Web24 Feb 2013 · x + y ≥ 2. x, y ≥ 0. The feasible region is as follows. In this case, you can see we can move as much as we want the objective function in the growing sense of x and y coordinates without leaving the feasible region. Therefore, objective function can grow too into feasible region, so we are in an unbounded solution case for this problem.
