.. py:class:: AppendAction(song)

   .. py:method:: __repr__()

      Return repr(self).


   .. py:method:: apply(state)



.. py:class:: RemoveAction(index)

   .. py:method:: __repr__()

      Return repr(self).


   .. py:method:: apply(state)



.. py:class:: PlaylistGenerationProblem(collection, constraints, initial_length=0)

   Bases: :py:obj:`simpleai.search.SearchProblem`

   Create a playlist using local search algorithm.

   .. py:method:: create_input_partitions()

      Divide the dataset into one 'good' and some 'bad' partitions.

      This is done per constraint as the constraints will contradict each
      other somewhat.



   .. py:method:: return_item_to_input_partitions(item)

      Return an item to the partitioned set of input data.


   .. py:method:: generate_random_state()


   .. py:method:: make_append_actions_for_partition(state, partition, count=None)


   .. py:method:: make_remove_actions(state, count=None)


   .. py:method:: post_iteration_hook(state)


   .. py:method:: actions(state)


   .. py:method:: result(state, action)


   .. py:method:: value(state)



.. py:function:: solve(problem, iterations_limit=1000)
