The cutting plane method is one of the algorithms included in the exact method. This algorithm works by reducing the solution area so that it becomes narrower. As a result, the feasible solutions that will be investigated become less and less. This is because the cutting plane method works based on the optimal linear programming solution of relaxation solved by the simplex method.
