PSO is used for problems involving global stochastic optimization of a continuous function called the objective function.

PSO can also be used for discrete optimization problems, but this behaviour is not implemented in the current version of this library. There's also an implementation in Go which can be found here. Just include pso. This is where the best position discovered will be stored, along with the minimum error stored in member error.

The value of the inertia weight w determines the balance between global and local search. Two different strategies are implemented:. A file demo. Type make for building the demo.

It is intended for swarm intelligence researchers, practitioners, and students who prefer a high-level declarative interface for implementing PSO in their problems.

PySwarms enables basic optimization with PSO and interaction with swarm optimizations. Check out more features below! This is the preferred method to install PySwarms, as it will always install the most recent stable release.

PySwarms provides a high-level implementation of various particle swarm optimization algorithms. Thus, it aims to be user-friendly and customizable. In addition, supporting modules can be used to help you in your optimization problem. This will run the optimizer for iterations, then returns the best cost and best position found by the swarm.

In addition, you can also access various histories by calling on properties of the class:. At the same time, you can also obtain the mean personal best and mean neighbor history for local best PSO implementations. Simply call optimizer. PySwarms implements a grid search and random search technique to find the best parameters for your optimizer.

Setting them up is easy. In this example, let's try using pyswarms. Here, we input a range, enclosed in tuples, to define the space in which the parameters will be found. Thus, 1,5 pertains to a range from 1 to 5. This then returns the best score found during optimization, and the hyperparameter options that enable it. It is also possible to plot optimizer performance for the sake of formatting.

The plotters module is built on top of matplotlibmaking it highly-customizable. We would also like to acknowledge all our contributorspast and present, for making this project successful!

Feb 27, Increased version number to 0. Aug 4, Feb 25, Updated 21 Mar This implementation of PSO is designed for solving a bounded non-linear paramter optimization problem, with an initial guess. It is fully vectorized. There are a variety of options that can be set by the user, but will be initialized to a default value if ommitted.

The output of the solver contains a full history of the optimization, which can be plotted using plotPsoHistory. Additionally, the user can define a plotting function to be called on each iteration.

The code supports both vectorized and non-vectorized objective function. If the objective function is vectorized, then the global best is updated synchronously, once per generation. If the objective function is not vectorized, then the optimization uses an asynchronous update, updating the global best after every particle update.

All fields are optional, with defaults:. Matthew Kelly Retrieved April 15, Without a doubt, one of the most robust and effective PSO's I've seen.
