Generation of all integer points for given sets of linear inequalities

Abstract

We propose to give a computationally feasible procedure for the generation of all the integer points satisfying a given set of inequalities. Five different systems of inequalities will be considered. In order to generate all of these integer points, one requires a particular set of integer points, called fundamental points, and a set of linearly independent vectors with integer components. The number of these fundamental points is given by a simple formula. We show how to generate the fundamental points and the required vectors. We give an application concerning the localization of the integer optimum of a linear objective function subject to constraints which geometrically define a cone or a parallelotope.
