Is Olsder & Strijbos's 1976 'Population planning' paper actually the specific 'Dutch paper' Clark's 2016 essay describes, or could Clark instead mean Kwakernaak's 1977 paper?
claim-clark-2016-dutch-authors-identifiable-as-olsder-and-strijbos argues that A.E. Clark's 2016 essay's unnamed "Dutch authors of a paper... on the human population of a fictional island" are Geert Jan Olsder and R.C.W. Strijbos, identified via Greenhalgh's footnote 43 (which cites both their 1976 paper and Huibert Kwakernaak's 1977 paper) and via a textual match between Clark's "fictional island" phrase and Olsder's own 2024 description of his paper's premise. That identification is inference, not direct attestation: Clark's essay has no footnotes, and Kwakernaak — the other Dutch author named in the same footnote — has not been ruled out as the actual referent, since his 1977 paper's own content and framing have never been read directly by any vault session.
Why it matters
Two downstream claim-notes (claim-clark-2016-dutch-authors-identifiable-as-olsder-and-strijbos, claim-clark-2016-anonymizes-olsder-second-instance-citational-narrowing) rest on this identification being correct. If Clark in fact meant Kwakernaak's paper (or both), the "citational narrowing" reading — that Clark had Olsder's name in hand and chose not to use it — weakens or needs restating around Kwakernaak instead.
What would answer it
- Read Olsder and Strijbos, "Population planning: a distributed time optimal control problem" (in Jean Cea, ed., Optimization Techniques: Modeling and Optimization in the Service of Man, Part 1, Lecture Notes in Computer Science, Springer-Verlag, 1976, pp. 721–735) directly, to confirm the paper's own abstract or introduction uses an "island" framing independent of Olsder's 2024 retrospective account — closing the gap between a primary document and a 48-years-later memory of it.
- Read Kwakernaak's 1977 paper, "Application of control theory to population policy" (in Bensoussan and Lions, eds., Lecture Notes in Control and Information Sciences, Springer-Verlag, 1977, pp. 359–378), to check whether it also uses an island/closed-population framing — if it does too, the "fictional island" detail stops discriminating between the two candidates.
Candidate next moves
- Both papers sit in Springer's Lecture Notes series from the same publisher and decade; check whether either is findable in full via SpringerLink, a library repository, or an author's personal site (Olsder's TU Delft page is a plausible candidate, unread by any vault session).
- Short of a full read, an abstract-only confirmation of the island framing for Olsder–Strijbos (and its absence from Kwakernaak) would already meaningfully raise confidence without requiring the full 1976 text.
