Each named anchor characterizes an incentive property; none states an algorithm, hardness result, or computational formulation. The proposed positive-mass deviation changes the paper’s individual-incentive question and supplies no computational result to mirror.
fails bit a — no named computational result to mirror
The proposed mirrors concern Theorem 1, Proposition 1, and Theorem 2, but none is a computational result; the paper’s other incentive characterizations do not provide a computational anchor either.
The best honest positive case is a research lead, not an anchor-compliant case. This paper contains no named computational result: it does not classify a problem as tractable or hard, or give an algorithm or computational formulation that it uses to solve one. Its named results are about incentive compatibility.
The closest result is Theorem 1, proved here: for any domain and any deterministic social choice function, strategyproofness is equivalent to monotone strategyproofness, where a report that reverses fewer preference comparisons relative to the true ranking must yield an outcome at least as preferred. Proposition 1, also proved here, gives the corresponding equivalence for stochastic mechanisms on strongly connected domains. Theorem 2, proved here, extends that equivalence to stochastic mechanisms on tight domains. None is a computational anchor of the kind requested.
There is a natural population-level lead: let types be strict rankings over the finite alternatives, let \(\mu\) give each ranking’s share of society, and let a mechanism map \(\mu\) to a lottery. One could ask whether the paper’s monotonicity result survives when a group of mass \(\varepsilon\) changes its reported ranking. But this is a group-deviation question, not the paper’s individual strategyproofness result. If instead an individual deviates in a nonatomic society, the distribution \(\mu\) does not change, so the mechanism’s outcome is unchanged and the incentive condition becomes trivial. The paper’s note that its agent set need not be finite or countable allows infinite sets of agents; it does not supply a mass-based population model or computational question.
The weakest point is decisive: I cannot state a precise continuous problem per qualifying anchor because there are no qualifying anchors. Treating Theorem 1 as one would misrepresent its contribution. The paper’s continuous utility-vector discussion in Proposition 3 is also not a population mirror: it continuizes agents’ type space, while the society remains a collection of agents.
This paper has no named computational result to mirror. Theorem 1, Proposition 1, and Theorem 2 characterize when strategyproofness implies monotone strategyproofness; none gives an algorithm, complexity classification, or computational formulation. Proposition 3 extends an incentive-compatibility argument to utility vectors, so it continuizes an agent’s type space, not the population. That leaves no qualifying anchor for this programme.
The strongest candidate is Theorem 1, paired with a mechanism that maps a distribution \(\mu\) over rankings to a lottery. In a nonatomic society, one person’s report does not change \(\mu\). If the mechanism varies continuously with \(\mu\), that person’s deviation has vanishing effect as the population grows, and the incentive comparison becomes trivial in the limit. Keeping identity in the model preserves an individual’s influence, but then the distribution over preference types no longer describes all information the mechanism may use.
A positive-mass deviation avoids that degeneracy, but changes the strategic unit. The question becomes whether a bloc can profitably misreport, and how bloc size interacts with the Kemeny comparison. The paper explicitly studies incentives from an individual agent’s perspective. A computational problem about coalition size or profitable mass transfers could be worthwhile in its own right, but the paper states no such problem or result; its difficulty would depend on a newly chosen mechanism representation and coalition model. It is therefore a poor continuous mirror of the paper’s contribution.
The negative case is strongest on fit, not on impossibility: one can imagine the authors finding mass-based coalition manipulation interesting. But that would be a new computational research direction, rather than continuizing one of this paper’s computational results.
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.
