日常生活生产中有大量求极值的问题，一般计算机实现用穷举法或牛顿迭代法，但其计算量非常大。使用单纯形法可根据单纯形各个顶点的目标函数值，加以比较，丢掉其中最坏的点，代之以新点，。-Daily production of a large number of extremum problems, general computer implemented by the exhaustive method or Newton' s iterative method, but its calculation is very large. Simplex method using the simplex according to the objective function value of each vertex, to be compared to losing one of the worst point, replace them with new points.
