Abstract
We consider three graph-theoretical models of spread and competition motivated by biological applications and also by spread of opinions in social networks and fires in geographical areas. We modify the voter model of Clifford, Sudbury, Holley, and Liggett by introducing confidence levels. In the voter model, a group of voters has opinions “yes” or “no, ” interpreted as infected or non-infected in a disease application. As time progresses each voter’s opinion is influenced by his or her neighbors, with the confidence level of a voter determining how quickly the voter reconsiders his or her opinion (how quickly a person might change disease state). We show that the voter model with confidence levels always results in a uniform opinion, and we determine the probability of each uniform opinion based on the initial opinions and–what is unusual in this subject–on the structure of the underlying graph. We also consider a perfectly contagious disease, where vertices adjacent to infected vertices become infected at every discrete time step. The only intervention allowed is a limited number of vaccinations per time step. This model of disease spread is equivalent to a model of fire spread introduced by Hartnell where firefighters correspond to vaccinations.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
