Abstract

Abstract The simplex method is widely used to solve linear programming problems in diverse application areas. It is used as a stand‐alone solver and also as the computational engine of the solution of other optimization problems. The emerging problems tend to be large to very large. Practical solution of such problems requires sophisticated implementation of the simplex method. This article gives an account of the most important developments that have enabled the simplex method to become a reliable, efficient, and flexible solver.
