Efficient full-text keyword search remains a challenging problem in P2P systems. Most of the traditional keyword search systems on DHT overlay networks perform the join operation ...
Efficient full-text searching is a big challenge in Peer-to-Peer (P2P) system. Recently, Distributed Hash Table (DHT) becomes one of the reliable communication schemes for P2P. Som...
Local search procedures for solving satisfiability problems have attracted considerable attention since the development of GSAT in 1992. However, recent work indicates that for m...
Algorithms based on following local gradient information are surprisingly effective for certain classes of constraint satisfaction problems. Unfortunately, previous local search a...
Hundreds of millions of users each day submit queries to the Web search engine. The user queries are typically very short which makes query understanding a challenging problem. In...
