Feasible direction method for bilevel programming problem
Optimization, 2012In this article, we investigate the application of feasible direction method for an optimistic non-linear bilevel programming problem. The convex lower level problem of an optimistic non-linear bilevel programming problem is replaced by relaxed KKT conditions. The feasible direction method developed by Topkis and Veinott [D.M.

Constrained Variable Metric Method With Feasible Directions
16th Design Automation Conference: Volume 2 — Optimal Design and Mechanical Systems Analysis, 1990Abstract This paper proposes a new feasible direction algorithm based on the constrained variable metric method of Powell in order to handle the design optimization problmes which demand that all iterative points are feasible. The algorithm retains many advantages of the constrained variable metric method, makes use of the properties of ...

A feasible-direction method for nonlinear constrained optimization
ANNALI DELL UNIVERSITA DI FERRARA, 2002The author considers a feasible-direction interior-point technique for the solution of nonlinear differentiable constrained optimization problems which was originally introduced by Herskovits. In the paper several updating rules for the parameters used in the algorithm are introduced and corresponding convergence properties are shown.

A new feasible directions method in nonlinear optimization
1992In each of the mechanical and discrete numerical models presented in the preceding chapters, the solution of a large nonlinear constrained optimization problem is required in order to evaluaute the actual residual stresses in body.

Convergence of methods of feasible directions in extremal problems
USSR Computational Mathematics and Mathematical Physics, 1971Abstract GENERAL theorems on the convergence conditions of one-step iteration methods for minimization problems with constraints are presented. These theorems are applied for the uniform derivation of both previously known and also new results on the convergence of specific methods. The problem of the minimization of the functional f(x) on the set Q

A Method of Feasible Direction with FEM for Shape Optimization
1988The avoidance of cracks in zones of stress concentrations by minimizing the maximal von Mises stress is very important in practical problems for the industry. In many applications it is necessary to allow for the change of traction vectors in large time intervals.

Methods of feasible directions with increased gradient memory
2005The class of feasible directions methods is a powerful tool for solving constrained minimization problems, min-max problems, and unconstrained minimization problems in the absence of continuity of the gradient. The different versions proposed either involve all the gradients and do not require "antizigzagging precautions" or involve only the ...
