Golden Section Search Toolbox

This toolbox provides an interactive visualization of the Golden Section Search (GSS) optimization approach.

Details:

This toolbox is part of the optimization visualizing series that I developed during the optimization class at Georgia Tech. More details about these toolboxes and packages is presented in this blog post.

Have you ever heard about golden ratio and it's applications (in fact, appearance) in the nature, physical processes, architecture, art, etc.? The golden-section search algorithm is another application of this mysterious number. This toolbox is an implementation of this optimization approach and provide an step-by-step visualization of the optimization process. This toolbox can also serve as an effective educational demo in the optimization courses.

Sample run

Install the toolbox on MATLAB

• Run "Golden Section Search.mltbx" in MATLAB and complete the installation
• Run gss in MATLAB command window
• Enjoy! (The app will be run with a pre-set values as an example)

Notes

• The source codes are also available in src folder.
• Please note that the GUI is built and tested in Windows; there might be some visual differences in macOS (for instance, the test may appear smaller)
• Please feel free to contact me if there is any problem or questions.
