Lagrangian Relaxation Method for the Step fixed-charge Transportation Problem
In this paper, a step fixed charge transportation problem is developed where the products are sent from the sources to the destinations in existence of both unit and step fixed-charges. The proposed model determines the amount of products in the existing routes with the aim of minimizing the total cost (sum of unit and step fixed-charges) to satisfy the demand of each customer. As the problem i...
متن کاملNew Bundle Methods for Solving Lagrangian Relaxation Dual Problems
Bundle methods have been used frequently to solve nonsmooth optimization problems. In these methods, subgradient directions from past iterations are accumulated in a bundle, and a trial direction is obtained by performing quadratic programming based on the information contained in the bundle. A line search is then performed along the trial direction, generating a serious step if the function va...
متن کاملLagrangian Relaxation for Integer Programming
It is a pleasure to write this commentary because it offers an opportunity to express my gratitude to several people who helped me in ways that turned out to be essential to the birth of [8]. They also had a good deal to do with shaping my early career and, consequently, much of what followed. The immediate event that triggered my interest in this topic occurred early in 1971 in connection with...
متن کاملReALE - Reconnection-based Multimaterial Arbitrary Lagrangian-Eulerian Method Mimetic Methods for Partial Differential Equations
The need of the office of science programs to approximate the solutions of strongly nonlinear,coupled partial differential equations in complex domains has been a continuous driver for the dualdevelopment of supercomputing platforms and for more accurate and efficient numerical algorithms.Despite the years and magnitude of the effort that has been put into computational science, in ...
متن کاملLagrangian Formalism for Tensor Fields
The Lagrangian formalism for tensor fields over differentiable manifolds with different (not only by sign) contravariant and covariant affine connections and a metric [(Ln, g)-spaces] is considered. The functional variation and the Lie variation of a Lagrangian density, depending on components of tensor fields (with finite rank) and their first and second covariant derivatives are established. ...
