متن کاملNew Deterministic Algorithms for Counting Pairs of Intersecting Segments and Off-Line Triangle Range Searching
We describe a new method for decomposing planar sets of segments and points. Using this method we obtain new efficient deterministic algorithms for counting pairs of intersecting segments, and for answering off-line triangle rang'e queries. In particular we obtain the following results: (1) Given n segments in the plane, the number K of pairs of intersecting segments is computed in time O(nl+ f...
