public RealChromosome(Real[] genes,
 Function<Real[],Real> fitnessFunction,
 Real[] lowerBounds,
 Real[] upperBounds)

Method Details

getGenes

public List<Real> getGenes()

Description copied from interface: Chromosome

Gets the sequence of genes.

Specified by:

getGenes in interface Chromosome<Real>

Returns:

an unmodifiable list of genes

getFitness

public double getFitness()

Description copied from interface: Chromosome

Calculates the fitness of this chromosome. Higher fitness is better.

Specified by:

getFitness in interface Chromosome<Real>

Returns:

the fitness score

crossover

public List<Chromosome<Real>> crossover(Chromosome<Real> other)

Description copied from interface: Chromosome

Creates a new chromosome by crossing over with another.

Specified by:

crossover in interface Chromosome<Real>

Parameters:

other - the partner chromosome

Returns:

a pair of new chromosomes (offspring)

mutate

public Chromosome<Real> mutate(double probability)

Description copied from interface: Chromosome

Mutates this chromosome.

Specified by:

mutate in interface Chromosome<Real>

Parameters:

probability - chance of mutation per gene

Returns:

a new mutated chromosome
