Phil, I'll have to give your question a bit more thought but my first guess was that it's more like a small, directed perturbation in a dynamic system in an attempt to push the state variables into a different quasi-stable basin of attraction. The "accidentally have an effect opposite the one intended" part may be a clue that there are "poles in the right-hand plane"--to borrow the control-engineering phrase. I've got a deadline to meet tonight so I may not be able to get back to this until tomorrow but I thought I should at least mention this so the dynamical systems gurus can address your question in the interim. --Ross ____________________________________________________________________________________ Do you Yahoo!?
