Theorem 3 is an asymptotic convergence characterization, and Theorem 5 is an impossibility result about social-choice properties; neither gives an algorithm, runtime bound, hardness result, or computational formulation used to compute. The proponent acknowledges that the paper has no named computational result, so the proposed heterogeneous-public recurrence is a new extension rather than a continuous mirror of a computational result in this paper.
fails bit a — no named computational result to mirror
No computational result is mirrored. Theorems 1–4 characterize convergence, Theorems 5 and 7 state impossibility results about properties, and Theorem 6 concerns incentives; the experiments provide empirical evidence without a stated guarantee.
The strongest positive case is a plausible high-multiplicity extension of the paper’s public-curation model. Imagine a very large user community whose members share a small number \(\tau\) of complete preference types: each type \(t\) has the same Bradley–Terry strength vector \(w_t\) over a finite catalogue \(X\) of response classes. Its mass \(\mu_t\) is the fraction of users of that type. The regime is many users with \(n \gg \tau\), as might occur when people use a small set of shared evaluation rubrics. The Owner remains a single institutional curator.
One precise candidate problem is Finite-Type Recursive-Curation Support. The input is \(X\), rational initial output mass \(p_0\), rational type masses \(\mu_t\), positive rational BT strengths for the Owner and each type, pool sizes \(K,M\), and a subset \(S\subseteq X\). Define
\[
H_{q,k,w}(x)=\mathbb E_{Y_1,\ldots,Y_{k-1}\sim q}
\left[\frac{k\,w(x)}{w(x)+\sum_j w(Y_j)}\right].
\]
At each round, the Owner produces \(q(x)=p(x)H_{p,K,w_O}(x)\); the community then applies its type-specific curation, averaged by population mass:
\[
p'(x)=q(x)\sum_t\mu_t H_{q,M,w_t}(x).
\]
The question is whether the mass outside \(S\) vanishes in the limit, that is, whether \(\lim_{n\to\infty}p_n(X\setminus S)=0\). A solution is a yes-or-no answer. This is a concrete population-continuous dynamics problem, and it is close to Theorem 3’s question about which content survives. But the paper does not analyze this heterogeneous-public recurrence; its “Public” has one reward function. I would leave its complexity classification open rather than infer one from the paper.
That distinction is decisive for the requested anchors: the paper contains no named computational-complexity result of the required kind. Theorem 3, proved here, says that with overlapping but distinct optimal sets, mass outside every neighborhood of their intersection decays exponentially, and the limiting distribution is the initial distribution restricted and renormalized to that intersection. That is a convergence characterization, not an algorithm or complexity classification. Theorem 5, also proved here, is an impossibility result about simultaneously maintaining mass in both disagreement regions, symmetric influence, and independence from the initialization; it is a social-choice property theorem, not a computational hardness result. The other numbered results concern convergence, incentives, or axiomatic properties. None establishes membership in P, hardness, an FPT result, or computes with a finite optimization formulation.
So the proposed problem is a credible research direction for the authors’ model, but it is not a continuous mirror anchored in one of this paper’s named computational results. Also, the paper already makes the output a distribution over content; that is outcome-space continuity. The population mirror would come only from making its aggregated Public explicit as a mass distribution over preference types.
The strongest objection is that the paper has no named computational result to mirror. Theorem 3 characterizes the limit of a recursive curation process; Theorem 5 rules out a combination of social-choice properties. The other numbered results concern convergence, incentives, and axioms. None asks for an algorithm or classifies a computational problem. That leaves no result whose complexity landscape continuization could reveal.
The proposed finite-type recurrence is the best rescue, and its population story is plausible: many users could share a small number of preference rubrics. The problem is what it has to change to make that population matter. If the Public keeps the paper’s single preference function, the mass distribution over users has no effect on the update. If users have heterogeneous BT strengths and their curation outcomes are averaged by type mass, the update changes from the paper’s two-curator mechanism to a new, heterogeneous-community mechanism. That may be a worthwhile extension, but it does not compute or classify Theorem 3’s result: it asks for a new characterization of an infinite-horizon nonlinear process.
The same gap applies to Theorem 5. Its impossibility concerns two curator roles, not a population whose multiplicity could be varied. Making the Public a continuum of preference types would require new definitions of coverage, influence symmetry, and initialization independence. The resulting theorem could be interesting, but it would be a new social-choice question rather than a population mirror of the stated one.
I would not dismiss the proposed extension on the grounds that users are aggregated, or that the output space is already continuous. The proposed types can be complete, and their masses can genuinely represent a large community. Nor can I show that the resulting decision problem is uninteresting: with a finite catalogue and rational inputs, asking whether mass outside \(S\) vanishes is a well-defined candidate problem. The negative case is therefore strongest as a case about *fit*: the paper offers analytic dynamics, not computational results, and the best population formulation changes those dynamics to create a new problem. If a plausible new extension counts as a mirror for this programme, that case is not airtight.
The adversarial triple: the proponent anchors on up to three named results; the opponent sees that case and must defeat every anchor; the judge decides which case convinced it. These are the pipeline’s own outputs, generated by tools/triple_run.py — no human edited them. The paper’s own text is not reproduced here beyond the quoted statement above.
