The numbered theorems establish incentive properties rather than algorithms, complexity bounds, or computational hardness; the simulations state no computational guarantee. A seller-truthfulness question over online buyer mass is a plausible extension, but it cannot supply the missing computational anchor.
fails bit a — no named computational result to mirror
The proposed mirror concerns the seller-truthfulness impossibility in Theorem 2; it leaves Theorems 1, 3, and 4 and the empirical mechanism comparisons outside the mirror.
The strongest honest positive case is that this paper has a natural high-multiplicity setting, but it has no qualifying computational anchor under your criteria. Its numbered theorems concern mechanism properties, not whether a problem is in P, NP-hard, FPT, or similar; nor does the paper give a computational formulation and then analyze or solve it. So there is no per-anchor continuous problem I can offer without stretching the brief.
The plausible regime is a large city or commuting corridor with many EV drivers seeking reservations. A type could be a driver’s complete valuation vector over station–time pairs together with their arrival window; \(\mu_r\) would be the fraction of incoming drivers of type \(r\). Charging stations could remain a finite set of sellers, with their time-slot capacities scaled to the market. The decision variable would be an online allocation of arriving mass to station–time capacity, and the objective would be total buyer value minus station costs. Repeated commute patterns, fleet schedules, and standard reservation windows could make the number of types \(\tau\) much smaller than the number of drivers. That preserves the paper’s central question—matching dynamically arriving drivers with strategic preferences to strategic charging stations—rather than continuizing its outcomes.
The closest formal result is Theorem 2, proved in the paper: under the stated greedy allocation rule, there is no payment that always makes sellers truthful. Its proof gives a weak-monotonicity violation using one seller, two time slots, and two buyers. A natural follow-on question would be whether that greedy online allocation admits truthful seller payments when buyers arrive as type masses \(\mu_r\), with values over station–time pairs, and stations have costs and capacities per unit mass. A solution would be a payment rule that makes truthful cost reporting optimal for every seller. The paper’s counterexample suggests the impossibility may persist by scaling the two buyer cases into cohorts, but that population result is not established there. More importantly, it is an incentive-compatibility existence question, not a computational-complexity result, so I would not count Theorem 2 as an anchor.
For completeness, the other numbered results are also mechanism properties: Theorem 1, proved here, says the buyer payment is truthful and individually rational for buyers and, under nondecreasing marginal station costs, removes incentives to delay; Theorem 3, proved here, gives seller truthfulness for Reverse Vickrey when the current buyer is known to be the last; and Theorem 4, proved here as a sketch, gives Critical Value truthfulness when sellers have at most one unit per time slot and buyers are interested in only one time slot. None supplies the required computational anchor.
The weak point in the positive case is type support. The paper’s buyer type is a full private valuation matrix, and real drivers’ routes, schedules, and preferences may differ enough that exact types proliferate. Cohort-based demand makes moderate \(\tau\) plausible in some markets, but the paper does not establish that regime or analyze it. So the paper offers a convincing setting for a future continuous-population study, but not an anchor-based case that this paper already delivers the kind of computational result the programme seeks.
The proponent’s central concession is the strongest case against a ChoCo mirror: the paper proves no named result about computational complexity or algorithms. Theorem 2 is an impossibility result about seller truthfulness under a particular allocation rule; Theorems 1, 3, and 4 establish other incentive properties. The greedy allocation rule and the equilibrium simulations add computational machinery, but the paper does not analyze their complexity. Under the programme’s stated criteria, there is no qualifying computational anchor.
The best candidate is a continuous version of Theorem 2: model repeated commuters or fleet drivers as positive-mass cohorts, scale station capacities and costs with mass, and ask whether the greedy allocation admits truthful seller payments. That is a coherent question in a plausible high-multiplicity regime. But it remains a question about incentive compatibility, not computational complexity. Nor does the mass model automatically preserve the paper’s individual online incentives: the aggregate flow does not encode a single driver’s position in the arrival sequence and deviation. Treating each cohort as one strategic player changes the agent model; retaining pointwise individual deviations requires an additional mechanism definition. Either way, the result would be new mechanism-design theory, not a continuous mirror of a computational result in this paper.
Theorem 1’s truthfulness and no-delay claims, and Theorems 3 and 4’s restricted seller-truthfulness claims, do not supply other anchors: they too are mechanism properties rather than complexity results. Cohortifying the two-buyer witness in Theorem 2 might yield a meaningful continuous impossibility question, but that would not turn it into a computational-complexity result.
I would therefore reject this paper as an anchor for the programme. The broader claim that *no scenario* could produce worthwhile continuous computational work is harder to defend: large fleets or commuting corridors could provide sensible repeated types. Such work may be worthwhile, but on the evidence here it would develop a new computational question inspired by the market, rather than continuize a computational result the paper establishes.
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.
