MATLAB: How should I write the fitness function for a function(fun1) with double summation

Question

M = 8;

N = 5;

5≤x(1) ≤ 20

7≤x(2) ≤ 15

0≤x(3) ≤ 1

5≤x(4) ≤ 20

7≤x(5) ≤ 15

0≤x(6) ≤ 1

fun1 =

Answer 1

This seems straightforward (at least to me, unless there is more to this than is posted):

fcn = @(x,M,N) M*(x(1)/(x(2)+5)-x(3)) + N*(x(4)/(x(5)+5)-x(6));

then with ‘M’ and ‘N’ defined in the workspace, call it as:

ftns = @(x) fcn(x,M,N)

If you are using the ga (genetic algorithm) function, it is straightforward to constrain the parameters. See the documentation for that.
