depth-first to breadth-first?

[moati]

Hi,

As far as I know, Gurobi does not have depth-first and breadth-first strategies but if I believe that the optimizer is stuck at a certain part of the search tree and I would like to change that part which parameter should I modify?

Thanks,

Hi Moati,

I think that the best parameter to change would be

Best,

Thanks for the suggestion. I presume in this case I should put MIPFocus to 1 to put more effort into finding better feasible solutions.

Is there any other way to add some randomness to the optimizer?

Thanks,

You could change the seed

will this have an effect in the middle of the optimization or this has to be a completely different run?

It would have to be a different run
