The online software will adapt the entered values to the standard form of the simplex algorithm and create the first tableau. Depending on the sign of the constraints, the normal simplex algorithm or the two-phase method is used. We can see step by step the iterations and tableaus of the simplex method calculator.

The Simplex Method The Simplex Method. The simplex method is an algebraic algorithm for solving linear maximization problems. Beginning at the origin, this algorithm moves from one vertex of the feasible region to an adjacent vertex in such a way that the value of the objective function either increases or stays the same; it never decreases.
