  10. MILP LB TIMEOUT

MILP LB TIMEOUT

Name:MILP_LB_TIMEOUT
Type:double
Default Value:5
Range:[1–1.79e308]

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.
