Hello!

I am very new at ILOG CPLEX and OPL, I am doing a project that needs to get the optimized solution plus number of solutions.

It generates the number of solutions but runs forever and therefore will not generate the optimal solution. what could be causing this (running infinitely)?

Thank you.

Hi

Proving optimality can take a very long time using CP for the whole search tree must be traversed. have you try to put a limit in your model. You can do it by adding a parameter files to your run configuration and set a limit in the CP solver tab.

Hope that helps

I put a cp time limit, the problem is with the time limit, it does not generate the optimal solution.
