All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

Best1Bin

public class Rand1Bin
extends DEOptimCellFactory

The Rand-1-Bin rule is defined by:

• mutation by adding a scaled, randomly sampled vector difference to a third vector (differential mutation);
• crossover by performing a uniform crossover (discrete recombination).
