| A unified access bound on comparison-based dynamic dictionaries (2008) | |||||||||||||||
Abstract | |||||||||||||||
| We present a dynamic comparison-based search structure that supports insertions, deletions, and searches within the unified bound. The unified bound specifies that it is quick to access an element that is near a recently accessed element. More precisely, if w(y) distinct elements have been accessed since the last access to element y, and d(x, y) denotes the rank distance between x and y among the current set of elements, then the amortized cost to access element x is O(miny log[w(y) + d(x, y) + 2]). This property generalizes the working-set and dynamic-finger properties of splay trees. Preprint submitted to Elsevier Science 31 January 2007 1 | |||||||||||||||
