How can I convert a multi objective optimization algorithm to a single objective one by using The weighting method ?

F =(f1 ,f2) my objective is maximised f1 et minimised f2 please help me !! thanks in advance

Answer 1

[Ugur Acar]

Assign weights to objective functions f1,f2) then optimize the weighted sum of f1 and f2

Answer 2

[Rohit Garud]

If J is your combined cost function and w1 and w2 are your weights then,

J = w1*(M-f1) + w2*(f2)

Here M is a large number which will always be greater than f1. As (M-f1) is minimized, f1 will be maximized.
