Exponential augmented Lagrangian methods for equilibrium problems

Optimization Methods and Software, 2020
We introduce exponential augmented Lagrangian methods for solving equilibrium problems in finite-dimensional spaces, extending the so-called quadratic augmented Lagrangian methods.

Approximation of the capillarity problem by an augmented lagrangian method

Numerical Algorithms, 1996
The author proposes an algorithm to compute an approximation of capillary surfaces in a gravitational field. The algorithm is based on a decomposition-coordination method by augmented Lagrangians and the discretization is done using the finite element method.

Coevolutionary augmented Lagrangian methods for constrained optimization

IEEE Transactions on Evolutionary Computation, 2000
This paper introduces a coevolutionary method developed for solving constrained optimization problems. This algorithm is based on the evolution of two populations with opposite objectives to solve saddle-point problems. The augmented Lagrangian approach is taken to transform a constrained optimization problem to a zero-sum game with the saddle point ...

Accelerated augmented Lagrangian method for image reconstruction

2013 International Conference on Wireless Communications and Signal Processing, 2013
In this paper, an efficient image reconstruction algorithm based on compressed sensing (CS) in the wavelet domain is proposed. The new algorithm is composed of three steps. Firstly, the image is represented with its coefficients using the discrete wavelet transform (DWT). Secondly, the measurement is obtained by using a random Gaussian matrix. Finally,
