Example Analysis of PSOt Toolbox

This article shows you a sample analysis of the PSOt toolkit, concise and easy to understand, definitely will make your eyes shine, through the detailed introduction of this article I hope you can gain something.

Function optimization algorithm based on particle swarm toolbox to clear environment clearclc

Parameter initialization x_range=[-50,50]; % parameter x variation range y_range=[-50,50]; % parameter y variation range = [x_range;y_range]; % parameter variation range (composition matrix)Max_V = 0.2*(range(:,2)-range(:,1)); % maximum speed takes 10%~20%n=2; % dimension of the function to be optimized, in this example, there are only x and y arguments, so it is 2

PSOparams= [25 2000 24 2 0.9 0.4 1500 1e-25 250 NaN 0 0]; particle swarm optimization pso_Trelea_vectorized ('Rosenbrock ', n,Max_V,range,0,PSOparams) % invoke PSO core module function [out]=Rosenbrock(in)% optimization function x0=in(:,1:end-1);x1=in(:,2:end);

out = sum( (100*(x1-x0.^ 2).^ 2 + (x0-1).^ 2) , 2);
