Description: Powell优化算法是利用仪器测井理建立误差函数（非相关函数），借助Powell方向加速法求出非相关函数达到最小时的解，对于气，水两相流动，从预设的气，水流量初始值出发，沿不同的广向进行搜索，可求出气，水两相流动中可能最大产量。与目前常用的生产测井解释方法相比，文中提出的方法具有精度高，实用性强等优点，在测井曲线有缺陷时，仍有可能得到较好的结果。

Description: powell算法设计
鲍威尔法又称方向加速法，它由Powell于1964年提出，是利用共轭方向可以加快收敛速度的性质形成的一种搜索方法。该方法不需要对目标函数进行求导，当目标函数的导数不连续的时候也能应用，因此，鲍威尔算法是一种十分有效的直接搜索法。
Powell法可用于求解一般无约束优化问题，对于维数n<20的目标函数求优化问题，此法可获得较满意的结果。
不同于其他的直接法，Powell法有一套完整的理论体系，故其计算效率高于其他直接法。该方法使用一维搜索，而不是跳跃的探测步。同时，Powell法的搜索方向不一定为下降方向。(Powell method can be used to solve general unconstrained optimization problems. For the optimization of dimension n<20 objective function, this method can obtain satisfactory results.
Unlike other direct methods, the Powell method has a complete set of theoretical systems, so its computational efficiency is higher than other direct methods. The method uses one-dimensional search instead of jumping detection steps. At the same time, the search direction of the Powell method is not necessarily for the downward direction.)
