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 。 -
