Rim Multiparametric Linear Programming
The rim multiparametric linear programming problem (RMPLP) is a parametric problem with a vector-parameter in both the right-hand side and objective function (i.e., in the "rim"). The RMPLP determines the region K* \subset E* such that the problem, maximize z(\lambda) = c<sup>T</sup>(\lambda)x, subject to Ax = b(\lambda), x \geqq 0, has a finite optimal solution for all \lambda \in K*. Let B<sub>i</sub> be an optimal basis to the given problem, and let R<sub>i</sub>*, be a region assigned to B<sub>i</sub> such that for all \lambda \in R<sub>i</sub>* the basis B<sub>i</sub> is optimal. The goal of the RMPLP problem is to cover K* by the R<sub>i</sub>* such that the various R<sub>i</sub>* do not overlap. The purpose of this paper is to present a solution method for finding all regions R<sub>i</sub>* that cover K* and do not overlap. This method is based upon an algorithm for a multiparametric problem described in an earlier paper by Gal and Nedoma.
