Set heuristic emphasis to aggressive in pyscipopt

I would like to make scip use heuristics more aggressively via pyscipopt. There is

model.setRealParam('limits/gap', 0.01)

and I am looking for something similar. To look at all parameters it is suggested to use

model.writeParams('default.set', onlychanged=False)

but in the resulting default.set a search for "emphasis" only leads to some precedence options. (How) Can I specify aggressive heuristics in pyscipopt? Thanks!

Solution

  • You have the option to use:

    model.setHeuristics(SCIP_PARAMSETTING.AGGRESSIVE)

    The emphasis settings in SCIP are not just one setting, but each emphasis setting is a collection of individual parameters.
