Solution to unbounded problems
AnsweredIf gurobi detects the problem is unbounded, e.g. unbounded LP, what solution will be returned?
For example,
\[\begin{align}\min \alpha \\ s.t. x \ge 0 \end{align} \]
what is the value of \(x\)?
0

If any feasible point has been determined by Gurobi before the problem is declared unbounded, then you can access this arbitrary feasible point via the X attribute. Note that it is possible that Gurobi finds a model to be unbounded before even finding a single feasible point. Then, no solution is available.
You should always check the SolCount attribute before trying to access feasible solutions.
if model.SolCount > 0:
# do something with the solution(s)Best regards,
