Comparison of Lagrangian Bounds for One Class of Generalized Assignment Problems
(Maik Nauka/interperiodica/springer, 2008-05-01)
Classical and modified Lagrangian bounds for the optimal value of optimization problems with a double decomposable structure are examined. For the class of generalized assignment problems, this property of constraints is ...

Improved Lagrangian bounds and heuristics for the generalized assignment problem
(2017-09-01)
Modified Lagrangian bounds are proposed for the generalized assignment problem. The approach is based on a double decomposable structure of the formulation. A family of greedy heuristics is considered to get Lagrangian ...
Augmented Lagrangian method with nonmonotone penalty parameters for constrained optimization

Valid inequalities for Lagrangian relaxation in an inventory location problem with stochastic capacity
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
We developed an efficient heuristic to solve a joint location-distribution-inventory model for a three layered supply chain. A firm must locate distribution centers to supply a commodity to spatially distributed retailers ...
A Relax-and-Cut algorithm for the set partitioning problem
(Pergamon-elsevier Science LtdOxfordInglaterra, 2008)
p-Cable Trench Problem with Covering
(2015)
We introduce the p-Cable Trench Problem with Covering. Secondary servers are located to provide service within a coverage radius (e.g., Wi-Fi antennas). Each secondary server must be connected to a primary server (a router), ...
Self-bound interacting QCD matter in compact stars
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
The quark gluon plasma (QGP) at zero temperature and high baryon number is a system that may be present inside compact stars. It is quite possible that this cold QGP shares some relevant features with the hot QGP observed ...
