说明：  采用牛顿法和阻尼牛顿法求解4维无约束极值问题,利用牛顿法确定的搜索方向S，再采用黄金分割法确定最佳步长，所得结果为全局极值点。(Newton method and damped Newton method are used to solve the 4-D unconstrained extremum problem. The search direction s determined by Newton method is used, and the optimal step length is determined by golden section method. The result is the global extremum point.)
