I've recently had another result which makes me question the randomness of
the numbers being generated by the mersenne twister in MASON.

 

I've got two classes that I am setting up the Mersenne twister in
separately, because originally I was getting a series of identical numbers
in when trying to use the random numbers from the main class.

----------

 

public ABCycle(long seed)        {

            

                        super (new MersenneTwisterFast(seed), new
Schedule(5));

            }

 

ABCycle abc = new ABCycle(System.currentTimeMillis());

 

 

-----------------------

 

MersenneTwisterFast random = new MersenneTwisterFast();

 

random.setSeed(System.currentTimeMillis() + id);

                        tp = maxTP * random.nextDouble();

 

------

 

 

Does anything in my code look strange? My results that are emerging have
some differentiation between runs, but the standard deviations are
miniscule. I feel like one of the randoms is working, but others are not.
