We describe an algorithm for finding a canonical image of a set of points under the action of a permutation group. Specifically if we order images by sorting them and ordering t...
Inverted index data structures are the key to fast search engines. The predominant operation on inverted indices asks for intersecting two sorted lists of document IDs which might...
Clustering is an important characteristic of most sensor applications. In this paper we define COSMOS, the Cluster-based, heterOgeneouS MOdel for Sensor networks. The model assum...
In recent years, the development of multi-objective evolutionary algorithms (MOEAs) hybridized with mathematical programming techniques has significantly increased. However, most...
Flash memory affects not only storage options but also query processing. In this paper, we analyze the use of flash memory for database query processing, including algorithms that...
