** A multi-objective algorithm based upon particle swarm optimisation, an efficient data structure and turbulence**

free download

Algorithm (MOA) based upon the Particle Swarm Optimisation (PSO) heuristic. It utilises an order put upon members of non-dominated sets by the recent dominated tree data structure to facilitate the choosing of abestglobal individual for each member of the swarm, in order to

** Prefix hash tree: An indexing data structure over distributed hash tables**

free download

ABSTRACT Distributed Hash Tables are scalable, robust, and self-organizing peer-to-peer systems that support exact match lookups. This paper describes the design and implementation of a Prefix Hash Treea distributed data structure that enables more

** The grid file: a data structure designed to support proximity queries on spatial objects**

free download

Ahgtract We describe a technique for storing large sets of spatial objects so that proximity queries are handled effciently as part of the accessing mechanism. This technique is based on a transformation of spatial objects into points in higher-dimensional spaces and on a data

** SigGraph: Brute Force Scanning of Kernel Data Structure Instances Using Graph-based Signatures.**

free download

Brute force scanning of kernel memory images for finding kernel data structure instances is an important function in many computer security and forensics applications. Brute force scanning requires effective, robust signatures of kernel data structures. Existing approaches

** Iterative language model estimation: efficient data structure algorithms**

free download

Despite the availability of better performing techniques, most language models are trained using popular toolkits that do not support perplexity optimization. In this work, we present an efficient data structure and optimized algorithms specifically designed for iterative parameter

** HAT-trie: a cache-conscious trie-based data structure for strings**

free download

Tries are the fastest tree-based data structures for managing strings in-memory, but are space-intensive. The burst-trie is almost as fast but reduces space by collapsing trie-chains into buckets. This is not however, a cache-conscious approach and can lead to poor

** The rainbow skip graph: a fault-tolerant constant-degree distributed data structure **

free download

We present a distributed data structure , which we call the rainbow skip graph. To our knowledge, this is the first peerto-peer data structure that simultaneously achieves high fault- tolerance, constant-sized nodes, and fast update and query times for ordered data . It is a

** CT-PRO: A Bottom-Up Non Recursive Frequent Itemset Mining Algorithm Using Compressed FP-Tree Data Structure .**

free download

Frequent itemset mining (FIM) is an essential part of association rules mining. Its application for other data mining tasks has also been recognized. It has been an active research area and a large number of algorithms have been developed. In this paper, we propose another

** A data structure and query algorithm for a database of areal entities**

free download

Data structures for geographic information systems desirably should support the efficient execution of a number of query types based on spatial relationships. This paper pursues this goal by proposing a data structure for entities of typearea. The approach is based on

** Density or distinction The roles of data structure and group detection methods in describing adolescent peer groups**

free download

Despite cross-disciplinary interest in social influence among adolescent peer groups, significant variations in collecting and analyzing peer network data have not been explored, so it is difficult to disentangle substantive and methodological differences in peer influence

** PDS A three-dimensional data structure for proof plans**

free download

We present a new data structure that enables to store three-dimensional proof objects in a proof development environment. The aim is to handle calculus level proofs as well as abstract proof plans together with information of their correspondences in a single structure Sets are a basic data structure in artificial intelligence. Embedding this datastructure into deductive processes based on resolution requires inventing a suitable unification algorithm (ACI-unification algorithm) respecting the particular properties of the constructor function The visibility diagram VIS (S) of a set S of line segments in the plane which dont intersect except possibly at their boundary points is a subdivision (cell complex) of a certain two- dimensional space whose points correspond to lines in the plane. This geometric object may
