Abstract

We investigate the problem of finding the initial basic feasible solution in the simplex algorithm. Two modifications of the two-phase simplex method are presented. Implementations of the two-phase simplex method and its modifications in the programming package MATHEMATICA and the programming language Visual Basic are written. We report computational results on numerical examples from the Netlib test set.
