The paper’s only numbered theorem, Theorem 0.1, proves an idealized aggregate-bias inequality but makes no computational or complexity claim. The proposed evaluator-population calibration and mass-transfer robustness questions are plausible new extensions, but neither mirrors a qualifying computational result in this paper.
fails bit a — no named computational result to mirror
No qualifying computational result is covered. Theorem 0.1 gives an idealized bias bound; the proposed population calibration and robustness questions extend the empirical method.
This paper has no eligible computational anchor. Its only numbered theorem is Theorem 0.1, proved here: under an idealized model that shrinks each judge’s bias toward the mean bias, the total expected absolute bias across judges for any model does not increase. That is a bias bound, not a classification of a problem as tractable, hard, or otherwise computationally complex.
UDA’s adaptive Elo updates and neural adapter are presented as a method and evaluated empirically; the paper gives no named complexity result for the underlying problem. A continuous population of judge types might motivate a new question, but it would not mirror a qualifying named result from this paper. Under your anchor requirement, there is no honest per-anchor continuous problem to state.
The proponent is right about one narrow point: Theorem 0.1 is an idealized bias bound, not a complexity result, and the paper gives no complexity analysis of UDA. But that does not establish that there is no worthwhile mirror. The paper’s central contribution is a named computational method with an explicit consensus-training objective and a reported result: UDA reduces disagreement among judges while improving correlation with human rankings. Those provide an algorithmic object to continuize, even if the paper does not itself prove a complexity theorem.
A natural population is the evaluator services used by a large model-evaluation platform. Many services may share a model, version, prompt, rubric, and sampling policy; their type records that full policy, its pairwise judgments and features on a fixed benchmark, and any relevant costs. The mass \(\mu_t\) is the share of evaluation capacity assigned to type \(t\). This is a population of judges, not a continuum of outcomes or prompts. It is also anonymous in the way UDA’s objective is: the loss compares judge trajectories with a collective anchor, and the judge-specific self-output features can be included in the type.
This gives a direct continuous version of UDA’s consensus objective. If \(R_\theta(t)\) is the trajectory produced by the learned adapter for type \(t\), and \(G_\mu\) is the baseline consensus under the population \(\mu\), replace the paper’s finite sums over judges with expectations under \(\mu\), for example:
\[
\mathcal L_\mu(\theta)
=
\int_T\!\left[
\alpha\|R_\theta(t)-G_\mu\|_2^2
+\beta\bigl(1-\rho_p(R_\theta(t),G_\mu)\bigr)
\right]\,d\mu(t)
+\sigma\|\bar R_\theta-G_\mu\|_2^2,
\qquad
\bar R_\theta=\int_T R_\theta(t)\,d\mu(t).
\]
A concrete computational question is whether this calibration and its resulting ranking can be computed or approximated efficiently from a rational-mass support of size \(\tau\), with running time stated in the number of candidate models, benchmark comparisons, feature dimension, and input bit length. Repeated instances of one evaluator type can be processed by their mass. That is precisely the high-multiplicity version of the paper’s algorithmic task.
There is also a useful winner-robustness question tied to the paper’s claimed consensus stability. Freeze a deployed adapter, let \(S_\theta(t,c)\) be the resulting score contribution of evaluator type \(t\) to candidate \(c\), and let \(\gamma(t,t')\) be the cost of shifting evaluation capacity from one evaluator policy to another. What is the minimum cost of mass transfer that makes a target model \(c^\star\) win? Its constraints are
\[
\sum_t \mu'_t S_\theta(t,c^\star)
\ge
\sum_t \mu'_t S_\theta(t,c)
\quad\text{for every candidate }c,
\]
with \(\mu'\) obtained from the transfers. This is a continuous judge-population robustness problem in the same sense that bribery asks how much voter mass must move to change a winner. It asks whether UDA’s consensus ranking depends on a small, consequential share of the evaluator population—something the reported reduction in standard deviation does not answer.
The paper’s ten distinct judges do not rule out this regime. They describe one experimental instance; the relevant regime is a platform with many evaluator instances or evaluation capacity distributed across a smaller set of recurring policies. Nor does mass discard a relevant individual identity: the type contains the judge’s policy and the self-awareness features UDA uses. If prompt-specific behavior matters, it belongs in the type’s full benchmark profile; that may increase \(\tau\), but it does not make the question ill-posed.
These are new computational questions, not complexity results already proved by the paper, and the transfer-cost model would need to be specified for a particular application. That limits how directly they mirror the theorem. It does not support the stronger claim that no scenario yields a worthwhile mirror: UDA’s own population-level objective and ranking output make the evaluator-distribution version concrete.
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.
