After fitness testing, the Evocosm invokes an analyzer. At a minimum, the analyzer determines if the population has reached a "final" or "finished" state.
OrganismType | - The type of organism |
|
inline |
Creates a new reporter object
a_listener | - a listener for events |
|
inlinevirtual |
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.

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 evolving or not. The default implementation simply watches to see if a maximum number of iterations ahve been perfromed.
a_population | - A population of organisms |
a_iteration | - Iteration count for this report |
