How to use objective function in linear programming ?

Hi all.

I have problem used objective function.

I want to apply " f(objective function) = 3x(1) + 4x(2) + 30 "

But In document in linear programming, f = [3 4]

In here, constant can not be used.

How to solve this problem?

Answer 1

[Torsten]

If you minimize 3*x1+4*x2, you automatically minimize 3*x1+4*x2+30.

So a constant in the objective function can be ignored in optimization problems.

Best wishes

Torsten.

To expand on Torsten's answer, once you find the point that minimizes 3x(1) + 4x(2), you can evaluate the objective function with or without the added 30.
