(This article originally appeared in Management Science, January 1981, Volume 27, Number 1, pp. 1-18, published by The Institute of Management Sciences.) One of the most computationally useful ideas of the 1970s is the observation that many hard integer programming problems can be viewed as easy problems complicated by a relatively small set of side constraints. Dualizing the side constraints produces a Lagrangian problem that is easy to solve and whose optimal value is a lower bound (for…

An integer programming model is established and a heuristic algorithm based on Lagrangian relaxation to solve a new class of assignment problem arising from the slab production in steel industry.

A View of Lagrangian Relaxation and Its Applications

The core of the chapter is the presentation of several examples of Lagrangian heuristic algorithms in areas such as assignment problems, network optimization, wireless sensor networks and machine learning.
