Traveling along the k-transmitter watchman route, either all points in P or a discrete set of points S⊂ P must be k-visible to the watchman. ...
WebFinding optimum watchman routes in simple polygons is closely related to the problem of finding shortest routes that visit a set of convex polygons in the plane in the presence of … WebNov 1, 2024 · By drawing a connection to the watchman’s route problem, we find a set of conditions that must be satisfied by the p-route. Then we propose a metric for tracking to estimate a sufficient speed for the observer given the geometry of the environment.
