org.uma.jmetal.operator.crossover.impl.AdvancedDifferentialEvolutionCrossover

All Implemented Interfaces:

Serializable, CrossoverOperator<DoubleSolution>, Operator<List<DoubleSolution>,List<DoubleSolution>>

public class AdvancedDifferentialEvolutionCrossover
extends Object
implements CrossoverOperator<DoubleSolution>

An advanced implementation of Differential Evolution crossover operator supporting multiple variants and parameter adaptation. This implementation is designed to work well with both single and multi-objective optimization problems.

Supported variants include: - RAND_1_BIN: Classic DE/rand/1/bin - RAND_2_BIN: DE/rand/2/bin - CURRENT_TO_RAND_1: Current-to-rand/1 - CURRENT_TO_PBEST_1: Current-to-pbest/1 (JADE variant) - SHADE: Success-History based Adaptive DE

The operator supports parameter adaptation for CR and F parameters when using adaptive variants.
