>>>     p = so.Parameter(name='p')
>>>     x.set_value(2.5)
>>>     def func1():
>>>         p.set_value(1)
>>>     def func2():
>>>         p.set_value(2)
>>>     def func3():
>>>         p.set_value(3)
>>>     def func4():
>>>         p.set_value(0)
>>>     switch_conditions(x < 1, func1, x < 2, func2, x < 3, func3, func4)
>>> print(to.optmodel(w))
