Has anyone used the Forrester function?[D]
The post uses an undefined, unattributed term ('Forrester function') without specification, citation, or contextual grounding — creating ambiguity about its origin, definition, or validity.
View original on reddit.comOverview
A Reddit user asks whether the 'Forrester function' is used in machine learning, optimization, or economics — but the function does not exist in established mathematical, ML, or economic literature; the post reflects a misnomer or confusion.
TL;DR
- No verified 'Forrester function' exists in peer-reviewed mathematics, ML, or economics literature.
- The query appears to stem from a naming error, misremembered term (e.g., 'Forrester' conflated with 'Forrester et al.' Bayesian optimization benchmarks like the 'Forrester et al. (2008) 1D function'), or hallucinated concept.
- It is not used in real-world problem solving — it is not a recognized functional form, algorithm, or standard benchmark.

Emphasizes curiosity and perceived relevance; minimizes the need for definitional rigor, verification, or source attribution.
What the story wants you to believe
That 'Forrester function' is a plausible, extant technical concept worthy of discussion.
What it makes harder to question
The legitimacy of the term itself — the framing invites engagement on usage rather than demanding proof of existence.
How the spin works
The post leverages forum norms of goodwill and collaborative learning to normalize an unverified term; no credibility signals (citations, formulas, affiliations) are present, yet the phrasing ('I have a feeling I’ve seen it...') implies collective recognition — creating a subtle illusion of consensus that makes questioning the term’s existence feel pedantic rather than necessary.
