[Cbc] Presolved Model Optimal - Message

[Nelson Mesquita Fernandes]

Hello all,

What does the following message means when running CBC optimizer on Widows?

“Presolve model was optimal, full model needs cleaning up”

CBC is taking 80 minutes to find the optimal solution, and the presolve model only takes a few seconds. Looking at this message, I was wondering if I could use the presolved solution, and avoid waiting more than one hour for the optimal solution.

Thanks,
Nelson
