组合Skyline的求解与更新算法
Algorithm for Solving and Updating Combinatorial Skyline
摘要
Abstract
Existing algorithms for querying combinatorial Skyline have low pruning efficiency and unsatisfactory computing speed for low-dimensional data set.Aiming at these problems,this paper proposes a fast algorithm for solving and updating combinatorial Skyline.It defines the related concept of dominant area and presents some pruning rules to prune lots of useless data.For points added or deleted,based on existing result,it takes corresponding operations according to the data partition,so as to update query results quickly.Experimental results show that the proposed algorithm can improve pruning efficiency and computation speed effectively.关键词
