Functions

inline fun <V, F> CellEvolveScope<V, F>.mutation(chance: Double, mutation: (chromosome: Chromosome<V, F>) -> Unit)

Performs a mutation step for population in CellularGA that modify in-place the input chromosomes. Mutates CellEvolveScope.cell.

mutFlipBit

@JvmName(name = "mutFlipBitBooleanArray")

fun <F> CellEvolveScope<BooleanArray, F>.mutFlipBit(chance: Double, flipBitChance: Double)

@JvmName(name = "mutFlipBitIntArray")

fun <F> CellEvolveScope<IntArray, F>.mutFlipBit(chance: Double, flipBitChance: Double)

Flip the value of the attributes of the input chromosome. The chromosome is expected to be a BooleanArray. This mutation is usually applied on boolean individuals.

mutGaussian

fun <F> CellEvolveScope<DoubleArray, F>.mutGaussian(mean: Double, stddev: Double, chance: Double, gaussianChance: Double)

Applies a gaussian mutation of mean mean and standard deviation stddev on the input chromosome. This mutation expects Chromosome.value of floating point numbers.

mutPolynomialBounded

fun <F> CellEvolveScope<DoubleArray, F>.mutPolynomialBounded(eta: Double, low: Double, up: Double, chance: Double, polynomialBoundedChance: Double)

Polynomial mutation as implemented in original NSGA-II algorithm in C by Deb. This mutation expects Chromosome.value of floating point numbers.

fun <T, F> CellEvolveScope<MutableList<T>, F>.mutShuffleIndexes(chance: Double, shuffleIndexesChance: Double)

Executes a shuffle the attributes of the input chromosome. Usually this mutation is applied on vector of indices.

mutUniform

@JvmName(name = "mutUniformDoubleArray")
