自组织线性表在非等概率查找中具有较好的效率。本文在原有3种基本构造策略的基础上,提出一种新方法---移至中位策略。该策略优化自组织线性表中记录的调整方式,减少了累计记录比较次数,从而提高了查找响应速度。在实验测试中,提出平稳的查找过程和非平稳的查找过程的概念,并分别设计相应的测试用例。实验结果表明,移至中位策略的综合性能最好。
自組織線性錶在非等概率查找中具有較好的效率。本文在原有3種基本構造策略的基礎上,提齣一種新方法---移至中位策略。該策略優化自組織線性錶中記錄的調整方式,減少瞭纍計記錄比較次數,從而提高瞭查找響應速度。在實驗測試中,提齣平穩的查找過程和非平穩的查找過程的概唸,併分彆設計相應的測試用例。實驗結果錶明,移至中位策略的綜閤性能最好。

Self-organized linear lists are of a better efficiency in non-equal probability search .This paper puts forward a new method of moving to middle , based on three basic strategies .This method optimizes the adjustment method of recording in self-or-ganized linear lists , reduces the comparison times of cumulative record when conflicts occur so as to shorten the reaction of searching.In experimental tests , we proposed a concept on stationarity and non-stationarity of search process , and designed the corresponding test cases .The experiments show that the comprehensive properties of the new method are best .
