对一个三次函数寻找最优解（最小值），分别使用全局搜索法、二分法、黄金分割法和斐波那契法共四种方法寻优。函数可在程序中自行指定，有gui界面。(A cubic function to find the optimal solution (minimum), respectively, using a global search method, dichotomy, golden section and Fibonacci optimization method a total of four methods. Function can be specified in the program itself, there are gui interface.)
