python - How to handle Abs constraints in Gurobi? - Stack Overflow
I have a abs constraint in Gurobi. I have look into the manual of official guide. It provides two ways to add abs constraints. # x5 = abs(x1) model.addGenConstrAbs(x5, x1, "absconstr") # overloaded form model.addConstr(x5 == abs_(x1), name="absconstr")

absolute value constraint on vectorised variable setting – Gurobi Help Center
December 4, 2020 - Unfortunately, MVar objects cannot currently be used with general constraints. The development team is aware of the limitation. For now, you can use MVar.tolist() (new in Gurobi 9.1) to obtain the list of Var objects associated with the matrix variable(s). These Var objects can be used with Model.addGenConstrAbs()/abs_().
