Linear Programming and Minimization of Cost-Graphical Method: Linear programming graphical method can be applied to minimization problems in the same manner as illustrated on maximization example page. An example can help us explain the procedure of minimizing cost using linear programming graphical method. Example:
Linear Programming of Graphical Method
The graphical method is limited to Linear Programming problems involving two decision variables and a limited number of constraints due to the difficulty of graphing and evaluating more than two decision variables.
