Add distributed operations to minimize ``loss`` by updating ``parameter_list``.
Args:
loss (Variable): A ``Variable`` containing the value to minimize.

initializing parameters in ``parameter_list``. The default value
is None, at this time :ref:`api_fluid_default_startup_program` will be used.
parameter_list (Iterable, optional): Iterable of ``Variable`` or ``Variable.name`` to update
to minimize ``loss``. The default value is None, at this time all parameters
will be updated.
no_grad_set (set, optional): Set of ``Variable`` or ``Variable.name`` that don't need
to be updated. The default value is None.
Returns:
tuple: tuple (optimize_ops, params_grads), A list of operators appended
by minimize and a list of (param, grad) variable pairs, param is
``Parameter``, grad is the gradient value corresponding to the parameter.
The returned tuple can be passed to ``fetch_list`` in ``Executor.run()`` to
indicate program pruning. If so, the program will be pruned by ``feed`` and
``fetch_list`` before run, see details in ``Executor``.
