Visibility problems deal with placing a minimum number of tr ansmitting stations in a region thus covering a maximum number of co mmunication needs. Here we investigate some variants of such proble ms e.g. i) given a polygonP with weights on the vertices find at most k convex subpolygonsCi of P (possibly overlapping) withV(Ci) ⊆ V(P) so that the weight of the vertices is a maximum, and ii) given a polygon (possibl y with holes) andk available vertex (or edge) guards maximize a) the length of… CONTINUE READING
