![]() This version does NOT implement the Revised Simplex Method and it uses neither any implicit inverse update schemes nor any sophisticated entering variable selection scheme. These files should perform well on 'small' problems where A is m x n with m,n < 100. The file UNBOUND.MAT contains an LP that has an unbounded, feasible ray along which the objective value will tend to infinity. The file PHIDEGEN.MAT contains an LP for which phase I produces a degenerate solution, but for which the original LP has an optimal solution. ![]() The file INFEAS.MAT contains an LP that is infeasible. ![]() Klee for which the m x 2m system of constraints requires 2^m - 1 iterations (half during phase I and half during phase II). These particular LP's are of a type attributed to V. Then the below code will be helpful to you. The files OPT1.MAT, OPT2.MAT and OPT3.MAT contain matrices for LP's possessing an optimal solution. Expert Answer We hope that you are having the general logic of revised simplex method and 2phase method. In addition, there are a number of mat-files containing examples. ![]() The three files LINPROG.DOC, PHASEI.DOC and PHASEII.DOC are fully documented versions of the m-files LINPROG.M, PHASEI.M and PHASEII.DOC are fully documented versions of the m-files LINPROG.M, PHASEI.M and PHASEII.M. This directory contains a suite of files for performing the standard two phase simplex method on linear programming problems.
