There exist many Lagrangean methods for solving linear integer problems from which one of the most used is the Lagrangean relaxation. This paper presents a survey of such methods. The different Lagrangean lower bounds are compared and it is attempted to show how a linear integer problem may be analysed in order to choose a good Lagrangean method.
