How to activate (or inactivate) cuts in Gurobi, with python? And where do I find a documentation of these cuts?

Question

I'm trying to adapt a model, using python, and trying to improve it by inactivate and activate some heuristics of B&C. For that, I'm looking for some help with how to manage parameters for cut heuristics and what types do I have in Gurobi.

Generally you can influence cuts and heuristics by setting parameters. There is an extensive list of parameters in the documentation. For example, to disable cut generation and heuristics for a given model you can do

import gurobipy as gp
m = gp.Model()
m.setParam(GRB.Param.cuts, 0)
m.setParam(GRB.Param.heuristics, 0.0)
