Detailed Description

Implements chance-based mutation of solutions.

Constructor & Destructor Documentation

function_mutator() [1/2]

libevocosm::function_mutator::function_mutator ( double  a_mutation_rate )

inline

Creates a new mutator with a given mutation rate.

function_mutator() [2/2]

libevocosm::function_mutator::function_mutator ( const function_mutator &  a_source )

inline

Duplicates an existing object.

Parameters

a_source

- The source object

~function_mutator()

virtual libevocosm::function_mutator::~function_mutator ( )

inlinevirtual

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

Member Function Documentation

mutate()

void libevocosm::function_mutator::mutate ( vector< function_solution > &  a_population )

virtual

Mutates a solution using the facilities provided by g_evoreal.

Parameters

a_population

- Solutions to be mutated

Implements libevocosm::mutator< function_solution >.

mutation_rate()

double libevocosm::function_mutator::mutation_rate ( ) const

inline

Returns the mutation rate set for this mutator.

Returns

Mutation rate

operator=()

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

inline

Assigns the state of one object to another.

Parameters

a_source

- The source object

Returns

A reference to this
