Rate-Distortion Optimization Using Adaptive Lagrange Multipliers [PDF]
IEEE transactions on circuits and systems for video technology (Print), 2019 In current standardized hybrid video encoders, the Lagrange multiplier determination model is a key component in rate-distortion optimization. This originated some 20 years ago based on an entropy-constrained high-rate approximation and experimental ...

Lagrange Multipliers in Infinite Dimensional Spaces, Examples of Application
Encyclopedia of Continuum Mechanics, 2019 The Lagrange multipliers method is used in Mathematical Analysis, in Mechanics, in Economics and in several other fields, to deal with the search of the global maximum or minimum of a function, in presence of a constraint.

Dirichlet boundary value correction using Lagrange multipliers [PDF]
BIT Numerical Mathematics, 2019 We propose a boundary value correction approach for cases when curved boundaries are approximated by straight lines (planes) and Lagrange multipliers are used to enforce Dirichlet boundary conditions. The approach allows for optimal order convergence for

3D non-conforming mesh model for flow in fractured porous media using Lagrange multipliers [PDF]
Computational Geosciences, 2019 This work presents a modeling approach for single-phase flow in 3D fractured porous media with non-conforming meshes. To this end, a Lagrange multiplier method is combined with a parallel variational transfer approach.

Existence of augmented Lagrange multipliers for cone constrained optimization problems
Journal of Global Optimization, 2013 In this paper, by using an augmented Lagrangian approach, we obtain several sufficient conditions for the existence of augmented Lagrange multipliers of a cone constrained optimization problem in Banach spaces, where the corresponding augmenting function

Generalized Optimality Criteria Method for Topology Optimization
Applied Sciences, 2021 In this article, a generalized optimality criteria method is proposed for topology optimization with arbitrary objective function and multiple inequality constraints. This algorithm uses sensitivity information to update both the Lagrange multipliers and
