Constructor & Destructor Documentation

NaryTournamentSelection()

NaryTournamentSelection::NaryTournamentSelection

(

const Algorithm_Parameters &

params

)

Constructs an NaryTournamentSelection object with specified algorithm parameters.

Parameters

params

The algorithm parameters including the tournament size.

Member Function Documentation

apply()

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

overridevirtual

Performs the n-ary tournament selection operation.

This method selects individuals from the population based on n-ary tournament competition and stores the selected individuals in the provided vector.

Parameters

generator

The random number generator used for selecting individuals.

Implements Operator.

Here is the caller graph for this function:

setIndividual()

void NaryTournamentSelection::setIndividual ( Individual & individual )

inlinevirtual

Sets the individual to be mutated.

This method sets the individual to be mutated by the operator.

Parameters

individual

The individual to be mutated.

Implements Operator.

setParents()

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

inlinevirtual

Sets the parents and offspring for the crossover operation.

This method is not used by the NaryTournamentSelection operator.

Parameters

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

Implements Operator.

setPopulation()

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

overridevirtual

Sets the population and selected vectors for the selection operation.

Parameters

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

Implements Operator.

Here is the caller graph for this function:

Field Documentation

population

const std::vector<Individual>* NaryTournamentSelection::population

private
