Enumeration counts are conditional on the construction rules; minimum vapor duty is not universal optimality.
Chapter-level engineering discussion by Vishesh H. Shah and Rakesh Agrawal; paraphrase of printed pp. 274–292.
Systematic configuration generation expands beyond traditional column-order heuristics. Thermally coupled and nonsharp alternatives can change performance, while a screening objective may not capture cost or operability.
