This option sets the timeout (in real-time seconds) for the MIP solver that it is used to solve MILP lower bounding problems at every node of the branch-and-bound tree. Giving the MIP solver more time means that the lower bound per node can be superior, at the expense of computing time.
Increase the timeout if:
- Your MIP relaxation starts clustering when it gets close to the global solution
Decrease the timeout if:
- A lot of time is spent solving MIP problems but you don’t see the bounds improving even after a lot of nodes have been explored.
