About

This tool includes an implementation of five gradient-based algorithms, including

• (1) Steepest Descend Algorithm (SDA),
• (2) Conjugate Gradient Algorithm (CGA),
• (3) Newton's Method,
• (4) Davidson-Fletcher-Powell (DFP) Method,
• (5) Broyden–Fletcher–Goldfarb–Shanno (BFGS) Method,

for multivariate function optimization. For two variable functions, a user-friendly interactive interface is available which portrays the optimization procedure step-by-step. This toolbox can also serve as an educational tool to understand mainstream optimization techniques.
