Optimized association rules are permitted to contain uninstantiated attributes. the optimization procedure is to determine the instantiations such that some measures of the roles are maximized. this paper tries to maximize interest to find more interesting rules. on the other hand, the approach permits the optimized association rule to contain uninstantiated numeric attributes in both the antecedence and the consequence. a naive algorithm of finding such optimized rules can be got by a straightforward extension of the algorithm for only one numeric attribute. unfortunately, that results in a poor performance. a heuristic algorithm that finds the approximate optimal rules is proposed to improve the performance. the experiments with the synthetic data sets show the advantages of interest over confidence on finding interesting rules with two attributes. the experiments with real data set show the approximate linear scalability and good accuracy of the algorithm
優化關聯規則允許在規則中包含未初始化的屬性.優化過程就是確定對這些屬性進行初始化,使得某些度量最大化.最大化
興趣度因子用來發現更加有趣的規則;另一方面,允許優化規則在前提和結果中各包含一個未初始化的數值屬性.對那些處理一個數值屬性的演算

Perfect pre - processing and post - processing function is one of the main factors to evaluate the vitality and market value of the finite element analysis system surveying today development of finite element analysis technology, most of which concentrate on establishing fine user interface, also has some limitation on application, and especially, the research on the visualization of arbitrary cut - plane is always in ascendants to realize the visual processing on cut - plane needs reprocessing the results of finite element analysis which have get, so the algorithm is two parts : seeking the physical value of cut - plane and drawing 2d contours, the former, based on the theory of stress on " arbitrary inclined plane " in physical mechanics, use the method of linear interpolation method to get the coordination and physical value of intersection between cut - plane and element arris ; the latter, based on the tables on elements, nodes, stress and strain, summarize a rapid algorithm of generating 2d contours based on the grid. this thesis synthesizes there two parts and get a visual processing program under fortran
