Augmented lagrangians and sphere packing problems
(Taylor & Francis LtdAbingdonInglaterra, 1998)
New Optimization Algorithms for Structural Reliability Analysis
(TECH SCIENCE PRESSNORCROSS, 2012)
Solution of structural reliability problems by the First Order method require optimization algorithms to find the smallest distance between a limit state function and the origin of standard Gaussian space. The Hassofer-L ...
BOX-QUACAN and the implementation of Augmented Lagrangian algorithms for minimization with inequality constraints
(Springer HeidelbergHeidelbergAlemanha, 2000)
Augmented lagrangians with adaptive precision control for quadratic programming with equality constraints
(SpringerNew YorkEUA, 1999)
Augmented Lagrangian methods under the constant positive linear dependence constraint qualification
(SPRINGER, 2008)
Two Augmented Lagrangian algorithms for solving KKT systems are introduced. The algorithms differ in the way in which penalty parameters are updated. Possibly infeasible accumulation points are characterized. It is proved ...
Coevolutionary Genetic Algorithm Based on the Augmented Lagrangian Function for Solving the Economic Dispatch Problem
(2015-10-01)
This paper proposes a coevolutionary augmented Lagrangian method (AGCE) for solving the classic economic dispatch problem. This problem becomes non-convex and non-differentiable if valve-point loadings effects are considered ...
On the cost of solving augmented Lagrangian subproblems
(Springer, 2020-07)
At each iteration of the augmented Lagrangian algorithm, a nonlinear subproblem is being solved. The number of inner iterations (of some/any method) needed to obtain a solution of the subproblem, or even a suitable approximate ...
An augmented Lagrangian technique combined with a mortar algorithm for modelling mechanical contact problems
(Wiley, 2013-01)
A finite element formulation for three dimensional (3D) contact mechanics using a mortar algorithm combined with a mixed penalty-duality formulation from an augmented Lagrangian approach is presented. In this method, no ...
Analysis of semicoercive contact problems using symmetric BEM and augmented Lagrangians
(Elsevier Sci LtdOxfordInglaterra, 1996)
Numerical solutions for frictional contact problems based on a mortar algorithm with an augmented Lagrangian technique
(Springer, 2015-12)
This work presents a frictional contact formulation to solve three-dimensional contact problems with large finite displacements. The kinematic description of the contacting bodies is defined by using a mortar approach. The ...
