public interface NormalizedPermutationDistanceMeasurer
extends NormalizedPermutationDistanceMeasurerDouble, PermutationDistanceMeasurer
```
Implement this interface to define a distance metric for permutations that supports normalizing the distance to the interval [0,1], but where the base distance is an integer value.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`int`	`max(int length)`	Computes the maximum possible distance between permutations of a specified length.

```
default double normalizedDistance(Permutation p1,
                                  Permutation p2)
```
    Measures the distance between two permutations, normalized to the interval [0.0, 1.0].
    
    Specified by:
    
    normalizedDistance in interface NormalizedPermutationDistanceMeasurerDouble
    
    Parameters:
