Question
In this problem, we use weak duality to prove Lemma 3.
a Show that Lemma 3 is equivalent to the following:
If the dual is feasible, then the primal is bounded. (Hint:
Do you remember, from plane geometry, what the contrapositive is?)
b Use weak duality to show the validity of the form of
Lemma 3 given in part (a). (Hint: If the dual is feasible,
then there must be a dual feasible point having a
w-value of, say, wo. Now use weak duality to show that
the primal is bounded.)
