  • Non-orthogonal ray guarding 
    Sanders, I (1998)
    In an earlier paper the notion of a ray guard --'- a guard that can only see along a single ray, was introduced. The ray guarding problem is in siting the fewest possible such guards so that they guard all adjacencies ...
  • Partial edge visibility in linear time 
    Bilbrough, J; Sanders, I (1998)
    This research addresses the problem of partial edge visibility. This problem stems from work done in the ray guarding of configurations of adjacent rectangles [7]. In ray guarding these configurations it is necessary to ...
  • Ray guarding configurations of adjacent rectangles 
    Sanders, I; Lubinsky, D; Sears, M (2000)
    Guarding and covering problems have great importance in Computational Geometry. In this paper the notion of a ray guard, a guard that can only 'see' along a single ray, is introduced. The problem of siting the fewest ...
