THE APPLICATION OF C++ PROGRAMMING IN THE SIMPLEX METHOD
Abstract
In
this paper, we first introduce the general linear programming problem and then
a mechanism to convert any general linear programming problem into the standard
form.
In

extreme point to an adjacent extreme point in the search for an optimal
solution. We first discuss the algebra of simplex method and then the simplex
method in tableau form. The aim of this paper is not only to understand the
mechanics of the tableau method, but also the theoretical foundation upon which
the mechanical operations are built.
Finally,
we solve the linear programming problem by using a computer program with C++
language.
