genetic_al.m

一个遗传算法编的程序,大家看看吧.有人说不能用,但我用的很好.

function [chronom, Fval] =  genetic_al(hide)
% This is an auto generated M file to do optimization with the Genetic Algorithm and 
% Direct Search Toolbox. Use GAOPTIMSET for default GA options structure.

%%Fitness function
fitnessFunction = @fitness;
%%Number of Variables
nvars = 7*hide + 1;
%Start with default options
options = gaoptimset;
%%Modify some parameters
options = gaoptimset(options, 'PopInitRange', [-10; 10]);
options = gaoptimset(options, 'PopulationSize', 40);
options = gaoptimset(options, 'EliteCount', 1 );
options = gaoptimset(options, 'CrossoverFraction', 0.7);
options = gaoptimset(options, 'Generations', 200);
options = gaoptimset(options, 'FitnessLimit', 0.01);
options = gaoptimset(options, 'StallGenLimit', 10);
options = gaoptimset(options, 'StallTimeLimit', 400);
options = gaoptimset(options, 'CrossoverFcn', {@crossoverintermediate 1});
options = gaoptimset(options, 'MutationFcn', {@mutationgaussian 0.5 0.75});
options = gaoptimset(options, 'Display', 'off');
options = gaoptimset(options, 'PlotFcns', {@gaplotbestf});
%%Run GA
[chronom, Fval] = ga(fitnessFunction,nvars,[],[],[],[],[],[],[],options);
