Same relaxed solution every time
AnsweredHello guys,
not sure if this is the right place to ask something like this but maybe I found people which like solving other person problem xD.
I'm doing an exercise for school and I'm having problem finding the max and min value that tau[2] can have to keep the relaxed problem optimal base the same.
I noticed that for every value I assign to tau[2] I get always the same solution of the relaxed.
Here's my code (I also made a branch called Debug which should print the relaxed optimal solution)
My question is: Am I missing something about Gurobi library or is this just some theory lack?

Hi,
I am not sure that I fully understand your question. You can query Gurobi sensitivity information on a Gurobi variable via the attributes below:
 SALBLow and SALBUp: smallest and largest lower bound value at which the current optimal basis remains optimal.
 SAUBLow and SAUBUp: smallest and largest upper bound value at which the current optimal basis remains optimal.
Best regards,
Maliheh
