywords: Nonlinear optimization ; exact penalty functionsSource: Springer Online Journal Archives 1860-2000Topics: MathematicsNotes: Abstract A sequential quadratic programming algorithm for nonlinear programs using anl ∞-exact penalty function is described. Numerical results are also presented. These results show that the algorithm is competitive with other exact penalty function based algorithms and that the inclusion of the second penalty parameter can be advantageous.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-2894Keywords: semi-infinite programming ; nonlinear optimisation ; L ∞ exact penalty functionSource: Springer Online Journal Archives 1860-2000Topics: Computer ScienceNotes: Abstract A quasi-Newton algorithm for semi-infinite programming using an L ∞ exact penalty function is described, and numerical results are presented. Comparisons with three Newton algorithms and one other quasi-Newton algorithm show that the algorithm is very promising in practice.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-2878Keywords: derivative free optimization ; positive basis methods ; convergence analysis ; frame based methodsSource: Springer Online Journal Archives 1860-2000Topics: MathematicsNotes: Abstract This paper describes a wide class of direct search methods for unconstrained optimization, which make use of fragments of grids called frames. Convergence is shown under mild conditions which allow successive frames to be rotated, translated, and scaled relative to one another.Type of Medium: Electronic ResourceURL:
