Translating polygons with applications to hidden surface removal,ects that are closer to the viewpoint are displayed later than objects that are farther away. Thus our technique can be used to generate displaying orderings for polyhedral terrains. One of the main advantages of our approach is that it can easily be adapted to handle perspective views within the same time and space bounds.

Fast updating of well-balanced trees,rtized bound on the dictionary problem..Trees of optimal and near-optimal height may be represented as a pointer-free structure in an array of size .(.). In this way we obtain an array implementation of a dictionary with .(log .) search cost and .(log..) update cost, allowing interpolation search to improve the expected search time.

How to update a balanced binary tree with a constant number of rotations,he result provides insight into the constant linkage cost updating algorithms for red-black, red-.-black, and half-balanced trees. Moreover, it enables us to design new constant linkage cost updating algorithms for these as well as for other classes of trees. Specifically, we give constant linkage cost updating algorithms for α-balanced trees.

Lower bounds for monotonic list labeling,estriction on the algorithms, that Ω(. log..) relabelings are necessary when inserting . items into list monotonically labeled from a label space of size .. We also prove that Ω(. log .) relabelings are required in the case of a label space of polynomial size.

Sorting shuffled monotone sequences, .(. log .) time, without knowing . beforehand, which is optimal in a comparison-based model. In the worst case Slabsort degenerates to a hybrid of Melsort and Exact Quicksort and runs in Θ(. log .) time. Further, . is shown to capture various kinds of existing order proposed in the literature.

Approximating maximum independent sets by excluding subgraphs,obtain the same performance guarantee for graph coloring. The results can be combined into a surprisingly strong . performance guarantee for the clique and coloring problems..The framework of . algorithms is presented. We survey the known approximation algorithms for the independent set (clique), co
