Webproblem, i.e. fixed m-watchman routes problem, each route passes through a given point. In this paper, we propose the first linear-time algorithm to compute the optimum fixed 2-watchman routes under the MinMax criterion. Index Terms—Computational geometry, Multiple fixed watchman routes, Visibility polygon, Staircases. WebOct 1, 1990 · In this paper we present an O (n4, log logn) algorithm to find a shortest watchman route in a simple polygon through a point,s, in its boundary. A watchman route is a route such that each point in the interior of the polygon is visible from at least one point along the route.
