  You can define x as a semi-continuous variable. A semi-continuous variable has the property that it takes a value of 0 or a value between the specified lower and upper bounds. With the Python API, you can define your x variable as follows:

  x = model.addVar( lb = threshold, vtype = "S", name ="x")
