Theorem 6 provides the closest computational anchor through its recursive construction, but its query relevance and strategic guarantees rely on pivotal individual bidders. In an atomless population, an individual's report has zero effect, changing the strategic problem the theorem addresses. Theorem 7's welfare guarantee could motivate a mass-market allocation problem, but that would be a new extension rather than a computational result of this paper.
fails bit b-changes — the continuum limit changes the question
No anchor yields a surviving mirror: Theorem 6's construction concerns individual query incentives, Theorem 7 proves finite-auction allocation efficiency, and Theorem 4 is an implementation impossibility.
I can’t make a compliant positive case from this paper: it contains no named result asserting a computational complexity classification or an algorithmic formulation that the paper computes with. Its numbered theorems concern incentive properties, existence, and allocation efficiency.
The nearest candidate is Theorem 6, proved here: for any \(N,M,\Theta\), there exists a VCG-equivalent-in-expectation mechanism with no irrelevant query. It is constructive, but it does not establish tractability or analyze the complexity of constructing the mechanism. Theorem 7, also proved here, says the proposed Japanese spectrum auction achieves a Pareto-efficient allocation; it proves a welfare property, not a computational result. Theorem 4 is an impossibility result about irrelevant queries, not computational hardness.
A possible population-level extension would take bidder valuation schedules as types, \(\mu_t\) as the fraction of operators with schedule \(t\), and scale spectrum supply with the population. One could ask for an adaptive auction that elicits enough aggregate demand to select a welfare-maximizing allocation and sets expected VCG transfers. But that is an unanchored new question, not a continuous mirror of a qualifying computational result in this paper.
Its weakest point is also fundamental: in a nonatomic population, one bidder’s report has no effect on aggregate demand, so the individual incentives and VCG externality payments central to the paper can disappear. The auction setting offers a plausible place to explore continuization, but the paper supplies no eligible computational anchor for this case.
The proponent is right about the paper’s main weakness as a ChoCo candidate: none of its numbered results classifies the complexity of a computational problem. Theorem 2 proves an equilibrium property; Theorem 4 proves that some exact VCG mechanisms must ask an irrelevant query; Theorem 6 gives a recursive construction; and Theorem 7 proves an allocation is Pareto efficient. Theorem 6 is the closest anchor, but it gives no running-time or query-complexity bound. Its construction can branch across the product of the participants’ type spaces. That is a constructive mechanism result, not a complexity result of the kind the programme is meant to mirror.
The best replacement would be a computational problem about finding a small or low-leakage query tree that implements efficient allocations and expected VCG transfers for a society with distribution \(\mu\) over complete valuation schedules, perhaps with spectrum supply scaled per capita. That is more promising than simply asking for a continuum version of the paper’s application. But it introduces the central question the paper is about—whether each participant has an incentive to answer queries sincerely—and that question changes sharply under population continuization. In an atomless population, one participant has zero mass and cannot affect aggregate demand or the allocation. Their report cannot meaningfully affect their transfer either, so the paper’s notion of a relevant query loses its strategic force. Querying a positive-mass block restores influence only by treating the block as a strategic bidder, changing the unit of agency that the model was designed to study. With iid types and a known prior, the aggregate type distribution also converges to the prior, so the iterative discovery problem itself largely disappears.
The spectrum-auction result does not rescue the case: it concerns a finite set of operators and indivisible licenses. Scaling both participants and supply might yield a sensible large-market model, but its tractability would be a new computational question, not a mirror of Theorem 7’s welfare claim. Nor does the paper’s note that individual type spaces can be continuous supply the missing population limit; continuizing possible valuations is different from making the society continuous.
So the proposed anchors do not establish a worthwhile continuous mirror under ChoCo’s computational-result gate. The negative case is strongest as a judgment about this paper. It is weaker as a universal claim: a newly formulated query-tree optimization problem might be worth studying, and the paper’s authors might recognize it as a useful extension. But that possibility does not turn the paper’s existence, incentive, and welfare theorems into computational results to mirror.
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.
