Calling Multiple Input Variable for Genetic Algorithm

Hi,

I am trying to call simple multiple input variable by GA while I face error, Would you please help me how to solve the issue,

The main function is :

function R = Final(a,b,k)

R=a(1)a(2)+b+k;

end

and tried to use GA for it as below:

clc, clear, close all

FitFcn= @(a,b,k)Final(a,b,k);

nvars=4;

[a,b,k,fval]= ga(@(a,b,k)FitFcn,nvars);

Please support me to know how to use GA for multi variable

Hi ,

I am trying to Optimise the Single Objective - Multi Variable Optimization problem involving 7 Variables with the help of Genetic Algorithm, but found errors in GA handling function. Could you please explain how to call function using GA Handler?

This is the correct code. Compare it with your code to see how to input a function handle to ga() properly.

clc, clear, close all
FitFcn= @(a,b,k)Final(a,b,k);
nvars=4;
[x,fval]= ga(@(x) FitFcn(x(1:2),x(3),x(4)),nvars);
a_solution = x(1:2);
b_solution = x(3);
k_solution = x(4);

function R = Final(a,b,k)
    R=a(1)*a(2)+b+k;
end
