)

Constructs a RankSelection object with specified algorithm parameters.

Parameters

params

The algorithm parameters including the population size.

Member Function Documentation

apply()

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

overridevirtual

Performs the rank-based selection operation.

This method selects individuals from the population based on their rank and stores the selected individuals in the provided vector.

Parameters

generator

The random number generator used for selection.

Implements Operator.

Here is the caller graph for this function:

setIndividual()

void RankSelection::setIndividual ( Individual & individual )

inlinevirtual

Sets the individual to be selected.

This method sets the individual to be selected from the population.

Parameters

individual

The individual to be selected.

Implements Operator.

setParents()

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

inlinevirtual

Sets the parents and offspring for the selection operation.

This method is not used by the RankSelection operator.

Parameters

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

Implements Operator.

setPopulation()

void RankSelection::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:
