Research on an Efficient Method for GNN Query Algorithm
Huang Ka · Quality and Technical Supervision Research · 2014
Given a collection of P and Q, then GNN is returned by the query object p in P, p meets to set function all objects in the Q f the minimum distance. There are several methods for GNN. This paper raises the vp-GNN algorithm, which is characterized in that does not use any index case, also can effectively cut to spatial data in the database, reduce the search area and improve the efficiency of GNN query.
