代码描述

中文说明:一个变量的优化目标函数值与黄金分割法。黄金分割搜索求极值的方法(最小或最大)的一个严格单峰functionby依次缩小值内的极值是已知存在的范围。该技术源于它的名字来自事实,该算法保持点的距离的三元组形成一个黄金比例的函数值。该算法是斐波那契搜索限制(也见下文)为大量的功能评价。Fibonacci搜索和黄金分割搜索发现了基弗(1953)。(参见Avriel和怀尔德(1966))。


English Description:

One variable optimation the objecive function value with golden section method. The golden section search is a technique for finding the extremum (minimum or maximum) of a strictly unimodal functionby successively narrowing the range of values inside which the extremum is known to exist. The technique derives its name from the fact that the algorithm maintains the function values for triples of points whose distances form a golden ratio. The algorithm is the limit of Fibonacci search (also described below) for a large number of function evaluations. Fibonacci search and Golden section search were discovered by Kiefer (1953). (see also Avriel and Wilde (1966)).
