We then do a performance investigation , comparing cache - oblivious algorithms with traditional ram - model algorithms . in the last , on the basis of thorough research , we present an optimal sub - linear working space cache - oblivious sorting algorithm . we conclude that cache - oblivious algorithms do outperform traditional ram - model algorithms when working on large data sets 接着通过性能测试,把高速缓存参数无关算法与传统的基于ram模型的算法做了比较,最后,在深入研究的基础上提出了一个最优的子线性工作空间的高速缓存参数无关的排序算法。
Using the f - ahp model algorithms that based on fuzzy number and interval arithmetic solve the multi - attributes and fuzzy problems of agricultural project appraisal . using entropy weight ranking of f - ahp is more efficiency . using a - cut and index of optimism x . estimate the uncertainty and preference of decision makers 用基于模糊数、区间数运算法则的f - ahp模型解决了农业项目投资评估的多属性及模糊性问题;采用熵权使得排序更加科学;通过置信度与乐观指数考虑了不确定性及决策者的风险态度。
As a result of modeling assumption study , i discuss a special kind of modeling assumption , relevance assumption , which defines the relation between model fragments and objects being modeled , and maps concrete model goal to model fragments . i consider cm in the view of relevance reasoning and develop a qualitative modeling algorithm , in which each model fragment is being related to some kinds of modeling goal and task 在此基础上,本文继续研究了一类特殊的模型假设,即关联假设,后者从模型片断与被描述对象间的关系出发,将模型片断与建模任务联系起来,本文提出基于关联假设的推理算法,就是利用关联假设来辅助定性建模任务中的模型片断选取。
In this paper , i have established a appraisement index system after synthetically consideration affecting factor of trolleybus and bus in managing quality , determined right number of each index by grade analysis law , determined appraisement grade of each index by investigating to queue up , determined appraisement matrix by expert inquiry , calculated subordinating level which beijing ' s managing quality of trolleybus and bus in managing quality to each appraisement grade by " m ( , ) " model algorithm in vague mathematics . according to identification principle , i have reached conclusion 本论文在综合考虑公共电汽车运营质量影响因素的前提下,确定了公共电汽车运营质量评价指标体系,采用层次分析法确定指标权数,通过调查排队来确定各指标的评价等级,通过专家调查法确定评价矩阵,利用模糊数学中m ( ? ? )模型算法计算一个城市公共电汽车运营质量对“优、良、中、差”的隶属度,根据识别原则,得出结论。
