Inputs Simply enter your linear programming problem as follows 1) Select if the problem is maximization or minimization 2) Enter the cost vector in the space provided, ie in boxes labeled with the Ci. Note that you can add dimensions to this vector with the menu "Add Column" or delete the Linear Programming: It is a method used to find the maximum or minimum value for linear objective function. It is a special case of mathematical programming. Simplex Method: It is one of the solution method used in linear programming problems that involves two variables or a large number of constraint. The solution for constraints equation with nonzero variables is called as basic variables. The Simplex algorithm is a popular method for numerical solution of the linear programming problem. The algorithm solves a problem accurately within finitely many steps, ascertains its insolubility or a lack of bounds. It was created by the American mathematician George Dantzig in 1947. The The Simplex Method Described Tableau Format of the Simplex Method A useful tabular form displaying all the quantities of interest is given in figure 1. Such a format is called a tableau. A new tableau is constructed at each iteration i.e. each time a new column is introduced into the basis. m 1,1 m 1,2 m 1,3 m 1, p m 1, p 1 m 1, n m 1, n 1 Before the simplex algorithm can be used to solve a linear program, the problem must be written in standard form. a. Constraints of type (Q) : for each constraint E of this type, we add a slack variable A Ü, such that A Ü is nonnegative.

In the above eg x4 and x3 forms a 2×2 identity matrix. CB : Its the coefficients of the basic variables in the objective function. The objective functions doesn’t contain x4 and x3, so these are 0. XB : The number of resources or we can say the RHS of the constraints. The Simplex Method: Initialization • Let Abe an m×n matrix with rank(A) = rank(A,b) = m, bbe a column m-vector, xbe a column n-vector, and cT be a row n-vector, and consider the linear program z = max cTx s.t.
