An algorithm is presented that stations guards in such a room so that every interior point is visible to some guard. The algorithm partitions the polygon into L-shaped pieces, a subclass of star-shaped pieces, and locates one guard within each kernel. The algorithm runs in O(n log n) time in the worst case for a polygon of n vertices.","lang":"eng"}],"publication_status":"published","doi":"10.1016/S0734-189X(84)80041-9","_id":"4118","article_type":"original","date_created":"2018-12-11T12:07:02Z","publist_id":"2002","citation":{"short":"H.
