Simplex Algorithm Calculator

Simplex Algorithm Calculator is an online application on the simplex algorithm and two phase method.

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 "Delete Column"
3) Enter the matrix of constraints in the columns denoted by Ai. Note that you can resize the problem using the menu "Add Row", "Add Column", "Delete Row" and "Delete Column"
4) Click the sign foreach constraint of the problem,
5) Enter the constraints vector in the column denoted by B. Note that you can resize the problem using the menu "Add Row" and "Delete Row"

Run and Outputs


To begin the calculations click on one of these two actions:
    1) Step by Step Execution: This option will run the Simplex algorithm showing each iteration: A window opens showing how the algorithm pivoting matrix at each step, the solutions and some statistics, such as phase, number of steps of the simplex, the indexes on the base ... Within this option, select
         1a) for the calculation mode "Fraction Mode" or "numeric mode"
         1b) Next step: This option will Avanze a new step in the simplex algorithm
         1c) Back to Menu: Closes the current window and returns to the original with the simplex algorithm.
    2) Execute Simplex: This option will run the Simplex algorithm on the problem introduced in the previous steps:a window will be opened in seconds after this click with the final solution found and execution statistics.

Final comments


Simplex Algorithm Calculator comment that is not restricted from us about the extent of the problem and that the precise tolerance in the calculations is 16 decimal digits.
At the same time the maximum processing time for a linear programming problem is 20 second, after that time any execution on the simplex algorithm will stop if no solution is found.





Was useful? want add anything?

Very nice tool, is there a way to add a constant to the cost vector?
