Calculator Inputs

This tool solves two-variable linear programs using the graphical corner-point method.

Non-negativity is applied automatically: x ≥ 0, y ≥ 0.

Constraints

Constraint 1
Constraint 2
Constraint 3
Constraint 4
Constraint 5
Constraint 6

Formula Used

Objective function: Z = c1x + c2y

Constraints: aix + biy ≤, ≥, or = di

Non-negativity: x ≥ 0 and y ≥ 0

Optimization rule: Evaluate Z at every feasible corner point, then choose the largest value for maximization or the smallest value for minimization.

This page uses the graphical corner-point method for two decision variables. Constraint lines are intersected in pairs, feasible points are filtered, and the objective function is tested at each feasible corner.

How to Use This Calculator

  1. Choose whether you want to maximize or minimize the objective value.
  2. Enter the objective coefficients for x and y.
  3. Fill in each constraint with coefficients, relation type, and right-side value.
  4. Set the decimal precision and graph padding if needed.
  5. Click Optimize Now to generate the result above the form.
  6. Review the feasible corner points, objective values, and chart.
  7. Use the CSV or PDF buttons to export the report.

Frequently Asked Questions

1. What does this calculator solve?

It solves two-variable linear programming problems with a linear objective function and linear constraints. It identifies feasible corner points, evaluates the objective value, and shows the best bounded solution when one exists.

2. Does it support maximization and minimization?

Yes. You can choose either mode. The calculator tests the objective value at each feasible corner point and returns the largest value for maximization or the smallest value for minimization.

3. Why are only two variables used?

This page uses a graphical corner-point approach, which is most practical for two decision variables. More variables usually require simplex or other matrix-based optimization methods.

4. What happens if no solution exists?

If the constraints conflict and no point satisfies all of them together, the result is marked infeasible. In that case, no feasible region and no valid optimum can be reported.

5. What does an unbounded result mean?

An unbounded result means the feasible region lets the objective improve forever in the chosen direction. The calculator reports that no finite maximum or minimum is available.

6. Why are corner points important?

For linear programming with a bounded feasible region, the optimal value occurs at a corner point. That property makes corner-point testing a reliable method for two-variable models.

7. Can I export my results?

Yes. After solving, you can download a CSV summary or generate a PDF report containing the status, objective details, feasible points, and optimal solution information.

8. What units should I enter?

Use any consistent units that fit your model. For example, x and y may represent labor hours, product quantities, or shipping loads, as long as every coefficient matches the same scale.
