newbie question about DNA and cells

[Louis Hom]

There may be another interesting twist to the relationship between cell 
biology and the traveling salesman problem.  Namely, how do cells go from 
stem cell to fully differentiated cell.  Okay, so you may or may not have 
distinct, dicrete states/nodes along the way, but there are conditions 
that must be met and there may be interesting analogies.
