AbstractThis paper introduces the notions of span and coverage for analyzing the performance of on-line algorithms for stream merging. It is shown that these two notions can solely determine the competitive ratio of any such algorithm. Furthermore, we devise a simple greedy algorithm that attains the ideal span and coverage, thus giving a better performance guarantee than existing algorithms. The new notions also allow us to obtain a tighter analysis of existing algorithms. © 2005 Springer Science+Business Media, Inc.
