I recently installed simmetrics v 1.6 and i'm having a strange result from euclidean distance function.
I just downloaded the jar and the source, and start playing with the SimpleExample.java file, when trying with the Euclidean distance, it always return 0.0, unless inputing two equal strings.
abb aba return 0.0
abc abd return 0.0
abc abc return 1.0
I tried with a lot of Strings of different sizes, and had the same result.
