When I use GA app, how to put the constraints with absolute value

Now I using ga app.

I want to put the constraints in ga app.

That constraints is below.

I can put the first constraint(g1), but my problem is second constraint(g2).

The second constraint(g2) have absolute value, how to apply it?

Hi,

You can use the "abs" function for handling absolute values in the second constraint. Here is a sample code for the same:

g1 = sum(L(1:Ns) .* Ki(1:Ns)) / L - r1;
g2 = sum(abs(K(1:Ns-1) - K(2:Ns))) - r2;

You can read more about the "abs" function here:

Hope this helps!
