Method Detail

mutate

public double[] mutate(double[] individual)

Description copied from interface: Mutator

Creates a mutant of the given individual.

The general contract is to not modify the given individual, but return a mutated copy.

Specified by:

mutate in interface Mutator<double[]>

Parameters:

individual - the individual to mutate

Returns:

the mutant of the passed individual
