Method Detail

doMutate

protected final io.vavr.collection.Array<java.lang.Double> doMutate(io.vavr.collection.Array<java.lang.Double> representation,
                                                                    int index)

Description copied from class: StochasticMutate

Mutate the representation at the given index.

This method purpose is to allow efficient unboxing in case of representations of primitives.

Specified by:

doMutate in class StochasticMutate<java.lang.Double,DoubleVectorSolution>

Parameters:

representation - the representation to be mutated

index - the index at which mutation should occur

Returns:

the new representation of the solution

doMutate

protected abstract double doMutate(double value)

Perform the actual mutation on a primitive double.

Parameters:

value - The old value

Returns:

a mutated value

isMemoized

public boolean isMemoized()
