Hi guys,
I trying to solve a small mip:
Max 2 x1 + x2 - 3 x3
subject to:
r1: 2 x1 + x2 >= 4
r2: 1 x1 + 4 x2 + 2 x3 = 5
r3: 3 x2 + x3 <= 7
x1 -> LB = 0
x2 -> LB = 0
x2 -> UB = 4
x3 -> UB = 5
I know it no have a optimal solution, but the
method model->secondaryStatus() returns 1 (1 linear relaxation not feasible
(or worse than cutoff) ).
However the problem is unbounded, i expected 7 (7 linear relaxation
unbounded).
Att.
