Abstract

fetched live from OpenAlex

We study various properties of least cost paths under independent and identically distributed (iid) disorder for the complete graph and dense Erdős–Rényi random graphs in the connected phase, with iid exponential and uniform weights on edges. Using a simple heuristic, we compute explicitly limiting distributions for (properly recentered) lengths of shortest paths between typical nodes as well as multiple source destination pairs; we also derive asymptotics for the number of edges on the shortest path, namely, the hopcount, and find that the addition of edge weights converts these graphs from ultrasmall world networks to small world networks. Finally we study the Vickrey–Clarke–Groves measure of overpayment for the complete graph with exponential edge weights and show that the complete graph is far from monopolistic for large n.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
