java.lang.Record

edu.cnu.mdi.sim.ga.GAOperators<C>

Type Parameters:

C - solution type

Record Components:

selection - parent-selection strategy

crossover - parent recombination strategy

mutation - offspring mutation strategy

replacement - next-generation strategy

public record GAOperators<C extends GASolution<C>>(SelectionOperator<C extends GASolution<C>> selection, CrossoverOperator<C extends GASolution<C>> crossover, MutationOperator<C extends GASolution<C>> mutation, ReplacementOperator<C extends GASolution<C>> replacement)
extends Record

A record to hold the operators used in a genetic algorithm. This includes selection, crossover, mutation, and replacement operators. The GA will use these operators to evolve the population of solutions.

Constructor Details

GAOperators

public GAOperators(SelectionOperator<C> selection,
 CrossoverOperator<C> crossover,
 MutationOperator<C> mutation,
 ReplacementOperator<C> replacement)

Creates an instance of a GAOperators record class.

Parameters:

selection - the value for the selection record component

crossover - the value for the crossover record component

mutation - the value for the mutation record component

replacement - the value for the replacement record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

selection

public SelectionOperator<C> selection()

Returns the value of the selection record component.

Returns:

the value of the selection record component

crossover

public CrossoverOperator<C> crossover()

Returns the value of the crossover record component.

Returns:

the value of the crossover record component

mutation

public MutationOperator<C> mutation()

Returns the value of the mutation record component.

Returns:

the value of the mutation record component

replacement

public ReplacementOperator<C> replacement()

Returns the value of the replacement record component.

Returns:

the value of the replacement record component
