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 using graphing calculator?
On a TI-84, store the tableau in a matrix using MATRIX > EDIT, then use row operations via MATRIX > MATH (rowSwap, *row, *row+). Alternatively, use a dedicated simplex app available for TI calculators.
Can we calculate simplex method pivot operation by Casio?
Casio scientific calculators have no built-in simplex function. However, you can manually perform matrix row operations using Casio's Matrix mode to carry out each pivot step.
