Detailed Description

template<typename OrganismType, typename LandscapeType>
class libevocosm::reporter< OrganismType, LandscapeType >

A reporter can be many things; essentially, after fitness testing, the standard evocosm implementation calls a reporter to display information about the population and to find out if the population has reached some "final" or "finished" state.

Parameters:
OrganismType- The type of organism

Constructor & Destructor Documentation

template<typename OrganismType, typename LandscapeType>
libevocosm::reporter< OrganismType, LandscapeType >::reporter ( listener a_listener) [inline]

Creates a new reporter object

Parameters:
a_listener- a listener for events
template<typename OrganismType, typename LandscapeType>
virtual libevocosm::reporter< OrganismType, LandscapeType >::~reporter ( ) [inline, virtual]

A virtual destructor. By default, it does nothing; this is a placeholder that identifies this class as a potential base, ensuring that objects of a derived class will have their destructors called if they are destroyed through a base-class pointer.


Member Function Documentation

template<typename OrganismType, typename LandscapeType>
virtual bool libevocosm::reporter< OrganismType, LandscapeType >::report ( const vector< vector< OrganismType > > &  a_population,
size_t  a_iteration,
double &  a_fitness,
bool  a_finished = false 
) [pure virtual]

The report method can do almost anything. In most case, it will display the "best" chromosome, draw a progress graph, or notify the user that another generation has passed. The return value tells an evocosm whether to continue evolution (changes in the population) or not.

Parameters:
a_population- A population of organisms
a_iteration- Iteration count for this report
a_fitness- Assigned the fitness value; implementation-defined
a_finished- When true, indicates that this is the last report for a given run
Returns:
true if the evocosm should evolve the population more; false if no evolution is required.
