Constructor & Destructor Documentation

TwoPointCrossover()

TwoPointCrossover::TwoPointCrossover

(

const Algorithm_Parameters &

params

)

Constructs a TwoPointCrossover object with specified algorithm parameters.

Parameters

params

The algorithm parameters including the crossover rate.

Member Function Documentation

apply()

void TwoPointCrossover::apply ( std::mt19937 & generator )

overridevirtual

Performs the two-point crossover operation.

This method performs a two-point crossover on the two parent individuals to generate an offspring individual. Two crossover points are chosen randomly, and the genetic material from the two parents is combined to create the offspring.

Parameters

generator

The random number generator used to determine the crossover points.

Implements Operator.

setIndividual()

void TwoPointCrossover::setIndividual ( Individual & individual )

inlinevirtual

Sets the individual for the operator.

This method is not used by the TwoPointCrossover operator.

Parameters

individual

The individual to be set.

Implements Operator.

setParents()

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

overridevirtual

Sets the parents and offspring for the crossover operation.

Parameters

offspring	The offspring individual to be generated.
parent1	The first parent individual.
parent2	The second parent individual.

Implements Operator.

setPopulation()

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

inlinevirtual

Sets the population and selected vectors for the selection operation.

This method is not used by the TwoPointCrossover operator.

Parameters

population	The vector of individuals in the population.
selected	The vector of selected individuals.

Implements Operator.

Field Documentation

parent2

const Individual* TwoPointCrossover::parent2

private

Pointer to the second parent individual
