Detailed Description
template<class OrganismType>
class libevocosm::evocosm< OrganismType >
This is where it all comes together: An evocosm binds a evocosm of organisms to a set of objects that define how those organisms evolve.
- Parameters
-
OrganismType - The type of organism
Constructor & Destructor Documentation
§ evocosm() [1/2]
| libevocosm::evocosm< OrganismType >::evocosm | ( | vector< OrganismType > & | a_population, |
| landscape< OrganismType > & | a_landscape, | ||
| mutator< OrganismType > & | a_mutator, | ||
| reproducer< OrganismType > & | a_reproducer, | ||
| scaler< OrganismType > & | a_scaler, | ||
| selector< OrganismType > & | a_selector, | ||
| analyzer< OrganismType > & | a_analyzer, | ||
| listener< OrganismType > & | a_listener | ||
| ) |
Creates a new evocosm. Think of an evocosm as a director, a tool for associating organisms with their landscape. Note that these arguments are modifiable references, and that the referenced objects must continue to exist during the lifetime of the evocosm.
- Parameters
-
a_population Initial population of organisms a_landscape Initial set of landscaoes for testing organism fitness a_mutator - A concrete implementation of mutator a_reproducer - A concrete implementation of reproducer a_scaler - A concrete implementation of scaler a_selector - A concrete implementation of selector a_analyzer - A concrete implementation of analyzer a_listener - a listener for events
§ evocosm() [2/2]
| libevocosm::evocosm< OrganismType >::evocosm | ( | const evocosm< OrganismType > & | a_source | ) |
Creates a new evocosm identical to an existing one.
- Parameters
-
a_source - The source object
§ ~evocosm()
|
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
§ get_population()
|
inline |
Use with caution! This function provides direct read-write access to an evocosm's population. This is necessary when the organisms need special manipulation, such as when they can not be randomized by a default constructor.
§ get_sleep_time()
|
inline |
Get the sleep time setting for this listerner. /return current value of sleep time (microseconds)
§ operator=()
| evocosm< OrganismType > & libevocosm::evocosm< OrganismType >::operator= | ( | const evocosm< OrganismType > & | a_source | ) |
Assigns an existing object the state of another.
- Parameters
-
a_source - The source object
- Returns
- Reference to target object
§ run_generation()
|
virtual |
A generation represents a cycle in the life of an evocosm; this function performs one sequence of fitness testing & scaling, reporting, breeding, and mutation. This method can be replaced by in a derived class to define a different processing sequence; the default sequence defined here is good for most evolutionary algorithms I've created.
- Returns
- Returns true when the generation has reached a specific goal.
§ set_sleep_time()
|
inline |
Set the sleep time property value. /param a_sleep_time new value of sleep time (microseconds)
§ yield()
|
inlineprotected |
Evocosm periodically invokes this function to allow other processes to run. In most cases, this will be some sort of platform-specific sleep function, such as usleep.
