Check if the linear programming problem is a standard maximization problem in standard form, i. This solution is dictated by solving the Lagrangian formulation of the problem in (1). The graphical method is useful only for problems involving two decision variables and relatively few problem constraints. The process, instead of being represented as a single, straight-line process is represented as a circle. Login to add new listings. The table method doesn't work that well either. Use the simplex method to solve the problem.
