Simplex Method Calculator with Steps
How Simplex Method Calculator Works
Enter the LP Problem
Type the objective function coefficients and every constraint row with its right-hand-side value.
Choose Maximize or Minimize
Pick your optimization goal. The tool builds the initial tableau with slack variables automatically.
Run the Pivot Iterations
The calculator identifies pivot column by Cj-Zj, computes ratios, performs elementary row operations until optimal.
Read the Optimal Solution
Final tableau displays optimal variable values, Zj row, and the maximum/minimum objective value.
Sample Simplex Tableau Output
Example tableau iteration for a 2-variable maximization problem
| Basis | x1 | x2 | s1 | s2 | RHS | Cj-Zj |
|---|---|---|---|---|---|---|
| x1 | 14 | 0 | 0 | 1 | 14 | 0 |
| x2 | 7 | 1 | 0 | 0 | 7 | 5 |
| Zj | 35 | 5 | 0 | 0 | 35 |
Frequently Asked Questions
How to solve simplex method on calculator?
Input your LP variables, coefficients, and constraints. The simplex calculator runs through each tableau iteration and shows you the step-by-step pivot process until reaching the optimal solution.
What does a step-by-step simplex calculator show?
It displays the initial tableau with slack variables, identifies the pivot column and row, performs elementary row operations, and shows the updated tableau for every iteration until the optimal solution is found.
