说明：  最优化方法实验设计，研究Broyden族拟Newton算法中fai(k)取值的优化问题,即对于不同的目标函数，考虑取何值时算法是最优的，重点考察的区间[-2 2]范围内的变化情况，算法的优劣程度由CPU运行时间决定。
(Optimization method, design of experiments to study the proposed Newton algorithm Broyden family fai (k) values of the optimization problem, namely, for different objective functions, given the value of taking what algorithm is optimal, focusing on inspection interval [-22] changes within the scope of the algorithm' s advantages and disadvantages of the decision level from the CPU running time.)
