Hi,
I am solving a huge MIP (4446310 integer variables). I set the relative gap to 0% from CPLEX MIP settings. After 69532.16 sec (19.3 hours), the model stops running and the solver status says 'Terminated by solver' while the gap is 0.14%. Why does this happen? What are the possible causes? Thank you.
Best regards,
Wanie Saidi
