A Two-Phase Method for the Simplex Tableau
Preview not available

Abstract

A version of a two-phase simplex technique is given for manually solving those linear-programming problems in which artificial vectors are introduced and subsequently driven out. The first phase of the method determines feasibility, provided it exists; the second phase, which follows, searches for optimality.
