Click For Summary
The Jordan exchange is a technique used in the Simplex Method to facilitate the pivot operation during optimization. It involves selecting a pivot element from the tableau that will help maintain the feasibility of the solution while improving the objective function. The choice of the pivot element is crucial, as it determines the direction of the optimization process. Typically, the pivot is chosen based on the most negative coefficient in the objective row for maximization problems. Understanding the role of Jordan exchange enhances the efficiency and effectiveness of the Simplex Method in linear programming.
