Abstract

fetched live from OpenAlex

We consider the game of Cops and Robber played with infinitely many cops on countable graphs. We give a sufficient condition - the strongly 1-e.c.\ property - for the cop number to be infinite. The cop density of a finite graph, defined as the ratio of the cop number and the number of vertices, is investigated. In the infinite case, the limits of the cop densities of chains of finite graphs are studied. For a strongly 1-e.c.\ graph, any real number in [0,1] may be realized as a cop density of the graph. We prove that if the cop number is infinite, then there is a chain with cop density 1; however, we give an example with cop number 1 and cop density 1. We consider the cop density of finite connected graphs, and prove that for the G(n,p) random graph, almost surely the cop density is concentrated around lnn.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
