Hello all, I would like to know whether it is possible to get approximate results using IBM optimization tools (CPLEX, ILOG CP etc).

The reason to search for such an option is that in my optimization problem, I have limited time to solve the problem.

Moreover, I would like to have some theoritical guarantees that how much far the approximate solution is from the optimal solution? What possibilities do I have using the exisiting tools?

Thanks in advance for taking out time for this question and hope to hear from you!
