Class PositionBasedCrossover

java.lang.Object

org.uma.jmetal.operator.crossover.impl.PositionBasedCrossover

All Implemented Interfaces:

Serializable, CrossoverOperator<PermutationSolution<Integer>>, Operator<List<PermutationSolution<Integer>>,List<PermutationSolution<Integer>>>

public class PositionBasedCrossover
extends Object
implements CrossoverOperator<PermutationSolution<Integer>>

Position-Based Crossover operator for permutation-based genetic algorithms. This operator selects random positions to inherit genes from one parent. The remaining genes are filled from the other parent in the order they appear, ensuring a valid permutation without duplicates.
