Question 1:
(15 points)
(You do not need to be very rigorous for this question.)
In class we claimed the “Fundamental Theorem of LPs”: every linear program either has an optimal
solution, is unbounded, or is infeasible.
Consider the following linear program in
R

, whose objective function has not yet been speciﬁed.

(a):
Find an objective function (i.e., values of
a
and
b
) for which the linear program has a unique
optimal solution.
(b):
Find an objective function for which the linear program has inﬁnitely many optimal solutions.
