MIPFocus
MIP solver focus
Type: | int | |
---|---|---|
Default value: | 0 | |
Minimum value: | 0 | |
Maximum value: | 3 |
The MIPFocus
parameter allows you to modify your high-level
solution strategy, depending on your goals. By default, the Gurobi
MIP solver strikes a balance between finding new feasible solutions
and proving that the current solution is optimal. If you are more
interested in finding feasible solutions quickly, you can select
MIPFocus=1
. If you believe the solver is having no trouble
finding good quality solutions, and wish to focus more attention on
proving optimality, select MIPFocus=2
. If the best objective
bound is moving very slowly (or not at all), you may want to try
MIPFocus=3
to focus on the bound.
Note: Only affects mixed integer programming (MIP) models
