WebJul 27, 2006 · We present an on-line strategy that enables a mobile robot with vision to explore an unknown simple polygon. We prove that the resulting tour is less than 26.5 times as long as the shortest watchman tour that could be computed off-line. Our analysis is doubly founded on a novel geometric structure called angle hull. WebWe prove that finding the minimum number of vision points, i.e., static guards, along a shortest watchman route is NP-hard. We provide a linear time algorithm to compute the …

WebThe optimum watchman route is nally obtained by folding back the shortest path. See Fig. 3 for anexample. Note that the watchman route computed by the unfolding method is optimum only with respect to the given fragment set. (It is thus possible to shorten the length of the current route by changing the watchman fragment set. WebWei-pang Chin, Simeon C.
