A Study of Trie - like Structures under the Density Model
نویسنده
چکیده
We consider random tries constructed from sequences of i .i.d . random variables with a common density f on [0,1] (i.e., paths down the tree are carved out by the bits in the binary expansions of the random variables) . The depth of insertion of a node and the height of a node are studied with respect to their limit laws and their weak and strong convergence properties . In addition, laws of the iterated logarithm are obtained for the height of a random trie when jf 2 < ~. Finally, we study two popular improvements of the trie, the PATRICIA tree and the digital search tree, and show to what extent they improve over the trie.

Wavelet Linear Density Estimation for a GARCH Model under Various Dependence Structures
We consider n observations from the GARCH-type model: S = σ2Z, where σ2 and Z are independent random variables. We develop a new wavelet linear estimator of the unknown density of σ2 under four different dependence structures: the strong mixing case, the β- mixing case, the pairwise positive quadrant case and the ρ-mixing case. Its asymptotic mean integrated squared error properties are ...
متن کاملCompact Suffix Trees Resemble PATRICIA Tries: Limiting Distribution of the Depth
Suffix trees are the most frequently used data structures in algorithms on words. In this paper, we consider the depth of a compact suffix tree, also known as the PAT tree, under some simple probabilistic assumptions. For a biased memoryless source, we prove that the limiting distribution for the depth in a PAT tree is the same as the limiting distribution for the depth in a PATRICIA trie, even...
متن کاملDensity functional explorations of quadrupole coupling constants for BN, BP, AlN, and AlP graphene–like structures
Stabilizations and atomic level quadrupole coupling constant (CQ) properties have been investigated for graphene–like monolayers (G–monolayers) of boron nitride (BN), boron phosphide (BP), aluminum nitride (AlN), and aluminum phosphide (AlP) structures. To this aim, density functional theory (DFT) calculations have been performed to optimize the model structures and also to evaluate the CQ para...
متن کاملSmoothed Analysis of Trie Height
Tries are very simple general purpose data structures for information retrieval. A crucial parameter of a trie is its height. In the worst case the height is unbounded when the trie is built over a set of n strings. Analytical investigations have shown that the average height under many random sources is logarithmic in n. Experimental studies of trie height suggest that this holds for non-rando...
متن کاملSoil-Structure Interaction of Buried Pipes Under Cyclic Loading Conditions
The safety of lifelines, as the most important urban facilities, under different conditions highly depends on the safe design and performance of these buried structures. This cannot be achieved unless their actual behaviors are well understood and considered at the designing stage. A new physical model was developed in Amirkabir University of Technology to study the behavior of buried pipes und...
