On-line Stream Merging with Max Span and Min Coverage

Abstract This 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 t...

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.

abstract	Abstract This 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. © Springer 2005

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.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Computational Mathematic</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Greedy Algorithm</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Competitive Ratio</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Performance Guarantee</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Simple Greedy Algorithm</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lam, Tak-Wah</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ting, Hing-Fung</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wong, Prudence W.H.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Theory of computing systems</subfield><subfield code="d">New York, NY : Springer, 1997</subfield><subfield code="g">38(2005), 4 vom: 28.
