With the restriction of water demand and supply, the objective function optimal value was calculated by sequential quadratic programming. 以需水量和可供水量为约束条件，采用序列二次规划法求解函数最优值。
Usually the method transforms the quadratic programming to the linear programming by the fact that any two norms are equivalent in the Euclid space. 许多文章提出用线性规划代替原有的二次规划来对支撑向量机进行训练，通常是利用欧式空间上两种范数的等价性将原来的二次规划转化为线性规划。
