Deterministic unconstrained optimization method using Powell.
It's a deterministic iterative zero order algorithm that can be used to solve unconstrained optimization problem. It finds the relative minimum of a two variables function with a deterministic iterative zero order algorithm.

A new metaheuristic optimization algorithm, called Cuckoo Search (CS), is fully implemented, and the vectorized version is given here. This code demonstrates how CS works for unconstrained optimization, which can easily be extended to solve...
The Kalman filter is actually a feedback approach to minimize the estimation error in terms of sum of square. This approach can be applied to general nonlinear optimization. This function shows a way using the extended Kalman filter to solve some...
Demonstration of the gradient descent optimization algorithm with a fixed step size. This example was developed for use in teaching optimization in graduate engineering courses. This example demonstrates how the gradient descent method can be...
Ok, yes, my expectation was that when I saw this, before I downloaded it I expected it to be a student's homework assigment. In fact, this is a reasonably carefully crafted tool.
One serious issue is that this code requires you to...
Demonstration of finding the minimum of a noisy function using gradient-based optimization. This model was developed for use in teaching optimization in graduate engineering courses. It demonstrates one approach for attempting to find the...
Again, this SEEMS to be a reasonably crafted code. I wish it had better documentation, that explicitly said what the parameters did and what shape and size they should be. Some examples of use would be helpful. For example, this simple test case...

This upload contains a hybrid Particle Swarm Optimization algorithm for functions in the real space. An options file is also provided, which lets the user fully parameterize the process. The hybrid function used is the @fminsearch, which is...
This demo shows how to use MATLAB, Optimization Toolbox, and Genetic Algorithm and Direct Search Toolbox to optimize the design of a double wishbone suspension system.
Note: You will need to have the following products installed in...
GANSO is a programming library for global and nonsmooth, nonlinear optimization. Unlike local methods (e.g., quasi-Newton), global optimization methods aim at locating the absolute minimum of a function, not the nearest stationary point. GANSO...

This is a wrapper function to solve optimization problems (using FMINCON) of the form:
min w.r.t. X of CostFunc(X) = beta*(W_ls*F(X)) + (1 - beta)*(max(W_mm*F(X)))
subject to: A*X <= B, Aeq*X = Beq (linear... |
