This is not surprising. In fact, this is precisely what you should expect from
a recipe of this nature within the context of DP and why many scholars regard
some aspects of DP as “ art ” rather than science (e.g. Dreyfus and Law, 1977).
The main reason for this unavoidable ambiguity is the fact that the recipe applies
to a vast class of disparate problems. The “ art ” of DP is all about being able
to apply this “ general ” recipe in the context of specific problems.
