Golden Section Search Algorithm Implementation in MATLAB
Golden Section Search Algorithm
Overview of the Algorithm
The Golden Section Search algorithm is an optimization technique used to find the extremum (maximum or minimum) of a unimodal function within a specified interval. It leverages the golden ratio to reduce the search interval step-by-step, ensuring efficient convergence.
Steps of the Algorithm
Initialize two points within the interval [a, b] using the golden ratio.
Evaluate the function at these two points.
Compare the function values and update the interval by removing the unnecessary part.
Repeat the process until the desired precision is reached.
Return the optimal point and function value.
MATLAB Implementation
Below is a sample MATLAB code to implement the Golden Section Search algorithm:
function [x_opt, f_opt] = golden_section_search(f, a, b, tol)
phi = (1 + sqrt(5)) / 2;
c = b - (b - a) / phi;
d = a + (b - a) / phi;
while abs(b - a) > tol
if f(c) < f xss=removed xss=removed xss=removed xss=removed xss=removed xss=removed>
This code defines a function golden_section_search that finds the optimal point within the interval [a, b] using Golden Section Search.
Advantages
Efficient for unimodal functions.
Simple to implement with minimal function evaluations.
Converges faster than other search methods for specific cases.

Matlab Implementation of Gradient-Based ICA Algorithm
一种基于梯度的ICA算法
本算法利用梯度优化方法来实现独立成分分析(ICA)。ICA是一种常用于信号分离的技术,而梯度优化可以有效地提升算法的收敛速度和性能。以下是该算法的主要步骤:
初始化:设定初始的权重矩阵和学习率。
梯度计算:通过计算梯度,更新权重矩阵以最大化独立性。
收敛判定:当权重矩阵变化小于预定阈值时,判定收敛,输出分离信号。
优化更新:利用梯度下降法持续优化结果,确保分离效果的最优化。
该算法能够有效处理盲源分离问题,且具有较强的实际应用价值。
