Algebraic Simplex: Formulation

Algebraic Simplex Method - Formulation

The Simplex Formulation

To solve this model, the simplex method needs a system of equations instead of inequalities for the functional constraints. The demo, Interpretation of Slack Variables, describes how this system of equations is obtained by introducing nonnegative slack variables,

and

. The resulting equivalent form of the model is

The simplex method begins by focusing on equations (1) and (2) above.
