I'm clearly not going to understand your motivation so I think I'll stop here.

(edit: There is absolutely nothing stopping heuristics and DP being combined; in fact they have to be in eg. database optimisation. A pure DP solution to query optimisation will be optimal, but will take unbounded (lthough finite) time, which is unacceptable. DP and heuristics are combined to both guide the DP search and bound it after a strict time (usually a couple of seconds CPU) by when it is hopefully 'good enough').
