In MATLAB, we provide a simple instance to get started with the execution of Simplex algorithm:

Sample Code

A basic execution of Simplex algorithm by using MATLAB platform is offered below:  

function [optimalSolution, optimalValue] = simplex(c, A, b)

% Function to perform the Simplex algorithm for linear programming

% min c’x

% subject to Ax = b, x >= 0

[m, n] = size(A);

% Initialize tableau

tableau = [A, eye(m), b];

tableau = [tableau; -c’, zeros(1, m), 0];

% While there are negative entries in the bottom row

while any(tableau(end, 1:end-1) < 0)

% Find pivot column (most negative entry in the bottom row)

[~, pivotCol] = min(tableau(end, 1:end-1));

% Check for unboundedness

if all(tableau(1:end-1, pivotCol) <= 0)

error(‘The problem is unbounded.’);

end

% Find pivot row using minimum ratio test

ratios = tableau(1:end-1, end) ./ tableau(1:end-1, pivotCol);

ratios(ratios <= 0) = inf;

[~, pivotRow] = min(ratios);

% Perform pivot operation

pivotElement = tableau(pivotRow, pivotCol);

tableau(pivotRow, 🙂 = tableau(pivotRow, 🙂 / pivotElement;

for i = 1:size(tableau, 1)

if i ~= pivotRow

tableau(i, 🙂 = tableau(i, 🙂 – tableau(i, pivotCol) * tableau(pivotRow, :);

end

end

end

% Extract optimal solution and value

optimalSolution = zeros(n, 1);

basicVars = find(tableau(1:end-1, n+1:n+m) == 1);

optimalSolution(basicVars) = tableau(1:m, end);

optimalValue = -tableau(end, end);

end

% Example usage:

c = [-3; -2]; % Coefficients of the objective function

A = [1, 2; 1, 1; 0, 1]; % Coefficients of the constraints

b = [6; 4; 2]; % Right-hand side of the constraints

[optimalSolution, optimalValue] = simplex(c, A, b);

disp(‘Optimal Solution:’);

disp(optimalSolution);

disp(‘Optimal Value:’);

disp(optimalValue);

Description

1. Set up:

• c: It indicates the factors of the objective function.
• A: This A represents the factors of constraints.
• b: Here, b reflects the right-hand side of the constraints.

2. Tableau Design:

• Encompassing the b vector, identity matrix for slack variables and coefficients matrix A, we need to design the preliminary simplex tableau.
• Row of objective function must be included in the tableau.

3. Simplex Algorithm Loop:

• The outcome is not possibly best, as it contains negative entries in the row of objective function.
• Pivot column which indicates the highest negative entries in the bottom row ought to be detected.
• Unboundedness should be verified. (The problem is immeasurable, if an overall entry in the pivot column is non-positive).
• To detect the pivot row, we have to conduct a minimum ratio test.
• For upgrading the tableau, the pivot function must be carried out.

4. Retrieve best output and Value:

• From the tableau, the best solution and its measure is required to be retrieved, once after the tableau is enhanced.

Instance of Application

Along with a problem instance, we provide a sample application as a conclusion on how to implement the simplex function:

• Objective function coefficients c = [-3; -2]
• Constraint coefficients A = [1, 2; 1, 1; 0, 1]
• Right-hand side b = [6; 4; 2]

The best outcome and the best measure of the objective function can be exhibited in the findings.

For academic projects, this execution is highly suitable and it manages only the simple cases. We can deploy MATLAB’s built-in functions like linprog for addressing extensive linear programming tasks or complicated issues.
