Detailed Description

A "fitness" landscape defines the environment in which an organism competes for survival. In the case of function optimization, the "test" is (obviously!) a function.

Constructor & Destructor Documentation

libevocosm::function_landscape::function_landscape	(	t_function *	a_function,
		listener< function_solution > &	a_listener
	)		[inline]

Creates a new landscape with a given fitness function.

Parameters:

a_function	function to be tested
a_listener	a listener for events during testing

libevocosm::function_landscape::~function_landscape

(

)

[inline]

Satisfies the requirements of the base class; does nothing at this time.

Member Function Documentation

virtual double libevocosm::function_landscape::test	(	function_solution &	a_organism,
		bool	a_verbose = false
	)		const [inline, virtual]

Tests a single chromosome for fitness by calling the fitness function provided in the constructor.

Parameters:

a_organism	the organism to be tested by the landscape.
a_verbose	should this test produce lots of output?

Returns:

Computed fitness for this organism
