Abstract
We consider the Robber Locating Game, where an invisible moving robber tries to evade the pursuit of one or more helicopter cops, who send distance probes from anywhere on the graph. In this paper, we attempt to propose two useful constructions for general problems in this game: a state variable that describes the available game information for the cops, and a Cop Strategy Graph construction that presents all possibilities of the game given a deterministic cop strategy. Then we will use them, along with algorithms and pseudo-code, to explain the relationship between two graph parameters, the localization number and the subdivision number. Researchers have shown that the later has a linear relationship with the former, while the other direction does not. We will revisit their proofs, consolidate the essential correspondence between the two numbers via our proposed constructions, and show…
