Fourth precision solution can be derived from two grid sets solution with a second precision central difference scheme by Richardson extrapolation. It reduces the amount of calculation. Uncertainty is determined from the discretization error analysis. A finer grid calculation is made to validate the extrapolation scheme.

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.

该算法依据最钝角原理略去部分约束得到一个规模较小的子问题，用原始单纯形算法解之；再添加所略去的约束恢复原问题，若此时全部约束条件均满足则已获得一个基本最优解，否则用对偶单纯形算法继续求解。
