Detailed Description

Abstract base class for genetic algorithm operators.

The Operator class provides an abstract interface for genetic algorithm operators. It defines a pure virtual function apply(), which must be implemented by derived classes. This class serves as a base for various types of genetic algorithm operators, such as selection, crossover, and mutation.

Constructor & Destructor Documentation

~Operator()

virtual Operator::~Operator ( )

virtualdefault

Virtual destructor for the Operator class.

The virtual destructor ensures that derived class destructors are called correctly when an object is deleted through a base class pointer.

Member Function Documentation

apply()

virtual void Operator::apply ( std::mt19937 & generator )

pure virtual

Pure virtual function to apply the operator.

This function must be implemented by derived classes to perform the specific operation of the genetic algorithm operator.

Implemented in GenProgMutation, PureSinglePointCrossover, TwoPointCrossover, UniformCrossover, GuidedMutation, NaryTournamentSelection, RankSelection, and RouletteWheelSelection.

setIndividual()

virtual void Operator::setIndividual ( Individual & individual )

pure virtual

Sets the individual for the operator.

This function sets the individual for the operator. It is used to provide the operator with the necessary data to perform its operation on a single individual.

Parameters

individual

The individual to operate on.

Implemented in PureSinglePointCrossover, TwoPointCrossover, UniformCrossover, NaryTournamentSelection, RankSelection, RouletteWheelSelection, GenProgMutation, and GuidedMutation.

setParents()

virtual void Operator::setParents ( Individual & offspring, const Individual & parent1, const Individual & parent2 )

pure virtual

Sets the parents for the operator.

This function sets the parents for the operator. It is used to provide the operator with the necessary data to perform its operation on two parent individuals.

Parameters

parent1	The first parent individual.
parent2	The second parent individual.

Implemented in GenProgMutation, GuidedMutation, NaryTournamentSelection, RankSelection, RouletteWheelSelection, PureSinglePointCrossover, TwoPointCrossover, and UniformCrossover.

setPopulation()

virtual void Operator::setPopulation ( const std::vector< Individual > & population, std::vector< Individual > & selected )

pure virtual

Sets the population and selected individuals for the operator.

This function sets the population and selected individuals for the operator. It is used to provide the operator with the necessary data to perform its operation.

Parameters

population	The population of individuals to operate on.
selected	The selected individuals to store the results of the operation.

Implemented in PureSinglePointCrossover, TwoPointCrossover, UniformCrossover, GenProgMutation, GuidedMutation, RouletteWheelSelection, NaryTournamentSelection, and RankSelection.
