A sample problem can be as following:
(P)
Min z1=x
X <= y
(P')
Min z2=0
y <= b (b is a constant)
z1_min <= k (k is a constant)
where z1_min, is the optimal value of the objective function for the
problem (P). The decision variables in the problem (P') parameterize
the constraints in the problem (P).
