public interface SequenceDistanceMeasurerDouble
Implement this interface, SequenceDistanceMeasurerDouble, to define a distance metric for
sequences. A sequence may have duplicate elements, unlike a Permutation which must have unique
elements. Some SequenceDistanceMeasurers may require the pair of sequences to be the same length,
while others do not have that requirement. Some SequenceDistanceMeasurers may require the pair of
sequences to contain the same set of elements, while others do not have that requirement.
Implementations of this interface compute distances that are floatingpoint valued.
If your sequences are guaranteed not to contain duplicates, and the pair is guaranteed to
contain the same set of elements, and are of the same length, then consider instead using the
classes that implement the PermutationDistanceMeasurerDouble
interface. Those classes are specifically for distance between
permutations of the integers from 0 to N1.
