A more general method known as Simplex Method is suitable for solving linear programming problems with a larger number of variables. The method through an.
The best-known and most widely used procedure for solving linear programming problems is the Simplex Algorithm (or Simplex Method) which was.

9.3 THE SIMPLEX METHOD: MAXIMIZATION. For linear programming problems involving two variables the graphical solution method introduced in Section 9.2 is
The simplex algorithm is an iterative algorithm to solve linear programs of the form (2) by walking from vertex to vertex along the edges of this polytope until arriving at a vertex which maximizes the objective function cx To illustrate the simplex method for concreteness we will consider the following linear program maximize 2x 1 + 3x 2
Simplex method • invented in 1947 (George Dantzig) • usually developed for LPs in standard form (‘primal’ simplex method) • we will outline the ‘dual’ simplex method (for inequality form LP) one iteration: move from an extreme point to an adjacent extreme point with lower cost questions 1 how are extreme points characterized
The simplex method is to proceed from one BFS (a corner point of the feasible region) to an adjacent or neighboring one by choosing exactly one of non-basic variables to increase its value in such a way as to continuously improve the value of the objective function We now prove ii) in the next slide aText p 21 15
Chapter 6Linear Programming: The Simplex Method We will now consider LP (Linear Programming) problems that involve more than 2 decision variables We will learn an algorithm called the simplex method which will allow us to solve these kind of problems Maximization Problem in Standard Form

The first step involved in the simplex method is to construct an auxiliary problem by introducing certain variables known as artificial variables into the standard form of the linear programming problem.
The Simplex method on the other hand continues to be competitive after almost 7 decades since it was first articulated by George Dantzig. Sure, it has a worst-case exponential complexity, but in practice it performs very well on many LPs. There is another class of algorithms for solving LPs called Interior Point
In the graphical method, the solution space is delineated by the halfby the halfspaces representing the spaces representing the onstraints, and in the simplex method the solutiononstraints, and in the simplex method the solution space is represented by space is represented by mmm simultaneous linear equations and
nonnegative variables.
The Simplex method is a one-way communication technique. Only one client (either the sender or receiver is active at a time). If a sender transmits, the receiver can only accept. Radio and Television transmission are the examples of simplex mode.
