<br>
<br>
I am running CBC by using ORtools to solve a MIP model of a
location problem.
<br>
The model is exported in LP format attached in this mail.
<br>
CBC gives a feasible solution and all values of decision
variables and objective function are 0. But this
<br>
solution violate many constraints. And I checked by running Cplex
the same
<br>
model (if I code correctly), and the optimal solution value are
not 0.
<br>
Could you tell me if the constraint format is OK or what is
reason of this problem.
<br>
<br>
Thanks and regards,
<br>
<br>
Xin
