Abstract
A method for providing a convex piecewise-linear expression which can be used for a system having thousands of variables is described. Data regions are defined and planes fitted to the data with the limitation that no plane exceeds the data by more than a set tolerance. A set of planes is formed and planes are added to the set one at a time found on the amount error reduction. After a plane is added to the set refitting occurs and another plane is selected for inclusion into the set.
