Detailed Description

Handles reproduction for solutions.

Constructor & Destructor Documentation

function_reproducer() [1/2]

libevocosm::function_reproducer::function_reproducer ( double  p_crossover_rate = 1.0 )

inline

Creates a new reproducer with a given crossover rate.

function_reproducer() [2/2]

libevocosm::function_reproducer::function_reproducer ( const function_reproducer &  a_source )

inline

Duplicates an existing object.

Parameters

a_source

- The source object

~function_reproducer()

virtual libevocosm::function_reproducer::~function_reproducer ( )

inlinevirtual

Satisfies the requirements of the base class; does nothing at this time.

Member Function Documentation

breed()

virtual vector<function_solution> libevocosm::function_reproducer::breed ( const vector< function_solution > &  a_population, size_t  p_limit  )

virtual

Breeds new solutions, by cloning or the combination of elements from parent organisms. By default, the crossover rate is 1.0 (100%), meaning that all children stem from crossover between two parents. The crossover is implemented on a argument-by-argument basis; in other words, crossover occurs between corresponding elements of the parent solutions.

Parameters

a_population	- A population of solutions
p_limit	- Maximum number of children

Returns

A vector containing new "child" chromosomes

Implements libevocosm::reproducer< function_solution >.

crossover_rate()

double libevocosm::function_reproducer::crossover_rate ( ) const

inline

Returns the crossover rate set for this reproducer.

Returns

Crossover rate

operator=()

function_reproducer& libevocosm::function_reproducer::operator= ( const function_reproducer &  a_source )

inline

Assigns the state of one object to another.

Parameters

a_source

- The source object

Returns

A reference to this
