Dear all
maximizing f(x) = x2 using genetic algorithm,
where x ranges from 0 to 31. Perform 4 iterations. i got his code form one site. code is
%program for Genetic algorithm to maximize the function f(x) =sin(x)
clear all;clc;%x ranges from 0 to 3.14
%five bits are enough to represent x in binary representation
n=input('Enter no. of population in each iteration');nit=input('Enter no. of iterations');%Generate the initial population
[oldchrom]=initbp(n,5);%The population in binary is converted to integer
FieldD=[5;0;3.14;0;0;1;1]for i=1:nitphen=bindecod(oldchrom,FieldD,3);% phen gives the integer value of the
%binary population
%obtain fitness value
FitnV=sin(phen);%apply roulette wheel selection
Nsel=4;newchrix=selrws(FitnV, Nsel);newchrom=oldchrom(newchrix,:);%Perform Crossover
crossoverrate=1;newchromc=recsp(newchrom,crossoverrate);%new population after crossover
%Perform mutation
vlub=0:31;mutationrate=0.001;newchromm=mutrandbin(newchromc,vlub,mutationrate);%new population
%after mutation
disp('For iteration');idisp('Population');oldchromdisp('X');phendisp('f(X)');FitnVoldchrom=newchromm;end
when i am ruining this it gave error
??? Undefined function or method 'initbp' for input arguments of type 'double'.Error in ==> bookcode at 9[oldchrom]=initbp(n,5);
please some one give me solution
Thank you.
