  1. In this paper, we study an on - line version of the two - dimensional bin packing problem that is the problem of packing a list of rectangular items into a minimum number of unit - square bins in an on - line manner. an on - line algorithm called rtdh ( refined two dimensional harmonic ) is proposed and analyzed. we show that rtdh can achieve an asymptotic worst - case ratio of less than 2. 7687, which beats the best - known bound 2. 85958

    目前,對該問題的研究有各種演算法,主要有harmonic和round演算法,本文針對harmonic和round演算法存在的問題,提出一種演算法rtdh ( refinedtwodimensionalharmonic ) ,做了相應的分析,並且給出了該演算法的最壞性能比是2 . 7687的證明,這個結果刷新了目前最好的結果2 . 85958 。
