ValueServer not deterministic for a fixed random number seed
------------------------------------------------------------
Key: MATH-654
URL: https://issues.apache.org/jira/browse/MATH-654
Project: Commons Math
Issue Type: Bug
Affects Versions: 2.2
Reporter: David James
I have built an agent-based model using the Apache Commons Math library, which
has come in handy.
The ValueServer seemed particularly helpful, as explained at:
http://commons.apache.org/math/userguide/random.html
My simulation needs repeatable randomness, so I used this form of the
ValueServer constructor:
ValueServer(RandomData randomData)
Construct a ValueServer instance using a RandomData as its source of random
data.
//
http://commons.apache.org/math/api-2.2/org/apache/commons/math/random/ValueServer.html
However, in my simulation, I found that the ValueServer did not act
deterministically if I supplied the same random number seed.
I have not inspected the source code, but I suspect that the ValueServer is not
using the `randomData` generator correctly. If it was, then it should be
deterministic.
