I imagine (contradict me if I'm wrong) that your problem is a complex<br>variant of Conway's <a href="http://en.wikipedia.org/wiki/Conway%27s_Game_of_Life">Game of Life</a>. But even this simple generating algorithm<br>
defies any attempt of analysis except by "simulate and observe".<br><br>So, I doubt that your (presumably much more complex) problem can<br>be solved with planner/solver.<br><br>-W<br><br><br>On Fri, Jan 22, 2010 at 6:39 PM, drooler <span dir="ltr"><<a href="mailto:david_wynter@yahoo.com">david_wynter@yahoo.com</a>></span> wrote:<br>

Thx for the answer to the 1st question.<br>
<br>
The second question should have been more precise. I suppose what I do not<br>
'get' yet is how the Planner interacts with the fact that the generations<br>
change. The examples for the solver show it working against a static set of<br>
facts, the planner move mechanism is the thing that varies the facts. My<br>
need to iterate over a number of generations to be able to see how affective<br>
my 'nutrients' are does not sit well with how the planner/solver works on a<br>
static set of facts.<br>
<br>
If I rephrase it might help. In my case the selection of which generation is<br>
the current one is controlled by my rules or a fireAllRules() iteration.<br>
Then the 'score' in my case can only be determined after several generations<br>
have been interated through making each 'current' in turn. I currently have<br>
a object that keeps the current 'score' and high score as I iterate through<br>
the generations. I want to see how varying the parameters of the 'nutrients'<br>
fed to each organism affects the 'health' over several generations. I feel I<br>
have one too many dimensions in my problem space here to be able to use the<br>
Solver/Planner. But maybe with some tweaking of the objects that describe my<br>
problem I take take advantage of it. Sorry to be a bit vague, I might just<br>
have to experiment with using it.<br>
