Add a constraint to a model.
Note that this method also accepts a TempConstr as its first argument (with the constraint name as its second argument). This allows you to use operator overloading to create a variety of different constraint types. See TempConstr for more information.
sense: Sense for the new constraint (GRB.LESS_EQUAL, GRB.EQUAL, or GRB.GREATER_EQUAL).
name: Name for new constraint. Note that name will be stored as an ASCII string. Thus, a name like 'AB' will produce an error, because '' can not be represented as an ASCII character. Note also that names that contain spaces are strongly discouraged, because they can't be written to LP format files.
New constraint object.
model.addConstr(x + 2*y, GRB.EQUAL, 3*z, "c0") model.addConstr(x + y <= 2.0, "c1") model.addConstr(x*x + y*y <= 4.0, "qc0") model.addConstr(x + y + z == [1, 2], "rgc0") model.addConstr(z == and_(x, y, w), "gc0") model.addConstr(z == min_(x, y), "gc1") model.addConstr((w == 1) >> (x + y <= 1), "ic0")
