Hey, thank you for the reply.
Were you not interested in how Nachman and Crowell addressed the problem themselves?
I was. That is partly why I posted here. I don't know enough to find where research is being done on this particular problem. The solutions given in the article are ad-hoc. This is not a problem, since any hypothesis proposed to solve a newly discovered problem will be ad-hoc. As long as evidence can be found to support the hypothesis, I don't see a problem.
The two links you provided are a good start. Are there any other links and info I can read up on?
