Yes, this is what is done in the classes that already have a constructor
argument, the tests do use it and use hard coded funny constants to se
It is also desirable to have a way to inject a test generator so that test
cases can be made deterministic.
In Mahout, we did this by having a static method in a utility class for
getting a standard generator for either testing or normal operation. This
has turned out very well.

Hi all,
Some of our algorithms do use random number generation. I quickly
reviewed them and found different ways to use them.
Genetic algorithm use a single static RandomGenerator shared by all
instances. It default to JDKRandomGenerator and can be reset by calling
setRandomGenerator.
