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

inlinevirtual

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

Implements libevocosm::landscape< function_solution >.
