Constructor Detail

IntegerRangeMutation

public IntegerRangeMutation()
Constructor. The mutation propability is set to 0.05 and the mutation range is set to [-10, 10].

IntegerRangeMutation

public IntegerRangeMutation(float propability)
Constructor with mutation propability. The mutation range is set to [-10, 10].
Parameters:
propability - mutation propability

IntegerRangeMutation

public IntegerRangeMutation(float propability,
                            int lowerBound,
                            int upperBound)
Constructor with mutation propability and mutation range. If lowerBound > upperBound, the mutation range is silently set to [-10, 10].
Parameters:
propability - mutation propability
lowerBound - lower bound of mutation range
upperBound - upper bound of mutation range
Method Detail

mutate

public void mutate(Chromosome cr)
            throws MutationException
Performs the mutation.
Overrides:
mutate in class ChromosomeMutation
Parameters:
cr - chromosome of type IntegerChromosome
Throws:
