dev.nm.solver.multivariate.geneticalgorithm.minimizer.deoptim.Rand1Bin.DeRand1BinCell

All Implemented Interfaces:

Chromosome, Comparable<Chromosome>

Direct Known Subclasses:

Best2Bin.DeBest2BinCell

Enclosing class:

Rand1Bin

public class Rand1Bin.DeRand1BinCell
extends DEOptimCellFactory.DeOptimCell

This chromosome defines the Rand-1-Bin rule. The two genetic operations of this chromosome are:

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