平分法求极值：取具有极小点点单峰函数的搜索区间的中点，计算目标函数在该点的导数来判断舍去的区间。-Equal distribution of the Method of Extremum

网格二分法求函数极值问题，通过不断的分格逼近，取得近似值-Grid dichotomy demand function extremum problem, through the constant sub-grid approximation to obtain approximate

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.
