拟牛顿法（变尺度法）DFP算法，求解无约束极值问题。

在没有约束条件之下，一维的最优极值求解，这求解极值问题上很有用-In the absence of constraint conditions, one-dimensional optimal extreme solution, it is useful to solve the issue of extreme

模式搜索法，主要用于解决无约束多维极值问题。例如：飞机的精确定位。-Pattern search method, mainly used for to solve unconstrained multi-dimensional extremal problem. For example: the precise positioning of the aircraft.
