Richard, Any problem can be stated as search for results that satisfy given constraints. What you state here doesn't seem to contradict what I wrote before. In following paragraph you describe it:

So, you ask if it's possible to find local rule given global behavior. It's obviously possible to get global behavior once you have local rules. Which essentially what I wrote before, and what Josh exemplified by his brute force initial conditions enumerator. I try not to be 'dismissive', which suggests kind of oversight, but I also try not to ignore inconsistencies.
