Constructor Detail

ReverseMutator

public ReverseMutator()

Constructor.

ReverseMutator

public ReverseMutator(float rangePercentage)

Constructor with random range.

Parameters:

rangePercentage - percentage value of the length of a randomly selected range to reverse

ReverseMutator

public ReverseMutator(int lBound,
                      int uBound)

Constructor with lower and upper reverse bound.

Parameters:

lBound - lower bound for reversing

uBound - upper bound for reversing

Method Detail

mutate

public int[] mutate(int[] array)

Reverses an array of integers. The reverse is done dependent on lowerBound and upperBound.

Specified by:

mutate in class IntegerArrayMutator

Parameters:

array - array to be reversed

Returns:

mutated array

randomRange

protected int[] randomRange(int length)

Helper for calculating a valid reverse range, dependent from length of array and percentage value.

Parameters:

length - length of the array

Returns:

integer array with lower and upper bound
