Frequently Asked Questions

Find Quick Answers

What is the simplex method?

The simplex method is an algorithm for solving linear programming problems. It iteratively moves from one vertex of the feasible region to another, improving the objective function value until an optimal solution is found.

What types of problems can this calculator solve?

This calculator solves standard form linear programming problems with linear objective functions and linear constraints. It handles both maximization and minimization problems with ≤ constraints.

Does the calculator show intermediate steps?

Yes, the calculator displays all simplex tableaus showing each iteration of the algorithm, including the pivot operations and variable changes.

What if my problem has no feasible solution?

The calculator will detect infeasible problems and display an appropriate error message indicating that no feasible solution exists.

Is there a limit on the number of variables or constraints?

For performance reasons, the calculator is optimized for problems with up to 10 variables and 10 constraints, though it can handle larger problems depending on browser capabilities.
