Some constraints are selected, and omitted according to the most-obtuse-angle principle. The smaller problem is solved with the simplex method. Then the omitted constraints are added to restore the original problem. If all the constraints are satisfied, then a basic optimal solution is reached. In the other case, the dual simplex method is used to obtain the basic optimal solution.
