i was thinking vaguely that the successful applications might be more likely to pop up in scenarios where problems can be clearly defined and are unlikely to change. i've worked on optimisation projects in business contexts where the requirements and the problems tend to change somewhat from month to month - this doesn't make for relaxing / hugely successful projects if the requirements changes bend the problem into territory that breaks the effectiveness of the solution approach.
