Dynamic 3-sided planar range queries with expected - delab-auth
... hB-trees and various R-trees have been proposed. A recent survey can be found in [16]. Often these data structures are used in applications, because they are relatively simple, require linear space and perform well in practice most of the time. However, they all have highly sub-optimal worst case pe ...

A Fully Retroactive Priority Queues
... Naturally, we cannot hope to directly update this picture each time our priority queue changes and hope to retain efficient performance. A long cascade of this sort will incur a linear-cost update: much too expensive. Fortunately, in the partially retroactive case, we only need to be concerned with ...
