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.
|
inline |
Creates a new landscape with a given fitness function.
a_function | function to be tested |
a_listener | a listener for events during testing |
|
inline |
Satisfies the requirements of the base class; does nothing at this time.
|
inlinevirtual |
Tests a single chromosome for fitness by calling the fitness function provided in the constructor.
a_organism | the organism to be tested by the landscape. |
a_verbose | should this test produce lots of output? |
Implements libevocosm::landscape< function_solution >.
