Center node: "the cost of uncertainty in curing epidemics"
  Abstract: Motivated by the study of controlling (curing) epidemics, we consider the spread of an SI process on a known graph, where we have a limited budget to use to transition infected nodes back to the susceptible state (i.e., to cure nodes). Recent work has demonstrated that under perfect information (which nodes are/are not infected), the budget required for curing a graph precisely depends on its CutWidth. We develop a model for observation uncertainty, and show that even a minor degradation in the assumption of perfect knowledge of the state of the infection drastically alters the landscape -- infections that could previously be cured in sublinear time, now may require exponential time to cure. Our main result characterizes the necessary curing budget required as a function of the per-node observation uncertainty.
