Fundamental parametrization-to-depth trade-off
Determine whether the conjectured trade-off governed by \(q=N_{\mathrm{params}}/\bar T\)—where low values favor algorithmic generalization but impair trainability—is fundamental, or whether some substrates can simultaneously provide strong algorithmic inductive bias and efficient searchability.

Our evidence for both halves is partial, and whether the trade-off is fundamental, or some substrates can be both well-biased for algorithmic solutions and efficiently searchable, remains open.

Because we vary only the training-set size, this consistency does not by itself test the bound's dependence on circuit complexity and parameter reuse, which we leave as an open experimental question.
