:mod:`Consts` -- constants module
============================================================================

Pyevolve have defaults in all genetic operators, settings and etc, this is an issue to helps the user in the API use and minimize the source code needed to make simple things. In the module :mod:`Consts`, you will find those defaults settings. You are encouraged to see the constants, but not to change directly on the module, there are methods for this.

General constants
----------------------------------------------------------------------------

   The default log filename.

.. attribute:: CDefLogLevel

.. attribute:: sortType
   
   Sort type, raw or scaled.

   Example:

      >>> sort_type = Consts.sortType["scaled"]

.. attribute:: minimaxType

   The Min/Max type, maximize or minimize the evaluation function.
