Improved particle swarm optimization (PSO) algorithm

This tool can be used for every type of optimization problem (minimization / maximization / fitting, single / multi objective).

Vistit the engimix.com platform to run online or download my engineering packages, including:

• Mathematical optimizer (e.g. multi-method and multi-objective optimizer based on the PSO (Particle Swarm Optimization) algorithm, GA (Gentic Algorithm) and GD (Gradient Descent) method);
• Electrical models (e.g. PMSM (Permanent Manget Synchronous Motor) control and modelling);
• Thermal models (e.g. heat pumpts, etc.);
• Etc.

You will find user-guides, documentation, demos and source code for each package.

Test cases

Two test cases are shown:

• TestCase01_SingleObjFunOpt: Experimental data fitting.
• TestCase02_MultiObjFunOpt

How to run

• Open the folder associated to one of the two test cases;
• Run "Fitting.m" or "Minimization.m" according to the test case you have choosen

How to modify it:

• Open the folder associated to one of the two test cases;
• Modify the script to calculate the objective function to be optimized in the "ObjFun_fun.m" file mantaining the input and output data formats;
• Modify the parameters in the main file ("Fitting.m" or "Minimization.m" according to the best case you have choosen)
• Run the main file ("Fitting.m" or "Minimization.m" according to the best case you have choosen)
